13 and 14: Keep to a schedule

13. Set a daily wakeup time. Just like it’s best to go to bed at the same time every day, it’s a good idea to keep a consistent wakeup time — even on the weekends. Irregular bedtime and wake-up hours can lead to poor sleep patterns [9].

14. Make up for lost sleep. Stayed up too late the past few nights? Tack on an extra hour tonight to repay sleep debt and get back on track.
