What Happens to Your Health If You Sleep 6 Hours Instead of 8?
The Answer
+385 calories/day craved
The Full Picture
Sleeping 6 hours instead of 8 triggers a 24% increase in ghrelin (hunger hormone) and a 16% decrease in leptin (fullness hormone). This drives an extra 385 calories per day in food cravings. Over a year, that's a potential 14-lb weight gain from sleep deprivation alone — not counting impaired recovery, cognition, and immune function.
