Why Do We Need Sleep?
Typed By: Miracle Taylor

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.
Comprehending these theories can help expand our appreciation of the function of sleep in our lives.
Most of us recognize at some level that sleep makes us feel better. We feel more energetic, happier, more alert, and better able to function after a good night’s sleep. However the fact that sleep makes us feel better and that going without sleep can make us feel worse is just the beginning to understanding why sleep might be necessary. One way to think of sleeping is to compare it to another one of our life-sustaining activities: eating. Hunger is a protective mechanism that has evolved to ensure that our bodies receive the nutrients that our bodies need to repair tissues, function properly, and to grow. 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. And just as eating relieves hunger and ensures that we acquire the nutrients we need; sleeping relieves drowsiness and ensures that we obtain the sleep we need. 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
