How does regular exercise contribute to better sleep quality?

Regular exercise significantly enhances the sleep cycle, leading to improved sleep quality. Engaging in physical activity helps to regulate the body's circadian rhythms and can promote deeper stages of sleep, particularly slow-wave sleep, and rapid eye movement (REM) sleep, which are critical for physical recovery and mental well-being. Exercise is also known to reduce symptoms of insomnia and anxiety, which can interfere with the ability to fall and stay asleep.

When individuals engage in regular physical activity, it can also lead to increased levels of serotonin, a neurotransmitter that plays a key role in mood regulation and sleep. A consistent exercise routine contributes to overall hormonal balance, including the reduction of cortisol levels, which can improve the body’s ability to relax and transition into sleep. This multifaceted impact of exercise on both physical and mental health underlines its vital role in enhancing sleep quality.
