Consistency matters more than the perfect number of hours
Most adults do well on somewhere between seven and nine hours, but chasing an exact number is less useful than keeping your schedule steady. Going to bed and getting up at roughly the same time — including at weekends — helps your body clock settle, which is usually what makes mornings feel easier.
If you sleep badly, the boring fixes are the ones with the best track record:
- Keep the bedroom dark and on the cool side.
- Stop caffeine by early afternoon; it has a long tail in the body.
- Alcohol makes you fall asleep faster and sleep worse.
- If you are awake and frustrated after about twenty minutes, get up, do something dull in dim light, and go back when you feel sleepy.
