How does regular exercise impact sleep quality?

Regular exercise has a positive impact on sleep quality for several reasons. Engaging in physical activity helps to regulate the body's circadian rhythm, which is essentially the internal clock that dictates sleep and wake cycles. When people exercise, they often experience an increase in body temperature, followed by a drop when they cool down post-exercise. This drop in temperature is conducive to sleep as it mimics the body's natural cooling process during sleep onset.

Additionally, exercise can elevate mood and reduce anxiety and stress by releasing endorphins, which further facilitates the ability to relax and fall asleep more quickly. Studies have shown that individuals who regularly engage in moderate exercise report better sleep quality, including increased deep sleep phases and overall time spent sleeping. This combination of benefits illustrates why regular exercise not only improves the ability to fall asleep but also enhances the quality of that sleep, leading to more restorative experiences during the night.
