Postpone Your Rhythm
If you have an early sleep-wake rhythm and feel it is restricting your life, you can try shifting it later. Go to bed 15–30 minutes later than usual. Repeat this each night until you hit the desired bedtime rhythm. Stick to your new rhythm and eventually, your body adjusts to the new rhythm and you'll start waking up later. Be careful to keep the rhythm consistent, even on weekends!
If your wake-up time doesn't shift even after a week, stop the experiment and get back to your previous rhythm. (If you still feel having an early rhythm is a problem for you, we recommend discussing the issue with your general practitioner or doctor.)
