Summarize:

Your body gets used to doing the same things at the same time. When it comes to sleep, a steady schedule is best. By going to bed and getting up at the same time, your body will become accustomed to sleeping a certain number of hours at night which can help you avoid sleeping too much. Your body will want to wake up. Set a bedtime for yourself, at least eight hours before you must get up. To make sure you are actually going to sleep at your bedtime, set an alarm on your phone about an hour before. That way, you have time to wind down, turn off the electronics, and get ready for bed. One sleep cycle is about 90 minutes; therefore, try to plan the amount of sleep you get around your cycles. In fact, if you find yourself awake slightly before your alarm goes off, you should just get up, rather than entering another cycle. Waking up in the beginning or middle of a cycle can make you groggy. Don't exercise in the three hours before going to sleep. If you exercise too close to bedtime, it may stimulate your mind and body, keeping you awake.
Stay on a routine. Make your bedtime mandatory. Be mindful of sleep cycles. Get exercise in earlier in the day.
