What is a normal heart rate?
A normal heart rate, also known as the resting heart rate, refers to the number of times the heart beats per minute while a person is at rest. It is an essential indicator of cardiovascular health and can vary depending on factors such as age, fitness level, and overall health.
In adults, a normal resting heart rate typically ranges between 60 and 100 beats per minute (bpm). However, it is important to note that there can be variations within this range based on individual factors. For example, athletes or individuals who engage in regular physical exercise may have lower resting heart rates due to their increased cardiovascular fitness. On the other hand, certain medical conditions or medications can cause an elevated resting heart rate.

According to the Mayo Clinic, a resting heart rate below 60 bpm is considered bradycardia, which may be a sign of an underlying health condition such as an underactive thyroid gland (hypothyroidism), electrolyte imbalances, or certain medications. Bradycardia can also occur in highly trained athletes with no underlying health issues.
On the other hand, a resting heart rate above 100 bpm is generally considered tachycardia. This can be caused by factors such as stress, anxiety, dehydration, fever, certain medications (e.g., decongestants or asthma medications), or medical conditions like hyperthyroidism or arrhythmias.
It is worth noting that age plays a role in determining what is considered a normal heart rate. In newborns and infants up to one year old, a normal resting heart rate can range from 70 to 190 bpm. As children grow older, their heart rates gradually decrease. For children aged 1 to 10 years, a normal resting heart rate is typically between 70 and 120 bpm. Adolescents (10 to 17 years old) usually have a resting heart rate between 60 and 100 bpm, similar to adults.
To measure your resting heart rate, you can manually check your pulse by placing two fingers (usually the index and middle fingers) on the inside of your wrist, just below the base of the thumb. Count the number of beats you feel within a 60-second timeframe or multiply the count by two if measuring for 30 seconds. Alternatively, there are various wearable devices available that can track heart rate continuously throughout the day.
It is important to remember that while a resting heart rate provides valuable information about cardiovascular health, it should not be used as a standalone diagnostic tool. If you have concerns about your heart rate or overall health, it is always recommended to consult with a healthcare professional for a comprehensive evaluation.
In conclusion, a normal resting heart rate for adults typically ranges between 60 and 100 bpm. However, individual factors such as age, fitness level, and overall health can influence this range. Monitoring your heart rate can provide insights into your cardiovascular health, but it is essential to consider other factors and consult with a healthcare professional for an accurate assessment.
