How Much Sleep Do You Need?
Sleep needs change with age: most adults need 7 to 9 hours, teenagers 8 to 10 and school-age children 9 to 12. These are population guidelines, not individual prescriptions; daytime function and long-term patterns matter more.
By age
Adults 7 to 9 hours; 65+ 7 to 8.
Teenagers 8 to 10; school-age children 9 to 12.
When to seek care
Persistent insomnia, heavy snoring/apnea or uncontrollable daytime sleepiness.
Do not rely on long-term sleep aids or supplements instead of an evaluation.
