Atrial fibrillation (AFib) is a heart condition affecting approximately 2.7 million Americans yearly. It causes irregular heartbeats, leading to serious health problems such as stroke and other complications. The good news is that there are many ways to prevent AFib from developing in the first place. You can read below some of the AF epidemiology facts as made available in this research (Ref. Link).

Research shows that making certain lifestyle changes, such as losing weight, increasing physical activity, and managing risk factors, reduces the impact of AFib. Studies have found that weight loss and improved fitness significantly reduce AFib. This evidence suggests that managing AF should focus on lifestyle and risk factor modification. Public health initiatives and policy recommendations in these areas may effectively reduce the incidence and impact of AFib.

Does atrial fibrillation increase the risk of stroke and other heart issues?

Yes, atrial fibrillation (AFib) increases the risk of stroke and other heart issues. AFib is an irregular heartbeat that can cause blood to pool in the heart, which can lead to blood clots. These clots can then travel to the brain and cause a stroke. Additionally, AFib can damage the heart muscle over time, increasing the risk of other heart issues such as heart failure and heart attacks. People with AFib also tend to have other underlying health conditions that increase the risk of stroke and heart issues.

Is AFib more common in older people?

If you’re older and have a heart condition, you’ve likely been diagnosed with AFib. The condition is more common in people over age 65 than in any other age group. Also, AFib occurs more frequently in men than women; however, its prevalence increases significantly with age for both sexes. This is likely because the risk factors for AFib increase with your age. You are prone to develop hypertension, obesity, and diabetes. Additionally, as the heart and blood vessels age, they may become more prone to developing structural and electrical abnormalities that can lead to AFib. As the heart muscle weakens with age, it can no longer pump blood effectively, which can lead to the development of AFib.

What are the medications that increase the risk of AFib?

Certain medications may increase your risk of AFib. These include:

Beta-blockers, which are used to treat high blood pressure and heart disease. These medications are commonly used to treat hypertension and heart failure. However, they slow the heart rate, which can make AFib worse.
Calcium channel blockers, which are used to treat high blood pressure and angina (chest pain). These medications are also used to treat hypertension and are known to slow the heart rate, which can exacerbate AFib.
Non-steroidal anti-inflammatory drugs (NSAIDs): These medications, such as ibuprofen and naproxen, increase the risk of AFib by increasing blood pressure, which adds stress to the heart.

Talk to your doctor if you experience any signs of AFib.

If you experience any of the following symptoms, it’s essential to talk to your doctor right away:

Palpitations (a feeling of your heart racing or pounding)
Fainting (syncope)
Dizziness and lightheadedness
Shortness of breath and chest pain

AFib is a serious but preventable condition.

AFib is a serious but preventable condition. It can be treated, and in many cases, one can control the symptoms with medication or surgery. But the best way to prevent AFib is by knowing your risk factors and maintaining healthy habits that reduce your chances of developing it in the first place. Talk to your doctor if you experience any signs of AFib and learn how to lower your risk of stroke or other heart-related events with lifestyle changes like quitting smoking, losing weight, and exercising regularly.

How do you monitor your heart health for AFib?

Heart rate monitoring is vital for detecting and managing atrial fibrillation (AFib). Several different types of heart rate monitoring methods can be used to detect AFib, including:

Holter monitoring: This method involves wearing a small, portable device that continuously records the heart’s electrical activity for a day or two. As you carry out your daily activities, this device can detect AFib episodes that may not be apparent during a doctor’s visit.
Continuous monitoring with a wearable device: Wearable devices like chest strap smart heart monitors can continuously monitor the heart rate and detect irregular patterns that may indicate AFib.

By monitoring the heart rate, doctors can detect AFib episodes, understand the patient’s specific symptoms, and make more informed treatment decisions. Also, patients can use these devices to monitor their heart rate and notify their doctor if they notice any irregular patterns. It’s worth noting that a heart rate monitor should be used in conjunction with other diagnostic tools, such as an electrocardiogram (ECG), to confirm a diagnosis of AFib. You need a Smart Heart Monitor such as the Frontier X2 to ensure that you are tracking your heart health consistently.

Are you overwhelmed by the numerous weight loss methods and diet plans advertised for heart health? In this blog, we examine the DASH diet and evaluate the scientific evidence behind this diet and helpful resources for you. The DASH diet, which stands for Dietary Approaches to Stop Hypertension, is an eating plan designed to lower blood pressure and improve overall health. The diet emphasizes fruits, vegetables, whole grains, lean protein, and low-fat dairy products and limits saturated fat, cholesterol, and total fat. The DASH diet also includes moderate amounts of nuts, seeds, and legumes.

Research has shown that the DASH diet can lower blood pressure and reduce the risk of heart disease, stroke, and other health problems. The DASH diet may also help prevent or improve other health conditions such as osteoporosis, cancer, and kidney stones. The DASH diet is a healthy eating plan that can be followed by anyone looking to improve their overall health and well-being. We have listed five things you should know about the DASH diet for heart health.

What Does The Original DASH Diet Plan Include?

The original DASH diet plan, which stands for Dietary Approaches to Stop Hypertension, includes a focus on eating nutrient-dense foods, such as:

Fruits and vegetables: These foods are high in potassium, magnesium, and calcium, which can help lower blood pressure.
Whole grains: Whole grains, such as whole wheat bread, oatmeal, and brown rice, are rich in fiber, vitamins, and minerals.
Lean protein: The DASH diet includes lean protein sources, such as chicken, fish, and legumes, low in saturated fat and cholesterol.
Low-fat dairy products: The diet promotes low-fat dairy products, such as milk, yogurt, and cheese, which are rich in calcium and other nutrients.
Nuts, seeds, and legumes: These foods are included in moderate amounts in the DASH diet, as they are a good source of protein, healthy fats, and fiber.

The table below includes examples of daily and weekly servings that meet DASH eating plan targets for a 2,000-calorie-a-day diet. (Ref. Link)

Food Group	Daily Servings
Grains	6–8
Meats, poultry, and fish	6 or less
Vegetables	4–5
Fruit	4–5
Low-fat or fat-free dairy products	2–3
Fats and oils	2–3
Sodium	2,300 mg* (while 1,500 milligrams (mg) sodium lowers blood pressure even further than 2,300 mg sodium daily.)
	Weekly Servings
Nuts, seeds, dry beans, and peas	4–5
Sweets	5 or less

What Are The DASH Diet Sodium Limits?

The original DASH diet plan includes limits on dietary sodium intake, intending to reduce blood pressure and improve overall health. The DASH diet plan consists of three levels of sodium intake:

The “regular” DASH diet: This diet level includes a daily sodium intake of 2,300 milligrams (mg). This is the equivalent of about one teaspoon of salt.
The “intermediate” DASH diet: This diet level includes a daily sodium intake of 1,500 mg. This is the equivalent of about 2/3 teaspoon of salt.
The “low” DASH diet: This diet level includes a daily sodium intake of 1,200 mg. This is the equivalent of about 1/2 teaspoon of salt.

Most of us consume more sodium than we need. The American Heart Association (Ref. Link) recommends no more than 2,300 mg per day and ideally less than 1,500 mg per day for most adults. The DASH diet is consistent with these recommendations. It encourages one to limit the intake of processed foods and restaurant meals, which are often high in sodium.

Can You Turn Your Favorite Recipes DASH Diet Friendly?

Yes, you can turn recipes dash-friendly. Make your favorite recipes DASH-compliant by:

Decreasing the amount of salt by not using the salt shaker and limiting high-sodium sauces.
Incorporating more vegetables and fruits into the recipe.
Using less meat or selecting lean, skinless meats.
Substituting butter or solid oils with unsaturated oils such as olive, canola, or avocado.
Using whole grains instead of processed white bread and grains.

We recommend you make gradual changes over days or weeks to make it easier to adjust and make DASH a part of your daily routine:

Gradually increase your daily intake of vegetables by adding a serving at lunch one day and dinner the next, and incorporate fruit into one meal or snack.
Gradually increase your use of fat-free and low-fat dairy products to three servings per day.
Gradually limit your intake of lean meats to 6 ounces per day, about 3 ounces per meal, roughly the size of a deck of cards.
If you usually eat large portions of meat, gradually reduce the amount for days or weeks by cutting it back by half or a third at each meal.
Incorporate two or more meatless meals per week in your diet.

What Are The Other Lifestyle Changes To Consider with DASH Diet?

Following the DASH diet and making these lifestyle changes together can lead to better health and well-being.

Regular physical activity: Regular physical activity is essential for maintaining a healthy weight and reducing the risk of heart disease and other health problems. Aim for at least 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous-intensity aerobic activity per week. Add a Smart Heart Monitor such as the Frontier X2 and easily track your heart health.
Maintaining a healthy weight: Being overweight or obese increases the risk of heart disease and other health problems. Ensure that you achieve your target weight as per your height. This can help lower blood pressure and improve overall health.

As yogis, you are always looking for ways to improve your practice. As it turns out, you can also use yoga to improve heart rate variability (HRV). HRV is defined as the variation in time between heartbeats and is measured by electrocardiography (ECG).

Is Yoga a Powerful Tool for Heart Rate Variability?

Yoga practices such as deep breathing, meditation, and specific postures have been found to increase HRV. Deep breathing practices in yoga, such as pranayama, can help regulate the breath and the nervous system, which can help improve HRV. Meditation and mindfulness practices can also help reduce stress and anxiety, negatively impacting HRV.

Certain postures in yoga also help to improve cardiovascular function and increase blood flow, which can improve HRV. Yoga postures that require balance and stability, such as tree pose and warrior pose, can also help to improve HRV by challenging the body to adapt to changes in position.

Yoga also positively impacts cardiovascular health by reducing blood pressure, cholesterol, and glucose levels and improving heart function. It’s worth noting that the effects of yoga on HRV may vary depending on the individual and the specific yoga practices s/he follows.

How does yoga help improve heart rate variability?

Yoga Can Help Improve Sleep

If you’re having trouble falling asleep, yoga can help. Yoga has been shown to reduce insomnia and snoring, two common sleep issues. A 2015 study published in The Journal of Alternative and Complementary Medicine found that practicing restorative yoga helped participants fall asleep faster, sleep more deeply and wake up less often throughout the night. Another benefit of practicing restorative poses before bedtime is improving heart rate variability (HRV), which is associated with better sleep quality and overall health.

Yoga Can Help with Stress Management

Yoga is the perfect solution if you’re looking for a way to manage stress. Stress is one of the most significant risk factors for heart disease and can impact your health in many ways. Stress can cause you to feel tense or anxious, which is not suitable for your body. It also increases cortisol levels, which leads to weight gain around the midsection (aka belly fat). Even if you don’t realize it, stress puts extra pressure on your body’s organs, like the heart and lungs. If this goes on long enough without any time spent relaxing or sleeping well, it can lead to severe problems such as high blood pressure or even heart failure.

Yoga has been shown again and again in studies how effective it is at reducing stress levels by increasing heart rate variability (HRV). Heart Rate Variability measures the variation between consecutive beats. When HRV rises, there are more fluctuations between beats, so each beat isn’t exactly alike, which helps regulate breathing patterns during exercise.

Yoga Can Support Mental Well-Being

Yoga is a powerful tool for improving mental well-being. The practice can help people who suffer from depression or anxiety and those experiencing stress and PTSD. Yoga has also proven to enhance the quality of life for those with mental health issues by reducing symptoms such as insomnia and fatigue. It also helps people feel more empowered over their own lives while increasing their ability to cope with stressful situations.

Yoga can improve cardiovascular health.

Yoga may be what you need if you’re looking for a way to improve your cardiovascular health. Yoga can help improve sleep quality, reduce stress and anxiety, and boost mental well-being. These effects are linked to lower blood pressure–a significant risk factor for heart disease.

How to Incorporate Yoga into Your Life

Getting started with yoga is the first step to improving your heart rate variability. If you need help determining where to begin, try starting with a few minutes of yoga daily. You can do this at home or the gym (or both). As you get better at regularly practicing, ensuring that your body has enough rest and recovery time between sessions, it will become easier for your body/mind to connect during these practices. Add a Smart Heart Monitor such as the Frontier X2 to your fitness routine and ensure that you track your heart health consistently.

Frequently Asked Questions:

What is heart rate variability (HRV)?

HRV is a measure of the variation in time between consecutive heartbeats. It indicates your body’s ability to adapt to stressful situations. Usually, a healthy HRV indicates a well-functioning nervous system.

How does yoga impact HRV?

Yoga practices such as deep breathing, meditation, and specific postures have been found to increase HRV. Yoga can help to regulate the breath and the nervous system, reduce stress and anxiety, and improve cardiovascular function. This leads to an increase in HRV.

Which yoga practices are best for improving HRV?

Deep breathing practices such as pranayama and meditation are effective in improving HRV. Yoga postures such as tree pose and warrior pose help to improve HRV by challenging the body to adapt to changes in position.

Is there any risk in practicing yoga for HRV?

Yoga is generally considered safe for most people. However, it’s always a good idea to consult a healthcare professional before starting any new exercise program, especially if you have any pre-existing medical conditions, such as hypertension.

Can I improve my HRV by practicing yoga alone?

Yoga can be an effective tool for improving HRV. However, you should use it with a healthy diet, regular physical activity, and stress management techniques. A holistic approach to overall health and well-being is recommended for the best results.

Quitting smoking is a tremendous step towards improving your health. By giving up smoking, you allow your lungs to heal and experience improved breathing. Additionally, the benefits of quitting smoking for your heart health are numerous and begin almost immediately. Make 2023 the beginning of a new chapter for yourself and join many individuals who have successfully quit smoking.

Smoking is a significant risk factor for heart disease and has been linked to various cardiovascular conditions. Nicotine, the addictive chemical found in tobacco, causes a rise in blood pressure and heart rate, which can damage the heart and blood vessels over time. Smoking prevalence estimates from the Australian Health Survey 2014–2015 show the damage that tobacco smoking causes across the entire cardiovascular system. (Ref. Link)

What are the heart health risks associated with smoking?

Smoking can lead to the development of atherosclerosis, a condition in which plaque builds up inside the arteries, making them narrower and less flexible. This can restrict blood flow to the heart, increasing the risk of a heart attack. The chemicals in tobacco smoke can also damage the walls of the arteries, causing inflammation and plaque formation. Coronary artery disease, a specific type of atherosclerosis, affects the blood vessels that supply the heart with oxygen and nutrients. Smoking increases the risk of plaque buildup in these vessels, which can lead to a heart attack or other serious complications. Smoking also increases the risk of blood clots, which can lead to a heart attack or stroke. Nicotine in the smoke causes the blood to become sticky and more likely to clot, which can block the flow of oxygen to the heart or brain. Smoking also increases the risk of peripheral artery disease, which occurs when plaque buildup in the arteries reduces blood flow to the legs and feet. It also increases the risk of an abdominal aortic aneurysm – a bulging or weakening of the aorta wall, the major blood vessel that supplies blood to the body.

What is the link between smoking frequency and risk of heart disease?

The risk of heart disease from smoking is directly related to the number of cigarettes smoked daily and the duration of smoking. The longer a person smokes and the more cigarettes they smoke per day, the greater their risk of developing heart disease. Secondhand smoke, also known as passive smoke, harms heart health too. Non-smokers exposed to passive smoke have a 30% higher risk of developing heart disease than non-smokers who are not exposed to secondhand smoke. Quitting smoking can significantly improve heart health. The risk of heart disease begins to decrease soon after quitting and continues to decline as time passes. The risk of heart attack also decreases; within a year of quitting, the risk of a heart attack is about half that of a continuing smoker.

How to quit smoking?

Quitting smoking can be challenging, but it’s one of the best things you can do for your health. Here are some tips to help you quit smoking:

Set a quit date: Choose a specific date to quit smoking, and plan how you will handle cravings and triggers on that day and in the days and weeks that follow.
Identify your triggers: Think about the situations, emotions, or activities that make you want to smoke. Once you know your triggers, you can develop strategies to avoid or manage them.
Get support: Tell your friends and family about quitting, and ask for their support. You can also seek help from a quitline, your healthcare provider, or a support group.
Nicotine replacement therapy: Nicotine replacement therapy (NRT) can help reduce cravings and withdrawal symptoms associated with quitting smoking. NRT comes in different forms, such as gum, patches, lozenges, inhalers, and nasal sprays.
Medications: Several prescription medications can help with quitting smoking, such as bupropion and varenicline. These medications can reduce cravings and withdrawal symptoms and increase the chances of success.
Relaxation techniques: Practice techniques such as deep breathing, meditation, and yoga to help reduce stress and manage cravings.
Avoid alcohol: Avoiding alcohol can help reduce cravings and make it easier to resist smoking.
Reward yourself: Celebrate your milestones, such as reaching one week, one month, or three months smoke-free. Treat yourself to something you’ve been wanting, or put the money you would have spent on cigarettes into a savings account.

It’s important to remember that quitting smoking is a process and it may take several attempts before you are successful. If you slip up and smoke, don’t give up. Instead, think about what led to the slip-up and analyze how you can avoid that situation in the future. Also, it’s worth mentioning that the success rate of quitting smoking is higher when a combination of strategies is used, such as NRT and medications, combined with behavioral support.

Quitting smoking can be difficult, but it’s worth it. Setting a quit date, identifying triggers, seeking support, using Nicotine Replacement Therapies and medications, practicing relaxation techniques, avoiding alcohol, and rewarding yourself can help increase the chances of success. Remember that quitting smoking is a process. If you slip up, don’t give up. Seek professional help, and keep trying. Beyond quitting cigarettes, the best way to make sure your heart is healthy is to use a smart heart monitor that constantly keeps track of your cardiac health.

Studies have shown that a significant proportion of COVID-19 patients experience cardiac involvement, which can manifest as palpitations, arrhythmias, or changes in heart rate. This is believed to be due to inflammation caused by the virus and the body’s immune response to it.

What are the effects of coronavirus on the heart and circulatory system?

COVID-19 has many adverse effects on the heart like increased heart rate and heart palpitations, blood clots, damage to the heart from a lack of oxygen and nutrients, inflammation of the heart muscle called broken heart syndrome. People with existing heart and circulatory conditions are at a greater risk for heart complications from Covid-19, although these complications are also observed in those without pre-existing heart disease. This is because the virus is thought to damage the endothelial lining (inner lining) of blood vessels. This can lead to blood clotting, leaky blood vessels, reduced blood supply to other parts of the body.

Heart Palpitations After COVID

Many people who have recovered from a COVID-19 infection may continue to experience side effects for months, and in some cases, these symptoms can persist for up to six months or longer post-infection. Heart palpitations refer to sensations of a fast or irregular heartbeat, including pounding, fluttering, or skipping beats. While usually not harmful, it is important to seek medical advice if palpitations persist or worsen, or if you have pre-existing heart disease. Medical attention may be required in certain situations such as chest pain, dizziness, prolonged or intense palpitations, or other heart complications.

Long COVID is believed to cause heart palpitations due to inflammation caused by the virus and the body’s immune response to it. The virus can cause inflammation in the heart muscle (myocarditis) and blood vessels (vasculitis), which can lead to changes in heart rate and rhythm. Additionally, Long COVID patients have been reported to have high levels of cytokines, which are inflammatory molecules that can affect the heart and cause palpitations. The exact mechanisms by which the virus causes these changes are still being studied, but it is known that the virus can directly infect the heart and cause myocarditis, which can be responsible for heart palpitations.

Understanding Long COVID Palpitations: Symptoms to Watch For

The symptoms of palpitations associated with Long COVID include:

A sensation of your heart beating fast, hard, or irregularly
Fluttering or “skipping” beats
A sensation of “thumping” or “pounding” in your chest
Dizziness or lightheadedness
Shortness of breath
Chest pain or discomfort
Fatigue

It’s important to note that these symptoms can be caused by other conditions as well, so it’s important to consult with your cardiologist if you experience any of these symptoms. They will be able to diagnose the cause of your heart palpitations and recommend appropriate treatment options after the necessary tests.

Long COVID and Heart Rate: Can post-COVID affect your heart’s rhythm?

Many people have noticed an increase in heart rate after recovering from COVID. Normal heart rate ranges from 60 to 100 beats per minute; an increase in this rate, resulting in tachycardia, is of concern in “long haulers”. Majority of long haulers experience a rapid heart rate (Ref. Link) due to prolonged illness or inactivity. Some may experience an increase in the heart rate while standing which is called postural orthostatic tachycardia syndrome (POTS). This is caused by the abnormality in the Autonomic nervous system (ANS) which controls the blood flow back to the heart. Researchers attribute the increase in heart rate following infection with Covid to the virus and immune response affecting the autonomic nervous system (rather than heart itself) and lack of physical activity. The majority of these patients’ cardiac test results are normal. Other common causes of an elevated heart rate include dehydration, stress or anxiety, exercise, caffeine, or the introduction of a new medication. Temporary variations in heart rate are typically not a cause for alarm. Studies have shown that up to one-third of survivors of non-severe COVID-19 experience new electrocardiographic changes and arrhythmias. Although an irregular heartbeat can be caused by other factors such as dehydration, it’s important to consult your doctor to rule out more serious Long COVID complications such as myocarditis, blood clots, and heart dysfunction.

Make sure your heart health is always in good shape by using a cutting-edge heart monitor like the Frontier X2 to monitor HRV and other vital indicators.

Frequently Asked Questions:

What are some common symptoms of Long COVID?

Some of the common symptoms of long COVID are fatigue and prolonged exhaustion, shortness of breath, cognitive difficulties such as brain fog, memory loss, and difficulty concentrating, loss of taste or smell, headaches, muscle and joint pain, and chest pain or palpitations.

Are heart palpitations a common symptom of Long COVID?

You can experience palpitations along with other persistent symptoms such as fatigue and dizziness. In most cases, they are not indicative of a serious problem.

How can I manage my heart palpitations if I have Long COVID?

Palpitations are usually harmless and do not require any treatment. You should see a doctor if they occur too often, last too long, or worsen over time. If palpitations are due to a heart problem like cardiac arrhythmias, your doctor may prescribe beta blockers to regulate your heart rhythm.

How long do heart palpitations usually last in Long COVID patients?

Heart palpitations may last for seconds, minutes, or even longer. You can feel the heart pounding or fluttering in your chest. They can occur anytime, even during rest or routine activities.

Can Long COVID cause heart damage?

Yes. Although long COVID primarily affects the respiratory system, it can damage the heart. Temporary or permanent heart damage can result from:

Insufficient oxygen supply to the heart can result in cell death and tissue damage of the heart and other organs.
COVID 19 may cause inflammation of the blood vessels and heart resulting in blood clots, reduction in blood flow to the heart and other organs.

Stress cardiomyopathy, which is caused by viral infections, damages the heart.

The COVID-19 pandemic has had a significant impact globally, with millions of cases and deaths reported in the United States alone. This Expert Consensus Decision Pathway (Ref. Link) aims to provide guidance for clinicians caring for adults with cardiac symptoms such as chest pain, shortness of breath, palpitations, and fainting after SARS-CoV-2 infection. It addresses frequently asked questions and provides practical guidance in the absence of extensive clinical trial data. In this blog, we have tried to cover what cardiologists recommend and want you to know about long COVID.

What Do We Know About Long COVID in 2023?

Long COVID refers to a set of symptoms that persist for weeks or months after the acute phase of a COVID-19 infection has resolved. These symptoms can include fatigue, brain fog, and difficulty breathing, as well as others such as muscle aches, joint pain, and sleep disturbances. It is still not fully understood why some people experience Long COVID while others do not, but it is believed to be related to the severity of the initial infection and individual differences in the immune system’s response. SARS-CoV-2 has caused more than 600 million confirmed cases, with more than 6.5 million deaths as of November 2022, more than two years into the global pandemic. Though the pathophysiology and immunological response of long COVID conditions are still being studied most of the symptoms and risk factors are identified.

Symptoms of long COVID – The three most common symptoms of COVID-19 are fatigue, shortness of breath, and cognitive dysfunction (brain fog). People may experience many other symptoms, like chest pain, fever, muscle pains, loss of smell and taste, anxiety, and depression.

Risk factors of long COVID – Identified risk factors for long-term COVID include older age; pre-existing comorbidities including obesity, cardiovascular disease, chronic lung disease, kidney disease, hypertension, and diabetes mellitus; initial disease severity; and female sex.

How long does long COVID last – It’s still unclear how long the condition can persist. It may last for a few weeks, months, or a year. More research is required to track long-term COVID patients and determine when, ideally, their symptoms will subside.

Management of long COVID condition – Multidisciplinary approach is recommended to manage long COVID patients. A person who develops long COVID conditions should seek help from primary healthcare professionals and relevant specialists. These include rehab professionals, social care workers, psychosocial workers, and mental health professionals.

Vaccination and long COVID -There is yet to learn how vaccination directly impacts long COVID conditions. Vaccination helps prevent COVID-19 infection, which is the best way to avoid post-COVID-19 infection or long COVID. The use of vaccines also reduces hospitalization and reduces mortality.

What Are The Common Heart Problems After COVID-19?

Although COVID-19 primarily affects the lungs or respiratory system, the heart can also be affected. Cardiovascular complications have been reported in both symptomatic and asymptomatic COVID-19 patients. Twenty to thirty percent of hospitalized patients with severe COVID-19 have evidence of myocardial involvement.

COVID-19 can cause temporary and lasting damage to the heart tissue leading to the following conditions:

Myocarditis and Pericarditis: Inflammation caused by the virus impacts the heart, causing Myocarditis (inflammation of the heart) and Pericarditis (inflammation of the outer lining of the heart). The coronavirus can directly infect and damage the heart muscle, or the heart muscle can be damaged and inflamed by the body’s immune response to the virus.

Arrhythmias and Heart failure: COVID-19 can directly damage the heart causing Arrhythmias and heart failure in few patients. An estimated 10 to 20 % of patients have arrhythmias related to COVID-19 infection. You can track your heart rate and ECG continuously using a heart rate monitor such as Frontier X2.

Blood clots: Severe COVID-19 infection damages the inner walls (endothelial lining) of the blood vessels and also causes blood clots throughout the body. If the blood clot obstructs the heart or brain artery, it leads to heart attack and stroke.

Stress cardiomyopathy: Viral infections subject the body to stress, which results in heart muscle disorder that impairs the heart’s ability to pump blood efficiently. As soon as the infection resolves, the stress ends, and the heart can recover.

Cytokine storm: This is a severe complication of coronavirus. In response to a coronavirus infection, the body releases a surge of proteins called cytokines, which help cells communicate with one another and fight off the invaders. This standard defensive mechanism is exaggerated in some people, leaving them vulnerable to cytokine storms. This causes inflammation of different tissues and organs like kidneys, liver, and heart. Cytokine storms can also lead to cardiac arrhythmias.

Read Cardiologist Advice on Long COVID:

Call emergency services: If you experience any heart attack or worsening symptoms related to your heart condition, call the emergency services and go to the hospital.
Continue to take your prescribed heart medications: There have been reports that certain heart medications, such as ACE inhibitors and ARBs, may make it easier for the virus to infect your body’s cells. There is currently no proof that taking these drugs increases your risk of developing COVID-19 or lessens its severity. The advantages of taking these medications, like lowering blood pressure, outweigh any potential risks.
Keep a stock of prescribed medications: Ensure you have enough heart medicine for a few weeks. If you have any concerns about your heart medications, consult your doctor or pharmacist but do not discontinue your medications on your own; seek advice from a healthcare professional.
Focus on heart-healthy lifestyle habits: Engage in regular physical activity and consume nutritious foods. Keep your stress levels as low as possible and maintain your social connections. If you have any questions about your heart or general health, contact your healthcare team.
Belief in facts over rumours: Social media and other channels are full of information about COVID-19. It can sometimes be misleading. The best available evidence is being compiled and presented by organisations like Heart & Stroke and the Canadian Cardiovascular Society. Remember to reach out to your healthcare professional if you have any doubts.

Stretching is commonly known to increase flexibility and reduce muscle stiffness, but it may also have positive effects on blood vessels. A recent study from the University of Milan found that a 12-week stretching regimen improved blood flow, reduced blood pressure, and decreased the stiffness of arteries. This is significant because good blood flow can lower the risk of heart attacks and strokes, and people with stiff arteries are more likely to have high blood pressure, high cholesterol, and inflammation.

Details on the Research on Stretching for Heart Health

The study involved 40 men and women who were divided into three groups. One group performed leg, ankle, and foot stretches 5 times a week for 40 minutes, another group only stretched one side of the body, and the third group did not stretch at all. After 12 weeks, the participants in the stretching groups showed significant improvement in the health of their blood vessels, specifically in the decreased stiffness and better function of their arteries.

The study participants used a form of stretching called passive stretching, which can be easily done at home using stretch bands or your own body weight. Although stretching can help blood vessel function, researchers noted that it may not have the same benefit on the heart muscle as aerobic exercises like running, walking or cycling. However, stretching is a good alternative when limited to home-based activities during the COVID-19 pandemic. Below is an image of the passive stretching training. (Ref. Link)

Stretching has been shown to improve heart health in several ways. Here’s how stretching has a direct impact on your heart health.

Reducing arterial stiffness: Stretching has been shown to reduce the stiffness of the arteries, which can improve blood flow and lower the risk of heart attacks and strokes.
Lowering blood pressure: Stretching can help to lower resting blood pressure, which can reduce the workload on the heart and decrease the risk of hypertension.
Lowering heart rate: Stretching has been shown to lower resting heart rate, which can improve cardiovascular fitness and decrease the risk of heart disease. Track your heart rate and ECG continuously using a heart rate monitor such as Frontier X2.
Reducing muscle tension: Stretching can help to reduce muscle tension, which can improve the efficiency of the heart and make it easier to pump blood throughout the body.

Here Are Some Tips for Safe Stretching

Breathe steadily while stretching, avoiding holding your breath.
Stretch to the point of mild discomfort, not pain.
Avoid bouncing or jerky movements, which can lead to injuries. Instead, hold the stretch steady.
Take your time, holding the stretch for 10-30 seconds before releasing and repeating the stretch.
Stretch when your muscles are warm, either at the end of a workout or after a warm bath or shower.

Stretches For Heart Health, For Beginners

The American Council on Exercise recommends these three stretches for beginners:

Standing Hip Flexor Stretch: Step forward with your left foot, keeping your right foot in place. Drop your back knee slightly, allowing your tailbone to move closer to the floor. Keep your back straight. Hold the stretch and then repeat on the other side.
Seated Head-Toward-Knee Stretch: Sit with your right leg stretched out in front of you. Bend your left leg, placing your left foot next to your right thigh. Gently fold your torso forward over your right leg. Hold the stretch and then repeat on the other side.
Reclining Figure 4 Stretch: Lie on your back with both knees bent and feet flat on the floor. Cross your right foot over your left thigh and pull your left thigh towards you. Let gravity bring your legs closer to your body to deepen the stretch. Hold the stretch and then repeat on the other side.

The European Society of Cardiology (ESC) released guidelines for sports and physical activity for individuals with heart disease in 2020. These guidelines, published in the European Heart Journal (Ref.Link), aim to promote exercise as a preventative measure for heart disease and as a means of reducing premature death in those with established heart disease.

The ESC recommends at least 150 minutes per week of moderate intensity exercise for individuals with heart disease, as well as strength-building exercise for those who are obese or have high blood pressure or diabetes. The guidelines also caution that individuals with advanced heart disease or those who are completely inactive should consult their doctor before beginning an exercise regimen. The study includes this diagram that features sporting disciplines in relation to the predominant components (skill, power, mixed, and endurance) and intensity of exercise.

Guidelines and Precautions for Exercise in Individuals with Heart Failure

Be mindful of the type of exercises you perform and avoid isometric exercises such as pushups and situps as they involve straining muscles against other muscles or an immovable object.
Consult with your doctor before engaging in outdoor exercises during extreme weather conditions such as hot, cold or humid weather, as high humidity may cause you to tire more quickly and extreme temperatures can interfere with circulation, make breathing difficult and cause chest pain. Indoor activities such as mall walking or using a treadmill may be more suitable.
Drink water regularly, but avoid overhydration, as it is important to stay hydrated, especially on hot days, but be sure to check with your doctor first.
If your exercise program has been disrupted for more than a few days, it’s essential to ease back into the routine, by starting with a reduced level of activity, gradually increasing it until you are back to your original level.
Cease your exercise routine if you experience excessive fatigue or difficulty breathing. Consult your doctor to discuss these symptoms or schedule an appointment for evaluation.
Avoid exercising if you are feeling unwell or have recently been ill. Wait until all symptoms have subsided before restarting your exercise program. If unsure, consult with your doctor first.
If you have persistent shortness of breath, rest and seek medical attention. Your doctor may adjust your medications, diet, or fluid restrictions.
Stop exercise immediately if you experience a rapid or irregular heartbeat or heart palpitations. Check your pulse after resting for 15 minutes. If it is above 120 beats per minute at rest, seek medical attention. Invest in a good heart rate monitor such as the Frontier X2 to ensure that you track your heart rate and ECG continuously while exercising.
Do not ignore any pain you may experience during exercise. If you experience chest pain or pain in any other part of the body, stop the activity immediately. Continuing to exercise while in pain may cause stress or damage to the joints.

Does cold weather impact your heart health?

Many of us are not accustomed to the physical demands of strenuous outdoor activities and may be unaware of the potential dangers of cold weather. Winter sports enthusiasts who do not take the necessary precautions may fall victim to accidental hypothermia. People with coronary heart disease often experience angina pectoris (chest pain or discomfort) in cold weather. In addition to cold temperatures, high winds, snow, and rain can also cause heat loss. Wind is particularly dangerous as it removes the layer of warm air around the body. Dampness also causes the body to lose heat more quickly than in dry conditions. With winter comes a drop in temperature that can impact your blood flow and add strain to your heart. Read on to find out more about the impact of cold weather on your heart.

How does cold weather affect your heart?

Cold weather can cause the blood vessels to constrict, making it harder for the heart to pump blood. It can cause an increase in blood pressure as well, which can put extra strain on the heart. Anyone with an existing heart condition such as hypertension, coronary artery disease, or arrhythmia are more susceptible to cold weather’s effects on the heart. Cold air can cause airway constriction in people with respiratory conditions such as asthma, bronchitis, and emphysema, which can lead to increased stress on the heart. Physical activity in cold weather can be dangerous for some people, as it may cause chest pain, shortness of breath, or other symptoms of heart disease. It’s important to check with your doctor before starting any physical activity in cold weather. People with heart conditions should be mindful of how the weather affects them and take precautions such as wearing warm clothing, staying dry and avoiding prolonged exposure to cold weather. It’s important that you are aware of the signs of a heart attack, such as chest pain or pressure, shortness of breath, and arm or jaw pain, and seek medical attention immediately if these symptoms occur.

What can you do to protect your heart in winter?

Winter can bring with it certain lifestyle choices that can put you at risk for heart disease. The temptation to stay indoors, indulge in comfort foods and consume more alcohol can all contribute to unhealthy changes in weight, cholesterol and blood pressure, which can increase your risk for heart disease and heart attacks. The cold weather may discourage outdoor activities and physical exercise, which is essential for maintaining a healthy heart. Additionally, the holiday season often comes with more social gatherings and events that can lead to overindulging in food and alcohol. It’s important to make mindful choices and maintain a balance during the winter season to ensure a healthy heart.

One way to protect your heart during the winter months is to maintain a warm living environment. Keep the room where you spend most of your time at a temperature of at least 18°C. To stay warm, wear multiple layers of clothing, including socks, jumpers and blankets. Utilising a hot water bottle or electric blanket can help keep you warm at night. To keep the heat in, try budget-friendly options like draft stoppers and insulating window coverings. Additionally, wearing a hat, scarf and gloves can help maintain your core body temperature.

Frequently Asked Questions:

What are some of the ways that cold weather can increase my risk of heart disease?

Cold weather can cause blood vessels to constrict, making it harder for the heart to pump blood. It can also increase blood pressure and put extra strain on the heart. Cold weather can also cause the heart to work harder to maintain body temperature, which can increase the risk of a heart attack.

How does cold weather affect individuals who already have heart conditions?

Individuals who have existing heart conditions such as hypertension, coronary artery disease, or arrhythmia are more susceptible to cold weather’s effects on the heart. Cold weather can also increase the risk of blood clots forming in the blood vessels, which can lead to heart attack or stroke.

What are some things that I can do to protect my heart during the winter months?

To protect your heart during the winter months, you can maintain a warm living environment, wear multiple layers of clothing, stay active indoors, and eat warming meals and healthy hot drinks to keep your body energised. If you have angina (chest pain), wearing a scarf around your mouth and nose or a face mask can help limit symptoms in cold weather.

The required amount of sleep varies from person to person, but most adults need 7-9 hours per night to function optimally. A lack of sleep can negatively impacts your physical and mental health, weaken your immune system, increase your risk of heart disease, and even shorten your lifespan. It has been found that Heart Rate Variability (HRV) is lower during sleep compared to when an individual is awake, and it decreases further as a person progresses from light to deep sleep. Additionally, research has shown that HRV is influenced by the quality and duration of sleep. Poor sleep quality and insufficient sleep have been associated with lower heart rate variability, while adequate sleep has been linked to higher HRV. Some studies have also suggested the inverse relationship, stating that HRV may also be a predictor of sleep quality, with lower HRV being associated with poor sleep quality and higher HRV being associated with better sleep quality.

(Ref.Link)

What is a Good HRV During Sleep?

The adult heart rate is typically between 60 and 100 beats per minute when at rest. As you fall asleep, your heart rate slows down to its resting rate, the body’s core temperature decreases, and other muscles relax. In deeper sleep stages your resting heart rate may decrease by about 20 to 30 percent. Heart rate variability (HRV) changes as you progress through different sleep stages. During non-rapid eye movement (NREM) sleep, overall HRV generally decreases, although the variance between individual beats can increase. In contrast, during rapid eye movement (REM) sleep, overall HRV increases while beat-to-beat changes decrease. HRV is often used as a marker of sleep quality and has been linked to various health outcomes. Poor sleep quality, high sleep onset latency, and the use of sleep medication have all been associated with higher heart rate and lower HRV. On the other hand, higher HRV during wakefulness has been tied to better sleep efficiency and overall sleep quality. Sleep deprivation and certain sleep disorders, such as obstructive sleep apnea, have also been linked to changes in HRV.

Can a lack of sleep affect HRV?

Poor sleep quality can disrupt the balance between the sympathetic and parasympathetic nervous systems, leading to an imbalance in HRV. Chronic sleep deprivation has been linked to a decrease in HRV, which may increase the risk of certain health conditions such as cardiovascular disease and diabetes. Conversely, getting enough quality sleep can improve heart rate variability and overall health. It is important to prioritize sleep and practice good sleep hygiene to help maintain healthy HRV levels.

People with insomnia experience elevated sympathetic activity both during night and day. When the sympathetic nervous system is stimulated, the heart rate increases and the HRV decreases. During sleep deprivation, this sympatho-vagal balance shifts towards sympathetic dominance. Insufficient sleep impairs the nervous system’s ability to shift into rest mode, even at night and despite feeling exhausted. HRV is used as an indicator to determine sleep quality. According to a study published in 2013, higher HRV during wakefulness is linked to better sleep quality, and lower HRV indicates inadequate sleep quality.

How to Increase your HRV During Sleep

There are several ways to increase heart rate variability (HRV) during sleep:

Practice relaxation techniques such as deep breathing, meditation, or yoga before bed to help reduce stress and improve sleep quality.
Establish a consistent sleep schedule by going to bed and waking up at the same time every day.
Avoid caffeine, alcohol, and heavy meals before bedtime, as they can disrupt sleep.
Create a comfortable sleep environment by keeping the room dark, cool, and quiet, while using a comfortable mattress and pillows.
Engage in physical activity during the day to improve sleep quality and HRV.
Avoid screens for at least an hour before bedtime, as the blue light emitted by screens can disrupt the production of melatonin, a hormone that helps regulate sleep.
Consider trying natural remedies such as melatonin or valerian root to help improve sleep quality.

HRV and Sleep: How Are They connected?

There is a complex, two-way relationship between the autonomic nervous system and sleep. The activity of the autonomic nervous system (ANS) influences both your ability to fall asleep and how well you sleep throughout the night. In turn, the quantity and quality of your sleep has an impact on how well your autonomic nervous system works in managing stress, regulating your cardiovascular activity, and regulating hormones and physiologic function. Here are some key points to understand about how the ANS functions and how HRV changes while sleeping:

During sleep, both the parasympathetic and sympathetic nervous systems are active, and their levels of activity fluctuate throughout the night.
Falling asleep is linked to increased parasympathetic activity. You will be in ‘rest and digest’ mode to drift off into sleep.
In the Non-REM (Rapid eye movement) stage, the parasympathetic system(resting) continues to dominate. Non-REM sleep is associated with higher HRV.
In REM (Rapid eye movement) sleep, the sympathetic system(stimulating) becomes more active. HRV is usually low and variable in this stage.
Disturbed sleep or waking up through the night activates the sympathetic system which raises your blood pressure and heart rate while decreasing HRV.
A typical night of 7 hours of sleep consists of 4-5 sleep cycles, with each cycle containing non-REM and REM sleep stages. During sleep, ANS activity is complex and dynamic, and HRV is continuously shifting.

Poor quality or insufficient sleep causes a decrease in HRV which can lead to increased risks for hypertension, diabetes, obesity, and other cardiovascular diseases. To ensure optimal HRV, it’s important to get enough quality sleep every night by limiting blue light exposure before bedtime, avoiding caffeine late in the day, creating a relaxing bedtime routine, keeping your bedroom cool and dark, and practicing mindfulness or meditation before bedtime. If you suspect that there may be underlying medical causes for your insomnia or difficulty sleeping through the night speak with your doctor about potential treatments or medications that might help.

Finally, pair your new understanding of how sleep affects your HRV with the use of a heart monitoring device to know exactly how you’re impacting your heart. Purchase the revolutionary Frontier X2 and be on your way to a healthier tomorrow.

Frequently Asked Questions on HRV and Sleep :

What are the effects of sleep deprivation?

Sleep deprivation activates the sympathetic nervous system (stimulating) both during sleep and daytime. This leads to irritability, stress, an increase in heart rate, and a decrease in HRV.

How can I measure my HRV?

There are several ways to measure HRV, including the following:

Wearable devices: Many fitness trackers and smartwatches have built-in HRV sensors that can measure your HRV throughout the day.
Smartphone apps: There are numerous apps available for both iOS and Android devices that use the phone’s camera or a separate chest strap to measure HRV.
ECG/EKG machines: Electrocardiograph (ECG or EKG) machines, which are used to measure the electrical activity of the heart, can also be used to measure HRV. These machines are often used in hospitals or medical offices, but there are also portable ECG/EKG devices that can be used at home.
Finger sensors: Some devices use sensors that attach to your finger to measure HRV

How can I get more sleep?

You can get more sleep by following a daily sleep routine, using a comfortable mattress, and by incorporating meditation and yoga into your daily routine.
