What Does Your Resting Heart Rate Reveal About Your Health?

Your resting heart rate is one of the simplest signs of your overall health. It is the number of times your heart beats each minute when your body is completely at rest. You can measure it after sitting quietly for at least five minutes or just after waking up in the morning.
For most adults, a normal resting heart rate is between 60 and 100 beats per minute. However, what is considered healthy can vary depending on your age, fitness, lifestyle, and medical conditions. Understanding your resting heart rate can help you identify changes in your health and know when it may be time to seek medical advice.

What Is a Resting Heart Rate?

Dr Deebanshu Gupta, Cardiologist at Sarvodya Hospital, Jalandhar, defines, “A resting heart rate shows how hard your heart has to work to pump blood around your body while you are relaxed. A lower resting heart rate often means your heart is working more efficiently. This is because a stronger heart can pump more blood with each beat.”

Athletes and people who exercise regularly may have a resting heart rate between 40 and 60 beats per minute. This is usually normal for them and is a sign of good heart fitness rather than poor health.

What a Low Resting Heart Rate Can Mean

A lower resting heart rate is often linked to good cardiovascular health. Regular physical activity strengthens the heart muscle, allowing it to pump blood more effectively. As a result, the heart does not need to beat as often when the body is at rest.

However, a very low resting heart rate is not always healthy. If your heart rate is below 60 beats per minute and you also experience dizziness, tiredness, fainting, or shortness of breath, you should speak to a doctor. In some cases, it could be caused by a heart condition or certain medicines.

A study by the Department of Brain Sciences at Imperial College London, both high and low heart rates are associated with potential risk of stroke.

What a High Resting Heart Rate Can Mean

A consistently high resting heart rate may suggest that your heart is working harder than normal. Many factors can cause this, including stress, anxiety, dehydration, smoking, too much caffeine, or poor sleep.

A high resting heart rate may also be linked to health conditions such as high blood pressure, an overactive thyroid, anaemia, or heart disease. If your resting heart rate regularly stays above 100 beats per minute without a clear reason, medical intervention is crucial.

Factors That Affect Resting Heart Rate

According to the American Heart Association, your resting heart rate naturally changes throughout the day. Many everyday factors can influence it, including:

• Age
• Physical fitness
• Stress and emotions
• Body temperature
• Medicines
• Smoking
• Alcohol
• Caffeine
• Hydration levels

Even climbing stairs or walking around before checking your pulse can temporarily increase your heart rate. For the most accurate reading, measure it at the same time each day while you are fully relaxed.

How to Measure Resting Heart Rate

Measuring your resting heart rate is simple and only takes a minute.

• Place your index and middle fingers on your wrist below your thumb or on the side of your neck.
• Count the number of beats you feel in 30 seconds, then multiply it by 2.
• You can also count for a full 60 seconds for a more accurate result.

Many smartwatches and fitness trackers can also measure your resting heart rate automatically throughout the day.

How to Improve Your Resting Heart Rate

If your resting heart rate is higher, healthy lifestyle changes can often help improve it over time. Here are some suggestions by Dr Gupta:

• Exercise regularly and aim for at least 150 minutes of moderate physical activity each week. A study published in the Journal of Clinical Medicine found that regular exercise significantly reduces resting heart rate.
• Eat a balanced diet rich in fruit, vegetables, whole grains, and lean protein to support heart health.
• Manage your stress. You may practice meditation and other relaxation techniques to lower stress levels.
• Besides, get enough sleep, stay hydrated, and avoid smoking to lower your resting heart rate.

When Should You Be Concerned?

A single unusual reading is not usually a cause for concern. Your resting heart rate can vary from day to day for many harmless reasons. However, you should contact a healthcare professional if you notice a sudden or lasting change in your resting heart rate, especially if it is accompanied by chest pain, fainting, severe dizziness, or difficulty breathing.

Regularly checking your resting heart rate can help you become familiar with what is normal for your body. This makes it easier to recognise changes that may need medical attention.

Final Word

Your resting heart rate provides valuable information about your overall health and heart condition. While a lower resting heart rate is often a sign of good fitness, a consistently high or unusually low rate may indicate an underlying health issue. By maintaining a healthy lifestyle and monitoring your resting heart rate from time to time, you can gain a better understanding of your body's well-being. If you notice significant changes or have concerning symptoms, it is always best to seek advice from a healthcare professional.
