Find out how much sleep you've missed — and how to pay it back
Hours slept each night this week
Sleep debt is the cumulative difference between the sleep you need and the sleep you actually get. If you need 8 hours and sleep 6, you accumulate 2 hours of sleep debt per night — 10 hours after a 5-day work week.
The bad news: sleep debt is real and it compounds. The good news: it can be recovered, but it takes longer than one weekend.
After 17 hours awake, cognitive performance equals 0.05% blood alcohol — legally drunk.
Even one bad night doubles emotional reactivity. Chronic debt causes anxiety and depression.
Sleep debt increases ghrelin (hunger hormone) and decreases leptin (fullness hormone) — you eat ~300 more calories per day.
Getting 6 hours instead of 8 makes you 4x more likely to catch a cold when exposed to a virus.
Sleeping less than 6 hours regularly increases heart disease risk by 48% and stroke risk by 15%.
One week of poor sleep can induce pre-diabetic blood sugar levels in healthy adults.
