7. Have a Cut-Off Time for Caffeine Use
Caffeine is excellent at getting you up in the morning, but it’s not great for your overall sleep cycle, especially if you’re drinking coffee throughout the day. It takes about six to eight hours for caffeine to leave your system completely, so if you’re drinking coffee after 2 in the afternoon, you will have difficulty falling asleep. Drinking caffeine has also been shown to reduce the slow-wave sleep period, which means you’re not getting as much deep sleep as your body needs. It would be good to limit the amount of caffeine you have in a given day, especially cutting caffeine off around noon.
