If you're searching for a better night's sleep, let your feet lead the way.

Regular exercise can help to protect your sleep quality. In a study, low levels of physical activity were linked to a higher risk of chronic insomnia later in life. For best sleep results, try to work out in the afternoon when you can and avoid vigorous exercise within three hours of bedtime.

Regular exercise may help you sleep not only more soundly, but also longer. Researchers suspect that sleep patterns are easily influenced by activity levels. Even moderate-intensity exercises can help promote sleep, although vigorous exercise appears to bring the most dramatic benefits.
