What lifestyle change could improve overall sleep quality?

Regular exercise is widely recognized as a significant lifestyle change that can enhance overall sleep quality. Engaging in physical activity helps to promote more restful sleep for several reasons.

Firstly, regular exercise can help regulate the body's circadian rhythms, which is the internal clock that controls sleep-wake cycles. By being active during the day, individuals are more likely to feel tired and ready for sleep at night. Exercise also increases the amount of deep sleep one experiences, which is crucial for physical recovery, memory consolidation, and overall well-being.

Moreover, physical activity can also reduce symptoms of anxiety and depression, both of which can interfere with sleep. When these mental health concerns are managed better through exercise, individuals often find that they can fall asleep more easily and enjoy longer periods of restorative sleep.

In contrast, the other options mentioned, such as increased screen time before bed, irregular sleep schedules, and high caffeine consumption in the evening, are known to have negative impacts on sleep quality. These behaviors can disrupt the natural sleep cycle, making it harder to fall asleep and stay asleep, ultimately leading to poor sleep quality. Hence, adopting a routine that includes regular exercise is a beneficial strategy to improve sleep.
