Watch Your Caffeine and Alcohol Intake
Give yourself a coffee cutoff (we know, we know) so that your body can process it out by the time you're ready to hit the hay. Noon works for many people as the hard stop time.
Also be mindful of alcohol. "Alcohol can disrupt your circadian rhythm and directly interfere with your sleep cycle," Dr. Heneghan said. "While alcohol may help you fall asleep faster, it contributes to poor overall sleep." One reason you don't feel as rested? You may not get as much REM sleep, the deep, restful slumber that helps your brain process the information it's collected. "Not getting enough REM sleep can negatively impact your short-term memory, cell regeneration, and mood, so you may feel groggy when you wake up after a night of drinking," he explained. Skip the nightcap, and opt for a hot tea instead.
