“Caffeine doesn’t allow you to get into deep sleep,” says Michael Breus, a clinical psychologist and author of The Sleep Doctor’s Diet Plan: Lose Weight Through Better Sleep. “It keeps you in the lighter stages of sleep.”
To avoid the “sleep-dampening” effects of caffeine, which has a half-life of 8 to 10 hours, shut down caffeine intake after 2 p.m.
