There's a lot about sleep that we don't understand, like why we even sleep in the first place, for example. Here are nine amazing discoveries biologists have made while trying to solve the mystery of sleep:
- Not sleeping will kill you (and sleep deprivation can lead to all kinds of health problems)
- Sleep solidifies memories
- Your brain is super active while you are sleeping
- Sleep and wake signals in the brain
- Pain is worse when sleep deprived
- Sleep is important for proper healing
- Blue light is bad for sleep
- Sleep cleans your brain
- Early human sleep habits – they probably slept about the same amount of time as we do now, but it wasn’t always restful.
