A resting heart rate is one of the easiest health measurements to check, yet it can offer meaningful insight into overall well-being.

While many people pay attention to blood pressure or weight, the number of times the heart beats each minute while the body is calm can also reflect cardiovascular health and physical fitness.

Doctors say that keeping an eye on this number over time may help identify changes that deserve medical attention, especially when paired with other symptoms.

What Is a Resting Heart Rate?

According to the Mayo Clinic, a resting heart rate is the number of heartbeats per minute while a person is awake, relaxed, and not physically active.

For most adults, a healthy resting heart rate falls between 60 and 100 beats per minute (BPM). A lower resting heart rate often means the heart pumps blood more efficiently and does not need to work as hard. This is commonly seen in people with higher fitness levels. In fact, well-trained athletes may have a resting heart rate of around 40 BPM, according to the Mayo Clinic.

Although a single reading provides useful information, long-term patterns often tell a more complete story.

What Can Affect Resting Heart Rate?

Resting heart rate varies from person to person and is influenced by several lifestyle and health factors.

Age, physical activity level, sleep quality, smoking, stress, anxiety, hormonal changes, and body size can all affect heart rate. Certain medications, along with medical conditions such as cardiovascular disease, high cholesterol, and diabetes, may also cause changes in resting heart rate.

Because so many factors play a role, doctors recommend looking at overall trends instead of focusing on one isolated reading.

When Resting Heart Rate Is a Concern

A resting heart rate that remains consistently outside the normal range can sometimes point to an underlying health condition.

According to the Cleveland Clinic, even a mildly elevated resting heart rate may be linked to issues such as anemia, infections, or thyroid disorders. If the resting heart rate regularly stays above 100 BPM, it is important to discuss the findings with a healthcare provider.

Likewise, people who are not trained athletes and frequently record a resting heart rate below 60 BPM should also seek medical advice.

Medical attention becomes even more important if the unusual heart rate occurs alongside symptoms such as fainting, dizziness and shortness of breath.

These signs may indicate that additional evaluation is needed.

How to Measure Resting Heart Rate

The Mayo Clinic recommends checking a resting heart rate first thing in the morning, before beginning daily activities.

A manual reading is simple:

1. Place the index and middle fingers on the inside of the wrist below the thumb to locate the radial artery, or on the side of the neck to find the carotid artery.
2. Count the pulse for 15 seconds.
3. Multiply that number by four to calculate the heartbeats per minute.

Fitness watches and other wearable devices can also monitor resting heart rate throughout the day. While these tools are convenient, they may not always produce perfectly accurate readings.

Ways to Lower a High Resting Heart Rate

Lifestyle habits often have a direct impact on resting heart rate. According to Harvard, vigorous exercise remains one of the most effective ways to lower resting heart rate while improving aerobic fitness and increasing maximum heart rate capacity.

People who are new to exercise should gradually increase workout intensity instead of starting with demanding routines.

Other healthy habits may also help:

1. Practice stress management through meditation or yoga.
2. Get enough quality sleep each night.
3. Maintain a healthy body weight.
4. Reduce or avoid alcohol and recreational drugs, as dehydration can increase heart rate.
5. Take prescribed medications, including beta blockers, only under medical supervision, since they may lower heart rate.

Healthy lifestyle changes usually produce gradual results rather than immediate improvements.

Doctors Stress Long-Term Monitoring

Cardiologist Tamanna Singh, M.D., speaking with the Cleveland Clinic, explained that strengthening the heart takes time.

"Just like building your biceps and triceps, it takes time for your heart to become stronger."

Rather than paying attention to a single number, Dr. Singh advises tracking how resting heart rate changes over time. For example, notice whether it shifts after eating certain foods, becoming dehydrated, beginning a new exercise routine, or practicing stress management techniques.

She also emphasized the importance of seeking medical guidance if lifestyle changes fail to improve consistently high readings.

"If you notice that your heart rate is consistently over 100, mention it to your doctor, especially if you've tried making lifestyle changes and they don't seem to be working."

Dr. Singh added:

"Your resting heart rate isn't the be-all, end-all of your health, but it's definitely a marker that you should pay attention to."

A resting heart rate is not a complete measure of health, but it can serve as a useful indicator of how the body is functioning. Regular monitoring helps identify meaningful changes that may otherwise go unnoticed. Combined with healthy habits, routine medical checkups, and attention to symptoms, this simple measurement can become a valuable part of maintaining long-term heart health.
