Average humans spend about one third of their life sleeping, but I probably spend about half of my life sleeping. Catching z’s is one my favorite activities to do, I love getting into a cozy bed after a long day, turning on Netflix, and falling asleep to House of Cards. During the day when I feel dog-tired or enervated, I orchestrate a tranquil nap. After a good night sleep or day time nap, I always feel like a rejuvenated newborn baby. That grinded my gears, and prompted me to think, why do we need to sleep? Sleep has been a behavior of humans since the beginning of mankind, it is one of the most basic human needs. We can die of sleep deprivation, before food deprivation. Even though science and technology has evolved, we still don’t know

Through out the night your body will cycle through all the stages multiple times. The first stage is stage 1; it is the lightest stage of sleep. Stage 1 is known as the transitional stage; you only spend about five to 10 minutes in that stage. In stage 1 your body is relaxing, and you are in the midst of wakefulness and sleep, many experience the sensation of starting to fall. In stage 2, it is still considered light sleep, your brain activity and eye movements slow down. Your body temperature also starts to descend. The brain begins to produce fast burst of rhythmic brain wave activity know as sleep spindles. An average person spends majority of their sleep in stage 2. The next is stage 3, it is the transition from light sleep to very deep sleep. Your brain waves are even slower and deep sleeping waves called delta waves occur. At this stage waking up is tough. In stage 4 you will undergo the deepest sleep of the night, only slow delta waves appear. This stage your body will begin to release hormones to repair itself. Stage 4 lasts for about 30 minutes, and for kids it is the stage where bedwetting and night terrors occurs. The last stage, stage 5 is know as rapid eye movements (REM). In the last stage your respiratory rate and brain activity increases, while at the same time your muscles become more relax and turn paralyze. Paralyzing the muscles is a protective measure, so you don’t hurt yourself during this active stage. …show more content…
Even with our new science and technological advancements, we still can not find the answer. Although we still do not have the answer to that question yet, we have found answers to a plethora of other questions. Like how every living organism has an internal clock that regulates their existence called the circadian clock. The clock regulates numerous roles in people’s lives sublimely, from their sleep pattern to cell regeneration. Also, the positive effects sleep has on the body and brain. The brain rids itself of harmful toxins and strengths brain cell connections from the previous day. The body progresses through a number of positive changes during sleep. The body has a chance to recover as the metabolic rate and energy consumption drops, while it has a chance to replenish the energy reserves. Extra protein molecules are created in the body to repair muscles, tissues, cells, and etc. HGH is also released by the purity gland which spurs growth in children and help adults maintain body composition. The cardio vascular system also acquires a rest, with reduction in blood pressure and heart rate. We also discovered all the different stages of sleep and its importance. From stage 1 to REM, all of the stages preform a vital role during our sleep cycles. Countless people overlook the magnitude of sleep and pay dire consequences. Sleep deprivation can cause a multitude of complications from shorter life span to
