If your sleep has drifted hours away from where you need it, simply telling yourself to “go to bed earlier” often does not work. You may get into bed at the new time and lie awake because your body is not ready for sleep yet.
A better approach is usually gradual. Move your sleep and wake times in manageable steps, keep your wake time reasonably consistent, use light at the right part of the day, and protect enough total time for sleep while your schedule changes.
