When you are infected with a virus like COVID-19, your immune system generates antibodies to combat it. Your immune system can also learn to produce antibodies in a safe manner through vaccination. Once an individual has developed the antibodies to a specific disease they provide some protection against that disease. Even if you do contract the disease, having antibodies can prevent you from becoming gravely ill because your body already has some experience fighting it. The duration of this protection can vary by disease, by individual, and a number of other variables.
What exactly are Antibodies? Antibodies are proteins that neutralise specific viruses, bacteria, or other foreign substances by recognising and binding to them. As research in this field is ongoing, there is no definitive knowledge on how long COVID-19 antibodies remain in the body. That being said, it is believed that antibodies against COVID-19 can remain in the body for a few months to over a year.
In the early days of the pandemic, a study published in “The Lancet” found that antibodies lasted for 3 months and declined in the 4th month in recovered COVID-19 patients. Subsequent evidence suggested that natural immunity could last for up to eleven months. Recent research suggests that adults infected with the SARS-CoV-2 virus develop antibodies that circulate in the body for nearly 500 days (approximately 16 and a half months).
It is important to note that these studies were conducted on a small number of patients, and more research is needed to determine the duration of time that antibodies remain in the body. Additionally, the presence of antibodies does not necessarily mean a person is immune to the virus. The level of antibodies required to provide immunity is not yet known, and some individuals may still be susceptible to reinfection even if they have antibodies.
Other factors such as a person’s age, overall health, and the severity of their initial COVID-19 infection may also play a role in the duration of time that antibodies remain in the body.
COVID-19 immunity can be acquired through vaccination, natural infection, or a combination of both. Antibodies also known as Immunoglobulins are produced by the immune system in response to the SARS-CoV-2 virus or COVID-19 vaccines.
It is unknown how long immunity to COVID-19 lasts, and it may depend on whether a person has natural immunity or immunity from vaccination.
The duration of natural immunity may exceed a year, but more research is required to comprehend vaccine-based immunity. The Initial research suggests that the Pfizer and Moderna COVID-19 vaccines provided protection for approximately four months after a booster dose. Nevertheless, despite being fully vaccinated, a few individuals continued to fall ill. Government agencies recommend a vaccination booster dose for individuals over the age of 50. Even with booster doses, breakthrough infections were still possible with Omicron sub variants. Researchers have discovered that immune cells known as T cells respond to the Omicron variant six months after vaccination. This suggests that individuals may have protection against SARS-CoV-2 for an extended period of time.
It is likely that hybrid immunity, which is a combination of natural and vaccine-based immunity, offers greater protection. A study conducted in 2022 revealed that hybrid immunity can provide protection for more than a year.
Various Sars-CoV-2 strains were found throughout the pandemic. BA.5 is the most common strain found as of November 2022. According to a study published in 2022, previous COVID-19 infections or vaccinations did not provide as much protection against the new variants as they did against the original strain of SARS-CoV-2. Omicron can pass undetected by antibodies, even if a person has previously been infected with or vaccinated against COVID-19. This is called immune evasion. Even though the virus may evade neutralising antibodies, COVID-19 vaccines can still protect against severe disease caused by Omicron.
While antibodies can provide protection against COVID-19 reinfection, the effectiveness of this protection may vary depending on the individual and the specific variant of the virus they were infected with. The emergence of new variants of the COVID-19 virus has raised concerns about the effectiveness of current vaccines and antibodies in protecting against reinfection. However, the current vaccines have shown to be helpful in fighting against the variants, even if the protection is not 100%. The Booster doses have been developed to increase the immunity against the new variants.
The duration of time that COVID-19 antibodies stay in a person’s system is not yet fully understood. Studies have shown that the presence of antibodies can vary greatly among individuals, and may decline rapidly in the first three months after infection. However, some individuals have detectable antibodies for up to six months after infection. Further research is needed to understand the duration of time that COVID-19 antibodies stay in a person’s system, and the factors that may affect this duration. Additionally, having COVID-19 antibodies does not necessarily mean that a person is immune to the virus.
Finally, as we learn more and more about the long term effects of Covid, the more we recognise its impact on different bodily systems. Purchase the Frontier X2 smart heart monitor to keep tabs on the most important heart health metrics so that you can make sure your heart is healthy, whether or not you had Covid.
The duration of immunity following COVID-19 vaccination is still being studied, but early data suggests that the immunity provided by the vaccines is long-lasting. Studies have shown that the Pfizer-BioNTech and Moderna vaccines provide high levels of protection for at least four months after the booster dose.
If you are infected with BA.4 or BA.5, they do not boost the immune system and you can get sick with COVID-19 back-to-back.
Many people don’t develop immunity after contracting an Omicron subvariant illness. While they are ill, people may continue to produce antibodies. However, immune evasion may prevent those antibodies from detecting a subsequent Omicron infection.

Most people infected with COVID 19 recover within a few days or weeks. Others may experience post-COVID conditions for as long as several months after infection. This condition is known as “post-COVID-19 syndrome”, “long COVID-19”, “post COVID conditions”, or “long-haul COVID-19”. The individuals who suffer from this condition are known as “long haulers.” Post-COVID-19 syndrome is characterised by a variety of new, recurring, or persistent symptoms that individuals experience more than four weeks after contracting COVID-19. For some people the post-COVID-19 syndrome can last for months, years, or even result in disability.
People with post-COVID conditions may experience a variety of symptoms that may persist for weeks, months, or even years following being infected. Post COVID conditions are not the same for everyone – people are likely to experience different combinations of symptoms for different lengths of time. Although the most common symptoms are physical symptoms like fatigue and cough, new research says that long COVID condition has mental health effects
Recent research has established a connection between Long COVID and cardiovascular issues. COVID-19 has been observed to harm the heart muscle in some individuals, which can lead to inflammation and the development of heart disease. Long COVID patients have been found to have higher rates of abnormal blood clotting, increasing their risk of heart attack and stroke.
Additionally, Long COVID patients have been found to have higher rates of myocarditis, an inflammation of the heart muscle, and pericarditis, an inflammation of the lining around the heart. These conditions can cause chest pain and other heart disease symptoms, and can increase the risk of heart attack.
Individuals who had recovered from COVID-19 displayed significant increases in 20 cardiovascular issues within one year of being infected. For instance, they were 52% more likely to have had a stroke in comparison to the control group, meaning that out of every 1,000 individuals studied, there were 4 additional people in the COVID-19 group who experienced a stroke.
The risk of heart failure increased by 72%, or 12 additional people in the COVID-19 group per 1,000 studied. Hospitalization elevated the probability of future cardiovascular complications, however, even those who avoided hospitalization were still at a higher risk for several conditions. (Ref. Link)
Post-COVID conditions and the number of people who experience it are still the subject of ongoing research. The percentages reported by individuals with long COVID have varied widely. This discrepancy in numbers is because the condition is still new and scientists are still learning about it.
Anyone who is infected with COVID can develop long COVID. However, these factors make people more likely develop long COVID:
We are still understanding the long term effects of COVID, and recent research is suggesting that its impact on our cardiovascular system is significant. The best way to ensure that you heart is functioning properly is by monitoring it as closely as possible. Use a smart heart monitor like the Frontier X2 to gain access to a variety of important heart health metrics that tell you everything you need to know to stay heart healthy!
Long COVID usually develops 4 weeks or later after COVID infection. If you notice symptoms like fatigue, shortness of breath, loss of smell, body aches, brain fog, or cough a few weeks after COVID infection, you are most likely to have long COVID.
While the exact duration of long Covid is unknown, the majority of long-haulers recover from COVID within 3 months of the onset of their initial COVID-19 illness. Others, however, may experience symptoms well beyond three months.
Long-term COVID cannot be cured with a single medication or treatment. Long-term COVID symptoms differ between individuals. There are treatments that may assist in alleviating some of the symptoms. On the basis of the symptoms, your physician may recommend physiotherapy or psychotherapy. If the symptoms are severe, the patient will be referred to the appropriate specialist.

Stress is a common and unavoidable part of life, but when it becomes chronic it can have a significant impact on one’s overall health and well-being. A key area of concern is the link between stress and heart disease. Studies have shown that stress can be a major contributing factor to the development of heart disease, and the relationship between the two is complex and multifaceted. A study conducted in 2021 involving 118,706 individuals from 21 countries without a history of heart disease found that high stress was associated with an increased risk of:
Stress affects lifestyle behaviours.
Stress causes Inflammation:
Stress increases Blood pressure
Stress can lead to Heart attack & Stroke:
Furthermore, stress can also affect the cardiovascular system by promoting the formation of blood clots, which can lead to a heart attack or stroke. Stress can cause the blood vessels to constrict, which can increase the risk of blood clots. Stress can also increase the levels of certain substances in the blood that promote the formation of blood clots.
Stress affects sleep:
Stress can be a major contributing factor to the development of heart disease. The relationship between stress and heart disease is complex and multifaceted, and it involves a number of different mechanisms. However, it is important to note that not all stress is bad, and a certain amount of stress can be beneficial for overall health. Therefore, it is important to learn to manage stress in a healthy way, such as through exercise, mindfulness, and other stress-reduction techniques. Additionally, it is important to be aware of the early warning signs of heart disease, such as chest pain, shortness of breath, and fatigue, and to seek medical attention if you experience any of these symptoms.
Finally, the best way to know that your heart is protected from life’s stressors is by monitoring it as closely as possible. Purchase the revolutionary Frontier X2 smart heart monitor so you can keep tabs on a number of key heart health metrics. Stay informed so your heart can stay healthy.

According to the Centres for Disease Control and Prevention (CDC), heart disease is the leading cause of death among men and women in the United States. However, both the causes and effects of heart disease vary by sex. For example, men and women may have different responses to stress, a significant risk factor for cardiac issues. Several studies suggest that the association between psychosocial stress and Coronary heart disease (CHD) may be stronger in women than in men.
According to new research, women are exposed to many psychological stressors that men are not exposed to. Another study released by the American Psychological Association found that women are more likely to document higher levels of stress and associated symptoms than men are.
One study, conducted by Drexel University (ref. Link ) in the United States, discovered a 21% increased risk of coronary heart disease in women who experience high levels of stress from both their job and their social relationships.
This article provides a brief overview of why stress can increase the risk of heart disease for women, and what can be done to avoid this.
According to the American Psychological Association’s “Stress in America” survey, Women are likely to report higher levels of stress than men. A scientific statement published in Circulation by the American Heart Association (AHA) states that when women are exposed to stressors, their risk of heart attack is significantly higher than that of men in a similar situations. When one is exposed to a stressor, the “fight-or-flight” response is activated, thereby triggering a cascade of hormones and chemicals that increase the heart rate, blood pressure, and decrease HRV. If this response is triggered at an excessive rate, it can lead to heart disease.
The most common symptom of heart attack that men experience is chest pain. On the other hand, women often describe a heart attack as feeling pressure in the chest rather than pain.
Other symptoms of Heart Attack that women commonly experience:
Emotional stress may play a role in the onset of heart attack symptoms for women. As a woman’s heart attack symptoms may differ from a man’s, women may be diagnosed with heart disease less frequently than men. Women are more likely to suffer a heart attack without a severe artery blockage (nonobstructive coronary artery disease).
Always seek medical help if you have difficulty managing stress.
Here are few activities that can help you tackle stress :
It’s important to know how stress impacts heart disease especially in women. Stress can also make you tempted to indulge in unhealthy habits like binge eating, excess consumption of alcohol, or smoking. This may lead to obesity, high blood pressure, or an increase in cholesterol levels, all of which are the risk factors for heart disease. Try to include healthy habits like exercise and meditation to manage stress.
Understanding the impact of stress on women’s heart health is the first step. The next step is to know exactly how you’re impacting your heart by using a smart heart monitor that gives you detailed, accurate data on your cardiac functioning.. Purchase the revolutionary Frontier X2 and be on your way to a healthier tomorrow.
A: Some common risk factors for heart disease in women include smoking, high blood pressure, high cholesterol, diabetes, a family history of heart disease, and being overweight or obese.
A: Heart disease symptoms in women can be more subtle and may include fatigue, shortness of breath, and upper body discomfort. Some women may not experience any chest pain at all during a heart attack.
A: Signs of a heart attack in women can include chest pain or discomfort, upper body discomfort (such as pain in the arms, back, neck, jaw, or stomach), shortness of breath, sweating, nausea or vomiting, and lightheadedness or dizziness.
A: Yes, heart disease can be prevented through lifestyle changes such as eating a healthy diet, exercising regularly, maintaining a healthy weight, and not smoking. Regular check-ups with your healthcare provider and taking prescribed medications as directed can also help to prevent heart disease.
A: If you think you’re having a heart attack, call your local emergency number immediately. Do not drive yourself to the hospital. Chew and swallow an aspirin, unless you are allergic to aspirin or have been told by your doctor never to take aspirin.

Atrial fibrillation (AFib) is the most common type of arrhythmia and it occurs when the upper chambers of the heart (the atria) beat irregularly. It’s a serious condition that can increase the risk of stroke and heart failure. While medications and other medical treatments are essential in managing AFib, nutrition also plays a crucial role. We will explore the role of nutrition in managing AFIB and discuss ways to make dietary changes that can help to reduce symptoms and improve overall heart health.
Eating a healthy, balanced diet is important for managing AFib and maintaining overall heart health. This involves eating a variety of nutrient-dense foods, such as:
Research shows that a Mediterranean-style diet, rich in fruits, vegetables, whole grains, and healthy fats, may be beneficial in reducing the risk of Afib. Additionally, it’s important to limit the intake of processed foods, high-caloric foods, foods high in saturated and trans fats, and added sugars.
A study published in the journal of American Heart Association found that high salt intake is associated with an increased risk of AFIB. This associate has been made given that a high intake of salt can lead to high blood pressure, which is a major risk factor for the condition.
The American Heart Association recommends consuming no more than 2,300 mg of sodium per day, but ideally, adults should aim to consume no more than 1,500 mg per day. This can be achieved by limiting the intake of processed foods and adding less salt to meals.
Alcohol consumption has also been linked to atrial fibrillation. The 2020-2025 Dietary Guidelines for Americans recommends that men should have no more than two drinks per day and women should have no more than one drink per day. It’s also important to keep in mind that alcohol can interact with some medications used to treat AFib, so it’s important to speak with a healthcare provider before making any changes to alcohol consumption. A Norwegian HUNT Study (Ref. Link) found that excessive consumption of alcohol increases the risk of AFib.
Some dietary supplements have been found to be beneficial in managing AFIB, but it is important to keep in mind that supplements are not regulated by the FDA and may not be safe for everyone. Some supplements that may be beneficial for AFIB include:
It is important to consult with a healthcare professional before taking any dietary supplements, as they can interact with medications and other treatments.
To sum up, Atrial fibrillation is a serious condition that can increase the risk of stroke and heart failure. While medications and other medical treatments are essential to managing AFIB, nutrition also plays a crucial role. Eating a healthy, balanced diet that is low in sodium and alcohol can help to reduce symptoms and improve overall heart health. Additionally, certain dietary supplements may also be beneficial in managing AFIB.
Finally, pair your new dietary knowledge 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.
Proper nutrition can help manage AFIB by maintaining a healthy weight, controlling blood sugar levels, and providing the necessary nutrients for heart health. Eating a diet high in fruits and vegetables, lean protein, and whole grains, and low in processed foods, saturated fats, and added sugars, can help reduce the risk of AFib and its complications.
People with AFib should limit their intake of caffeine, alcohol, and processed foods, as these can all trigger or worsen AFib symptoms. Some supplements, such as vitamin E and niacin, may also interact with blood thinning medications and should be used with caution. Excessive dosage of Omega 3 fatty acids can also trigger AFib. It is best to consult your doctor before starting any new supplements.
The Mediterranean diet and the DASH (Dietary Approaches to Stop Hypertension) diet are both recommended for managing AFIB, as they focus on whole foods and emphasise fruits, vegetables, lean protein, and whole grains. These diets have been shown to reduce the risk of AFIB and its complications.

Arrhythmia is a condition characterised by an irregular or abnormal heart rhythm. This can include your heart beating too fast, too slowly, or unevenly. An arrhythmia can be caused by a variety of factors, including heart disease, genetics, and lifestyle factors. A study published in the Journal of American heart Association, found that people with atrial fibrillation (a type of arrhythmia) have a higher risk of stroke and death from cardiovascular causes compared to those without the condition.
We will explore the connection between arrhythmias and heart health, and discuss ways to prevent, treat, and live with this condition.
There are several different types of arrhythmias, each with its own set of symptoms and causes. These are the most common types of arrhythmias:
Atrial fibrillation: This is the most common type of arrhythmia, and occurs when the upper chambers of the heart (the atria) beat irregularly.
Symptoms of atrial fibrillation include
Ventricular tachycardia: This type of arrhythmia occurs when the lower chambers of the heart (the ventricles) beat too quickly.
Symptoms of ventricular tachycardia include
Bradycardia: This type of arrhythmia occurs when the heart beats too slowly.
Symptoms of bradycardia include
There are several factors that can increase a person’s risk of developing arrhythmias. These include:
There are several steps that can be taken to prevent arrhythmia. These include:
Treatment for arrhythmia will depend on the type of arrhythmia and the underlying cause. Treatment options can include:
To sum up, Arrhythmia is a condition characterised by irregular or abnormal heart rhythm. It can be caused by a variety of factors, including heart disease, genetics, and lifestyle factors. Understanding the connection between arrhythmia and heart health is important in order to prevent and treat this condition. By maintaining a healthy lifestyle, managing blood pressure, managing heart disease, and monitoring for symptoms, people can reduce their risk of developing arrhythmia. Treatment options for arrhythmia include medications, electrical cardioversion, catheter ablation, and implantable devices. It is important to work with a healthcare provider to determine the best course of treatment for your specific case.
Monitoring your heart health is the best way to ensure that you do not develop major complications. The best way to monitor your heart on a daily level is by using a smart heart monitor like the Frontier X2, which gives you access to a variety of important heart health metrics that tell you how well/poorly your heart is functioning. So, purchase the Frontier X2 and be on your way to a healthier tomorrow!
Arrhythmia is a condition characterised by irregular or abnormal heart rhythm. This can include a too-fast(Tachycardia) or too-slow(bradycardia) heartbeat, or a heartbeat that is uneven( Atrial Fibrillation).
Arrhythmia can be caused by a variety of factors, including heart disease, genetics, high blood pressure, smoking, obesity, and certain medications.
Symptoms of arrhythmia can vary depending on the type of arrhythmia and the underlying cause. Common symptoms include heart palpitations, shortness of breath, chest pain, light-headedness, fainting, fatigue, weakness, and dizziness.
Arrhythmia is typically diagnosed through a physical exam, a review of symptoms, and tests such as an electrocardiogram (ECG) or wearable smart heart tracker.
Arrhythmias can be serious and even life-threatening in some cases. Certain types of arrhythmias, such as ventricular tachycardia, can lead to cardiac arrest if not treated. It is important to seek medical attention if you experience symptoms of arrhythmia.
Aptly named, a heart-healthy diet is essential for maintaining a healthy heart and preventing heart disease. One of the key components of a heart-healthy diet is adequate protein intake. Protein is important for maintaining muscle mass, supporting healthy bones, and helping the body to repair and rebuild tissues. However, many people think that meat is the only source of protein, which is not the case.
A study published in the Journal of the American College of Cardiology (Ref. Link) found that a vegetarian diet was associated with a lower risk of heart disease relative to a non-vegetarian diet. The study also found that vegetarians had lower blood pressure and lower levels of LDL cholesterol, which is the “bad” cholesterol that can contribute to the development of heart disease.
Therefore, there is value in choosing plant-based protein sources more often than animal-based ones. Compared to other types of high protein foods, plant-based protein foods contain more fibre, less saturated fat, and are considered heart healthy.
There are many vegetarian sources of protein that can be included in a heart-healthy diet. We will explore some of the best vegetarian protein sources for a heart-healthy diet
Legumes are an excellent source of protein for vegetarians. They are also a good source of fibre, which helps lower cholesterol levels and promote heart health. Some examples of legumes include lentils, black beans, chickpeas, and kidney beans. These can be added to soups, salads, and stews to boost protein content. Legumes are also a good source of iron, which is important for maintaining healthy blood cells.
Nuts and seeds are another good source of vegetarian protein. They are also a good source of healthy fats, which (like legumes) can help to lower cholesterol levels and promote heart health. Some examples of nuts and seeds that are high in protein include almonds, peanuts, sunflower seeds, and pumpkin seeds. These can be added to salads, yogurt, or eaten alone as a snack. Nuts and seeds are also a good source of magnesium, which is important for maintaining healthy blood pressure.
Tofu and tempeh are both made from soybeans and are great sources of vegetarian protein. Tofu is a good source of calcium, which is important for maintaining healthy bones. Tempeh is a fermented soy product that is high in protein and is a good source of probiotics, which can help to promote a healthy gut. Both tofu and tempeh can be added to soups, stir-fries, and salads to boost protein content.
Quinoa is a grain that is high in protein and is considered a complete protein, which means it contains all of the essential amino acids. It is also a good source of fibre, which helps lower cholesterol levels and promotes heart health. Quinoa can be used as a substitute for rice or pasta in dishes and can also be added to salads and soups.
Eggs are a great source of protein for vegetarians. They are also a good source of vitamins and minerals, including vitamin D, which is important for maintaining healthy bones. Eggs can be used in a variety of dishes, including omelettes, frittatas, and quiches.
One of the key components of a heart-healthy diet is adequate protein intake. However, many people think that meat is the only source of protein, which is not the case. There are many vegetarian sources of protein that can be included in a heart-healthy diet. Legumes, nuts, and seeds, tofu, tempeh, quinoa, and eggs are all great sources of vegetarian protein. If you do not want to eat meat, including these foods in your diet ensures that you are getting enough protein to support a healthy heart.
Finally, pair your new knowledge on vegetarian protein options 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.
Keep your heart health in top form by utilizing a smart heart monitor such as the Frontier X2, which can track HRV and other essential metrics.
Yes, a well-planned vegetarian diet can provide all the necessary nutrients, including protein, for a healthy heart. It is important to include a variety of protein sources and to make sure you are getting enough protein overall.
Legumes and nuts are great sources of protein and also contain other beneficial nutrients such as fibre and healthy fats, which can keep heart healthy.
As long as a vegetarian diet is well-planned and balanced, it can be a healthy option for promoting heart health. However, if a vegetarian diet is not planned properly, it can lead to deficiencies in certain nutrients such as vitamin B12 and iron.
The recommended daily intake of protein is different for everyone and depends on factors such as age, sex, and physical activity level. However, a general guideline is to aim for 0.8 grams of protein per kilogram of body weight per day. This can be achieved through a combination of different protein sources throughout the day.

Heart rate variability (HRV) is a measure of the fluctuation in intervals of time between consecutive heartbeats, as determined by electrical signals from the heart. It is calculated by analysing the variations in the time between beats and is usually measured in milliseconds. The amount of time that elapses between two consecutive beats is known as an RR interval. In general, a higher HRV indicates better overall cardiovascular health, while a lower HRV could be indicative of illness or stress.
HRV is influenced by the activity of the sympathetic and parasympathetic nervous system, which controls the heart rate. HRV has been shown to be a useful indicator of overall heart health and can provide insight into the balance between the sympathetic and parasympathetic nervous system. Low Heart Rate Variability is associated with increased risk of heart health or cardiovascular disease and mortality, while high HRV is associated with better heart health and overall well-being.
Your Autonomic Nervous System regulates the heart function. Autonomic nervous system (ANS) is divided into 2 main parts: your Sympathetic Nervous System and your Parasympathetic Nervous System. The overall ANS activity on the heart is the net balance between the sympathetic and parasympathetic activity.
Sympathetic system – The Sympathetic nervous system, or your “fight-or-flight” response, is activated in emergency situations. When the sympathetic nervous system is stimulated, it increases one’s heart rate and blood pressure, and lowers HRV.
Parasympathetic system – Parasympathetic nervous system, or “rest or digest“ mode, is the relaxation response. This helps balance the sympathetic nervous system after the “flight or fight response” has been activated. It slows down the heart rate and lowers the blood pressure, while increasing HRV.
It’s important to note that HRV should not be used as a sole indicator of heart health, and should be considered in conjunction with other markers and clinical examinations. Consult with your doctor if you have any concerns about your heart health.
HRV is typically measured by an electrocardiogram (ECG). The most commonly used method for measuring HRV is to calculate the standard deviation of the normal-to-normal (NN) intervals, which are the intervals between consecutive R-peaks (the peak of the QRS complex) in the ECG. Another commonly used method is to calculate the root mean square of successive differences (RMSSD) of the NN intervals.
Outside the medical setting, HRV can be measured using fitness tracker devices or chest strap heart monitors like the Frontier X2. Devices like these track your pulse over time and calculate the variations between each beat in order to determine an average HRV score for you. The higher the score, the healthier your cardiovascular system is.
A study in 2017 (ref. link) revealed that chest strap based fitness trackers often produce more accurate results than the smartwatches. Therefore, outside of hospital settings, chest strap devices are the preferred method of measuring heart rate and HRV. Click here to find out more about the Frontier X2 smart heart monitor that will help you track your heart health effectively.
There is some evidence that HRV can be improved through various interventions.
These are the lifestyle habits to improve HRV :
HRV is an important indicator of the health of the autonomic nervous system, and is thought to reflect the balance between the sympathetic and parasympathetic branches of this system. Low HRV has been associated with several health risks, such as an increased risk of heart disease, diabetes, and hypertension. It has also been linked to an increased risk of death in both healthy individuals and those with cardiovascular disease. In contrast, high HRV has been associated with better cardiovascular health and a lower risk of death. Factors that can affect HRV include stress, physical activity, sleep, medications, and mental health.
Get access to HRV data as well as many other significant heart health related metrics by using a smart heart monitor like the Frontier X2.
HRV is an indicator of the overall health of the heart and cardiovascular system. A healthy HRV indicates a balance between the sympathetic and parasympathetic nervous systems, which control heart rate and blood pressure. Low HRV may be an indication of stress or poor cardiovascular health.
HRV can be measured through various methods such as electrocardiography (ECG), heart rate monitors, and other wearable devices. ECG is the most accurate method, but it is also the most invasive. Heart rate monitors and wearable devices can also provide accurate HRV measurements but may not be as precise as ECG.
Outside the medical setting, you can measure HRV by chest strap heart monitors, fitness trackers, and other smart phone apps.
There are several ways to improve HRV, including regular physical activity, stress management, and healthy eating. It is also important to get enough sleep and avoid smoking and excessive alcohol consumption.
HRV can be used as an indicator of heart disease risk. Low HRV has been linked to an increased risk of heart disease and other cardiovascular conditions. However, HRV should not be used as the sole indicator of heart disease risk, and other factors such as blood pressure, cholesterol, and family history should also be taken into consideration.
There are several ways to improve HRV, including regular physical activity, stress management, and healthy eating. It is also important to get enough sleep and avoid smoking or excessive alcohol consumption.

Water plays a vital role in the human body, making up 60-70% of an individual’s weight. It is crucial for various bodily functions such as digestion, absorption, transportation, elimination, and circulation of biomolecules, as well as maintaining body temperature. When dehydrated, the heart has to work harder to pump blood, which can strain the heart and increase the risk of heart disease.
As the temperatures soar, staying hydrated becomes crucial for optimal heart health. Proper hydration helps the heart pump blood quickly through the vessels to the muscles and enables muscles to function efficiently. According to John Batson, M.D., a sports medicine physician and American Heart Association volunteer, “When the body is well hydrated, the heart doesn’t have to work as hard.”
This goes hand-in-hand with research presented at the European Society of Cardiology Congress 2021 (Ref. Link). It stated that maintaining proper hydration throughout one’s life can decrease the risk of developing heart failure. The author, Dr. Natalia Dmitrieva of the National Heart, Lung, and Blood Institute (NHLBI), emphasized that “good hydration throughout life may decrease the risk of developing left ventricular hypertrophy and heart failure.” In summary, the study suggests that keeping the body hydrated can slow down or even prevent the changes in the heart that lead to heart failure.
We have outlined below the five ways in which drinking water can have an impact on your heart.
Being well-hydrated means having adequate water in the body to support its functions. The amount of water a person needs varies based on climate, clothing, and exercise intensity and duration. People who sweat heavily or have certain medical conditions, such as diabetes or heart disease, may need to drink more water. Medications that act as diuretics can also cause the body to lose more fluid, making you reach out for a glass of water more often.
Thirst is not always the best indicator of hydration needs. A better way to gauge hydration levels is by looking at the color of your urine. Clear and pale urine is a sign of good hydration, while dark urine indicates a need to drink more fluids.
To determine the specific amount of water needed, one can weigh themselves before and after exercise to see how much water loss occurs through perspiration. It’s best to replenish a pint of water for every pound of sweat lost. Athletes training in hot weather may lose 5 pounds or more of sweat during practice, so it is essential to stay hydrated. Not sweating during physical activity can be a warning sign of dehydration and heat exhaustion. Together with hydration, we recommend a Smart Heart Monitor such as the Frontier X2.
Drinking enough water can help lower your risk of heart disease by reducing the risk of a heart attack. Adequate hydration can also help lower blood pressure and improve cardiovascular health by improving blood flow, reducing inflammation, and preventing heart failure.
The amount of water you should consume for heart health varies from person to person, depending on factors such as age, sex, weight, and activity level. However, a general guideline is to drink at least 8 cups (64 ounces) of water daily. Pay attention to your body’s thirst signals and urine color. Pale and clear urine indicates good hydration, while dark urine indicates dehydration. Drinking more water in hot weather or when sweating a lot (working out, running, or cycling) is also vital.
When it comes to heart health, plain, clean, and safe drinking water should be your go-to. It’s also important to be mindful of drinking water that contains added sugars, artificial sweeteners, or other chemical additives. These can be detrimental to heart health.

A mild or moderate COVID-19 infection lasts approximately two weeks in most patients. In others, however, the long-term effects of COVID-19 can cause persistent health issues even after their fever and cough have subsided, and they no longer test positive for the illness. Sometimes symptoms may last longer. This condition is known as ‘long COVID’ or ‘post-COVID-19 syndrome’ and refers to the long-term effects of COVID-19 infection that can last from weeks to months. The people who experience long COVID are called ‘long-haulers’ and include individuals with both mild and severe cases of COVID-19. The majority of long-haulers test negative for COVID-19 despite persistent symptoms.
Research (ref. link) indicates that 50 to 80% of people who recover from COVID-19 experience at least some lingering side effects three months after coronavirus infection. Data shows that 7.5% of adults in the U.S., or about 1 in 13 people, will experience long COVID symptoms. According to British researchers (ref. link), about 10% of COVID-19 survivors that are hospitalized can have long-term health issues. Women reported symptoms at higher rates than men. They made up 72% of the COVID-19 long-haulers.
Long COVID patients should monitor their heart health because COVID-19 has been shown to have potential cardiovascular effects, such as heart muscle inflammation (myocarditis) and blood clots. Additionally, the prolonged stress and fatigue associated with long COVID can also have an impact on heart health. By monitoring heart health, long COVID patients can detect and address any potential issues early on, which can help prevent further complications and improve overall recovery. This can include monitoring blood pressure, cholesterol, and other cardiovascular risk factors and being aware of any symptoms such as chest pain or shortness of breath. Track your heart health with a Smart Heart Monitor like the Frontier X2.
People with long COVID have a wide range of symptoms that vary from person to person. They can last weeks, months, or even years after infection. According to a survey by Dr. Natalie Lambert in a California study, long COVID symptoms can appear at regular intervals, often a week or ten days apart. These are the most commonly reported symptoms of post-COVID-19 syndrome:
It can be challenging to distinguish between COVID-19 and other causes of symptoms, such as a pre-existing medical condition. It is also unclear if the post-COVID-19 syndrome is unique to COVID-19. Some symptoms resemble chronic fatigue syndrome and other diseases that develop after infections. According to the ONS (Office for National Statistics (ref. link)), the most common long Covid symptoms reported were:
Some people may be more likely to be affected by long COVID than others like:
There is no diagnostic test that is universally accepted as a definitive measure for identifying people with long-term symptoms of COVID-19. Consult your physician if you experience any of the long-lasting COVID symptoms. Your doctor may suggest a few tests to determine how long COVID affects you.
These tests could include:
Your physician handles medical management like
o Respiratory- if suspected pulmonary embolism or pneumonia.
o Cardiology – if suspected MI, myocarditis, or palpitations.
o Neurology- if suspected neurovascular changes.
Older individuals, women, and those with a more severe Covid-19 infection (five or more symptoms in the first week) are more likely to develop long Covid.
There is currently no evidence to suggest that long COVID is contagious, as it is not caused by the virus but rather by the body’s response to it.
If you have long COVID, you might test positive, usually on a PCR test. This is because the PCR test detects the virus’s genetic material and not necessarily the presence of a live virus. However, it’s also possible that you would test negative on a PCR test if you have long COVID, as the viral load in your body may be low enough that the test does not detect it.
Recovery from long COVID can vary. Some symptoms may improve rapidly, while others may persist longer. Your physician can help you manage your symptoms effectively. The recovery time for long COVID can vary significantly from person to person. Some people may recover within a few weeks or months, while others may experience symptoms for much longer. Some symptoms may be chronic and persist for months or even years.
