Introduction
In general, moderate running at night does not affect sleep. However, intense exercise may increase blood flow too rapidly, leading to overexcitement and consequently disrupting sleep. Running moderately in the evening can release endogenous substances such as endorphins, promoting physical relaxation. This helps alleviate emotional tension and anxiety, thereby facilitating better sleep.
Generally speaking, moderate evening running does not affect sleep. However, engaging in intense exercise may cause excessively rapid blood flow, leading to overexcitement and consequently disrupting sleep. The details are as follows:
1. No negative impact
Moderate evening running can release endogenous substances such as endorphins, helping the body to relax. This reduces emotional tension and anxiety, thereby promoting better sleep. Moreover, if running time is properly scheduled and sufficient time is allowed afterward for cooling down and calming the body, it usually does not negatively affect sleep.
2. Negative impact
Intense evening running often causes a significant increase in blood circulation speed, raising body temperature due to heat generated during physical activity. This can make falling asleep more difficult, as sleep onset typically requires a drop in body temperature. Generally, one must wait for the body to cool down after exercise before sleep becomes easier. Additionally, vigorous evening running may increase the secretion of adrenaline and other stress hormones, heightening alertness and excitement. These physiological responses can make it harder to fall asleep, thus negatively affecting sleep.
In summary, moderate evening running is generally recommended. Note that if you experience any discomfort after evening running, seek medical attention promptly.
