Regular exercise has been consistently shown to improve sleep quality, making it the correct choice. Engaging in physical activity helps to regulate the body's sleep-wake cycle and can reduce the time it takes to fall asleep. Exercise promotes the release of endorphins and other hormones that can enhance mood and relieve stress, factors that are crucial for a good night’s sleep. Additionally, regular exercise can help deepen sleep and increase the amount of restorative slow-wave sleep.

In contrast, increasing caffeine intake is more likely to lead to sleep disturbances, as caffeine is a stimulant that can interfere with the ability to fall asleep and the overall quality of sleep. Watching television before bed can expose the brain to blue light, which may disrupt the body’s natural sleep rhythms, making it harder to fall asleep. Skipping meals can lead to hunger or discomfort at night, which can also negatively impact sleep quality. Therefore, regular exercise stands out as a beneficial lifestyle change that positively affects sleep.
