Regular exercise positively influences sleep quality by promoting deeper, more restorative sleep cycles. Physical activity helps regulate circadian rhythms and decrease symptoms of insomnia and sleep disturbances. Exercise facilitates the release of endorphins, reduces anxiety, and can alleviate stress, all of which contribute to better sleep outcomes. Engaging in aerobic and strength-training activities has been shown to improve not only the duration of sleep but also its quality, enabling individuals to wake up feeling more refreshed and alert.
