Practicing good sleep hygiene is the best insomnia prevention method. Sleep hygiene simply means maintaining healthy sleep habits on a nightly basis. Don’t stare at screens for about an hour before bed. Keep the TV and laptop out of the bedroom. Make sure your bedroom is cool to aid your body as it lowers its core temperature for sleeping. Always go to bed at the same time every night. Keep your bedroom as dark as possible with blackout curtains. Also get at least 150 minutes of moderate to intense exercise every week to keep your system primed for regular sleep. Always avoid caffeine and other stimulants after lunch, since caffeine stays in your bloodstream for many hours after you drink it. If even solid sleep hygiene practices don’t help you catch some Zs, Cognitive Behavioral Therapy —or retraining your brain for better sleep—might be the next step.
