The next time you tell yourself that you’ll sleep when you’re dead, realize that you’re making a decision that can make that day come much sooner. Pushing late into the night is a health and productivity killer.
According to the Division of Sleep Medicine at the Harvard Medical School, the short-term productivity gains from skipping sleep to work are quickly washed away by the detrimental effects of sleep deprivation on your mood, ability to focus, and access to higher-level brain functions for days to come. The negative effects of sleep deprivation are so great that people who are drunk outperform those lacking sleep.
Why You Need Adequate Sleep to Perform
We’ve always known that sleep is good for your brain, but new research from the University of Rochester provides the first direct evidence for why your brain cells need you to sleep (and sleep the right way—more on that later). The study found that when you sleep your brain removes toxic proteins from its neurons that are by-products of neural activity when you’re awake. Unfortunately, your brain can remove them adequately only while you’re asleep. So when you don’t get enough sleep, the toxic proteins remain in your brain cells, wreaking havoc by impairing your ability to think—something no amount of caffeine can fix.
Skipping sleep impairs your brain function across the board. It slows your ability to process information and problem solve, kills your creativity, and catapults your stress levels and emotional reactivity. Read article
