Regulating sleep is something our bodies do that is as natural as eating, drinking, and breathing. This implies that sleeping serves a similar role in our health and well being.
Even though it is difficult to answer the question “Why do we need sleep?” scientists have developed several theories that may explain why we spend a third of our lives sleeping.

Although it is easy to grasp the role that eating serves sleeping and eating are not as different as they may seem. Sleeping and eating are regulated by powerful internal drives. Going without food produces the uncomfortable feeling of hunger, while going without sleep makes us feel extremely sleepy.

Still, the inquiry remains: Why do we need sleep at all? Is there a single main function of sleep, or does sleep serve many functions? All human beings need sleep- old, young, healthy, sick-need sleep. Thus, everyone should have an interest in this natural phenomenon. However, most people never question what sleep is and why they must get it. This paper will explore
