How Many Hours of Sleep Do You Really Need?
Spoiler: It's not 8 hours for everyone. Your age, genes and lifestyle dictate your ideal sleep time.
By Age Group
- Newborns (0-3 months): 14-17 hours
- Adults (18-64): 7-9 hours
- Seniors (65+): 7-8 hours
Warning: Consistently sleeping 6 hours increases diabetes risk by 30%.
Quality vs Quantity
Uninterrupted sleep (even if shorter) often beats longer but fragmented sleep.
