Why Do We Sleep?
We sleep to reduce our energy levels, restore whatever we have lost during the day, serve as a survival function, and help us improve our brain development.
Most people think that sleep is such a plain action, but they have never really though about why it is important. They expected short and simple answers to this question.
"Experts say that, despite widespread belief, it is not simply the fact that humans and other animals need rest." (Goode)
It is much more than that; scientists are digging deeper into this topic, trying to answer all of our questions and thoughts.
''You can rest all you like and you still need sleep,'' Dr. Rechtschaffen said.
Experts' thoughts on this topic vary. Even though the question may seem simple, it is not easy or fast to answer. Research on sleeping has been going on since years ago, and we still do not know the exact answer to "We do we sleep?" They have come up with theories that have opened their research into different branches and are now getting closer to a more specific answer. (Goode)
