8. An inconsistent sleep routine
Going to bed and waking up at different times every day can play havoc with your shut-eye. “A routine with a regular bedtime and wake time is the number one thing that makes sleep better,” says Dr. Samuels. Try to hit the sheets within one or two hours of the same time every night and aim for the same window when getting up.
When you have the urge to sleep in on weekends, Dr. Samuels suggests putting a limit on how long you let yourself sleep. “Catching up on sleep is important, but there’s a window. It’s reasonable to sleep in for an hour or two, but sleeping past 10 or 11 a.m. starts to screw up your sleep for the next week,” he says.
