Sleep is not a luxury. It is when your brain sorts memories, your body repairs tissue, hormones reset and your immune system recharges. Yet many adults regularly get less sleep than they need, and the effects add up quietly over time.

This guide covers how many hours different age groups generally need, what poor sleep can do to your health, ten practical habits that help, and warning signs that deserve a medical check. It is general information and not a substitute for personal medical advice.

1. How Many Hours of Sleep Do You Need?

Needs vary from person to person, but the CDC and sleep medicine experts publish general ranges by age. See the CDC sleep page for official guidance.

Age groupRecommended sleep per 24 hours
School-age children (6 to 12)9 to 12 hours
Teenagers (13 to 18)8 to 10 hours
Adults (18 to 60)7 or more hours
Adults (61 to 64)7 to 9 hours
Adults (65 and older)7 to 8 hours

3. What Poor Sleep Can Do to Your Health

Area of healthPossible effect of long-term poor sleep
Heart and blood pressureHigher risk of hypertension; see our high blood pressure guide
Blood sugar and weightHarder blood sugar control and weight gain; see type 2 diabetes
Mood and mental healthIrritability, low mood and anxiety
ImmunityMore frequent colds and slower recovery
Focus and safetyTrouble concentrating and higher risk of accidents such as drowsy driving

4. 10 Habits for Better Sleep

Try these habits for a few weeks and notice what helps:

  1. Keep a consistent schedule: go to bed and wake up at about the same time, even on weekends.
  2. Make the bedroom cool, dark and quiet.
  3. Reserve your bed for sleep and intimacy, not work.
  4. Turn off screens 30 to 60 minutes before bed.
  5. Limit caffeine in the afternoon and evening.
  6. Avoid heavy meals and alcohol close to bedtime; alcohol can fragment sleep.
  7. Get daylight exposure in the morning and be physically active during the day.
  8. Keep naps short, around 20 to 30 minutes, and early in the afternoon.
  9. Create a calming routine such as reading, gentle stretching or a warm shower.
  10. If you cannot sleep after about 20 minutes, get up, do something quiet in dim light, then return to bed when sleepy.

5. Warning Signs: When Poor Sleep May Be a Medical Problem

Talk to a clinician if you notice:

  • Loud snoring with pauses in breathing or gasping at night, which may suggest sleep apnea
  • Trouble falling or staying asleep at least 3 nights a week for 3 months or more
  • Extreme daytime sleepiness, even after a full night in bed
  • Morning headaches, or waking with a dry mouth or sore throat
  • An uncontrollable urge to move your legs at night
  • Sleep problems along with depression, anxiety or pain

6. Common Sleep Myths

MythReality
You can fully catch up on weekendsExtra weekend sleep helps a bit but does not erase a weekly sleep debt
Alcohol helps you sleep betterIt may make you drowsy but usually lowers sleep quality
Everyone needs 8 hoursNeeds vary; many adults do well with 7 to 9 hours
Snoring is always harmlessLoud, frequent snoring can be a sign of sleep apnea

7. Make Sleep Part of Your Checkup

Sleep deserves a spot in your regular health review. When you visit for your yearly exam, mention how well you sleep, how rested you feel and any snoring. Our Annual Physical Checkup Guide lists other topics worth raising, and some common blood tests such as thyroid checks may be considered if you are constantly tired.

Conclusion

Better sleep rarely comes from one big change. It builds from small, steady habits. If you have tried good sleep habits and still feel exhausted, it is worth getting checked, since treatable conditions are often behind poor sleep.
