When I ask my clients why sleep is important, I tend to hear things like ‘it recharges your batteries.’ This is actually a common misconception. Sleep not only recharges your batteries, it installs new updates!
When you sleep, not only do you regain energy, but your brain also resets itself for a new day. This includes its hunger mechanism- people who do not get enough sleep tend to overeat by 300 calories the next day! Adequate sleep also improves your ability to manage stress.
So how much is enough? 8-10 hours is recommended for adults. More than 10 hours is actually shown to make you feel more tired the next day. If you miss your nightly 8-10 for a special event, its best to just try and get back on schedule the next night. There’s no such thing as sleeping extra to make up for lost sleep.
