This Is What Happens to Your Body When You Get Too Much Sleep

Sleep is a fickle thing. Sometimes it comes unexpectedly, and other times it comes far too late. For me, sleep has always come easily—sometimes too easily. I can't tell you how many times I've fallen asleep after sitting down to "rest" for "a few minutes" after a long workday. Which never seemed like a problem; after all, sleep is important, and many people complain about not catching quality shut-eye.

According to the National Sleep Foundation, though, that might not be so cut-and-dried. The general consensus for how much sleep the average adult should be getting each night is seven to nine hours (according to the findings of a comprehensive sleep study that took two years to conduct). If you're regularly sleeping more than that, something could be wrong with your health, as it turns out.
