Why Sleep Needs Change with Age
Babies need the most sleep because their brains are developing rapidly. Sleep supports neural connections, growth hormone release, and immune system development.
Teenagers need more sleep than adults due to ongoing brain development, hormonal changes during puberty, and the natural shift in their circadian rhythm that makes them night owls.
Adults need 7-9 hours for optimal cognitive function, physical health, and emotional regulation. Older adults may need slightly less but often have more fragmented sleep patterns.

Can I train myself to need less sleep?
No, you cannot train yourself to need less sleep. While some people have genetic variations that allow them to function on less sleep, most adults genuinely need 7-9 hours. Chronic sleep restriction leads to cognitive impairment even if you feel adapted to it.
Is it true that older adults need less sleep?
Older adults (65+) need about 7-8 hours, only slightly less than younger adults. However, they often have difficulty getting uninterrupted sleep due to changes in sleep architecture, medications, and health conditions.
