Introduction
A resting heart rate between 60 and 100 beats per minute during deep sleep is considered normal. Since blood circulation slows down during sleep, as long as the heart rate remains within the normal range, it is generally a normal condition and there is no need for concern. However, if the heart rate is too fast or too slow, it may indicate an abnormality, and a detailed medical evaluation at a hospital should be sought promptly. Treatment should be selected based on the underlying cause.
The heart rate during deep sleep is considered normal if it ranges between 60 and 100 beats per minute. During sleep, blood circulation slows down, so as long as the heart rate remains within the normal range, this is a normal condition and there is no need for concern.
Heart rate refers to the number of heartbeats at rest. In healthy individuals, the normal resting heart rate is 60 to 100 beats per minute. Heart rate can vary due to factors such as age, emotions, and gender. For example, children generally have faster heart rates than adults, women tend to have faster heart rates than men of the same age, and older adults typically have slower heart rates than younger people—these are all normal physiological variations. Heart rate also differs between physical activity and sleep; during activity, when blood circulation increases, heart rate naturally rises.
During sleep, metabolic activity slows, leading to a decrease in heart rate. As long as the heart rate stays within the normal range, there is no cause for worry. However, if the heart rate falls below 60 beats per minute during sleep and is accompanied by disrupted breathing or sudden awakening, a medical evaluation including an electrocardiogram (ECG) should be conducted to establish a diagnosis and initiate appropriate treatment.
In addition, abnormally fast or slow heart rates are considered abnormal conditions and require prompt medical evaluation. Detailed examinations should be performed at a hospital to determine the underlying cause, followed by appropriate treatment based on the diagnosis.
