A low resting heart rate can be completely normal, especially in individuals who are physically fit. Resting heart rate refers to the number of times your heart beats per minute when you are at rest. For most adults, a normal resting heart rate ranges from 60 to 100 beats per minute (bpm). However, for athletes or those who are physically very active, it’s not uncommon to have a resting heart rate lower than 60 bpm.
In some cases, a lower heart rate can be a sign of good cardiovascular fitness. Regular exercise makes the heart muscle stronger and more efficient, meaning it can pump more blood with each beat, and therefore, doesn’t need to beat as often.
However, if a low resting heart rate is accompanied by symptoms such as dizziness, fatigue, fainting, or shortness of breath, it may be a sign of a condition called bradycardia, which is a potentially serious condition that can result from a variety of causes such as heart disease, hypothyroidism, or certain medications, among others. Bradycardia may require medical intervention, especially if it’s caused by an underlying condition that needs to be treated.
In any case, if you have concerns about your heart rate, it’s always a good idea to consult with a healthcare professional. They can help determine whether your low heart rate is a sign of good fitness or if it’s a symptom of a more serious health issue.
