Sleep. When we were little, we didn’t want to go to bed in fear of missing something (#FOMO before Fear Of Missing Out was a thing, if you think about it). We also maybe didn’t enjoy naps. Now, as adults, when sleep is elusive, we kind of think good naps and going to bed and waking up refreshed are a treat.
You want to maintain a healthy weight?
You want to remember stuff?
You want to perform well in school, at work, or in sports?
Sleep. Sleep. Sleep. Yes, yes, yes. Sleep appears to be a factor in helping us do all of these things.
Have you ever heard of defragging your computer? Things get streamlined and compiled. Sleep kind of does that for our brains. Obviously you need to do other things to make all this happen. What we eat, our activity level, training, and so on.
Bottom line? Taking care of yourself includes rest/sleep. Good things can happen while you are sleeping.
