Sleep Distribution — United States
You're within the WHO-recommended 7–9 hours. Over a lifetime of 80 years, you'll spend approximately 23.3 years asleep.
🌍 Japan and South Korea average under 6.5h — the world's least. Finland and Norway lead at 7.3h. The global difference between most and least sleep is less than 1 hour, yet the health impact compounds dramatically over decades.
Put It In Context
Elephants sleep 2 hours per day — the least of any mammal. Little brown bats sleep 20 hours. Humans, at 7–8 hours, sit in the middle. But humans are unique in having consolidated sleep (one long block) rather than polyphasic patterns. Dolphins sleep with half their brain at a time, so they never fully lose consciousness. Your 7h is the result of 200,000 years of evolutionary pressure — the jury is still out on why we need it at all.
