Sleep is one of the few health habits that touches almost everything else: mood, focus, appetite, workouts and how well you handle a stressful week. Yet it is often the first thing we trade away when life gets busy.
The number to aim for
The American Academy of Sleep Medicine and the Sleep Research Society recommend that adults ages 18 to 60 get at least seven hours of sleep a night. The CDC has reported that about one in three U.S. adults regularly gets less than that.
Seven hours is a floor, not a target to hit exactly. Some people feel best with more. A useful check is how you feel during the day: if you rely on caffeine to function, fight to stay awake in the afternoon or sleep far longer on weekends, you may need more than you are getting.
Why consistency matters as much as hours
Your body runs on an internal clock. Going to bed and waking up at roughly the same times, including on weekends, helps that clock stay steady. The CDC lists a consistent schedule among its first recommendations for better sleep.
Small changes that help
- Pick a wake-up time first. It is easier to anchor the morning than to force yourself to fall asleep earlier. Bedtime tends to follow.
- Give screens an earlier curfew. The CDC suggests keeping TVs, computers and phones out of the bedroom or switched off.
- Make the room work for sleep. Cool, dark and quiet is the goal. Blackout curtains, a fan or earplugs are inexpensive fixes.
- Watch late caffeine. Its effects can last for hours, so an afternoon coffee may still be with you at bedtime.
- Build a wind-down. A short, repeatable routine, such as dimming lights, washing your face and reading a few pages, signals that the day is ending.
When to talk to a doctor
If you snore loudly, wake up gasping, feel exhausted despite enough time in bed, or have trouble sleeping most nights for weeks, mention it to your doctor. These can be signs of sleep conditions that are very treatable.
The takeaway
Aim for at least seven hours, keep your schedule steady and protect the hour before bed. Small, consistent changes tend to beat dramatic overhauls.
