Sleep Hygiene: The Complete Guide
Poor sleep is linked to obesity, depression, and heart disease. Master the art of sleep hygiene with these evidence-based strategies for deeper, more restorative rest every night.
Sleep isn't just rest — it's when your body repairs tissues, consolidates memories, and resets your hormones. One bad night hurts; chronic poor sleep shortens your life. Yet 1 in 3 adults sleeps less than 7 hours nightly.
Keep a consistent schedule. Go to bed and wake up at the same time every day — including weekends. Your circadian rhythm thrives on predictability. A 2-hour shift on Saturday night can create "social jet lag" that lingers into Tuesday.
Cool, dark, and quiet. The ideal bedroom is 18–20°C. Body temperature drops during sleep, and a cool room helps that process. Blackout curtains, eye masks, and white noise machines are inexpensive upgrades with outsized impact.
No screens 1 hour before bed. Blue light from phones and TVs suppresses melatonin — the hormone that signals sleepiness. If you must scroll, enable night mode and keep brightness low. Better: read a physical book.
Caffeine cutoff at 2 PM. Caffeine's half-life is 5–6 hours, meaning your 4 PM coffee is still at 50% strength at 10 PM. If you're caffeine-sensitive, switch to herbal tea after lunch.
Bed is for sleep only. Working, watching shows, or scrolling in bed teaches your brain that bed = alertness. Reserve it for sleep and intimacy so your brain learns to wind down when you lie down.
If you can't sleep after 20 minutes, get up. Lying awake stressed only reinforces insomnia. Get out of bed, do something calm (reading, stretching) in dim light, and return when drowsy.
If you follow these basics for 2 weeks and still wake up tired, talk to a doctor. Sleep apnea, thyroid issues, and restless legs syndrome are common — and treatable.
