Understanding why we sleep
As you can see, there are several different theories that explain why we sleep. Some of these theories focus on why we sleep at night. Others focus on how sleep interacts with the brain and body. Each theory offers a valuable observation on why we need sleep. One thing that all theories agree on is that getting the right amount of sleep helps people live their best lives.
As a result, it may not matter why we sleep. What is important is that the human body requires sleep to function best. Whether we sleep at night to avoid predators, save energy, restore and repair body and mind, or help process memories, sleep is essential to all living things. Keep an eye out for more updates as the latest sleep science comes out.
