I mean what kind of super advantage do we have by spending the night when its already hard to see shit, god forbid potential Predators, unconscious?
In: Biology
Sleep is essential for good health. In fact, we need sleep to survive — just like we need food and water. So, it’s no wonder we spend about one-third of our lives sleeping.
Many biological processes happen during sleep:
The brain stores new information and gets rid of toxic waste.
Nerve cells communicate and reorganize, which supports healthy brain function.
The body repairs cells, restores energy, and releases molecules like hormones and proteins.
A lot is still unknown about the purpose of sleep. However, it’s widely accepted that there isn’t just one explanation for why we need to sleep. It’s likely necessary for many biological reasons.
