Getting little sleep is often praised. It is seen as the ultimate dedication and commitment to a person’s work. It might be necessary to pull an all-nighter or loss a few hours of sleep, but this should never become a common practice. Some people even take part in “purposeful sleep deprivation”, which is not sleeping simply because a person does not want too. The human body undergoes major changes during sleep. The changes that occur during sleep are needed to keep the body properly functioning when it is awake.Inside each one of a person’s cells there are “molecular clocks” that aim to keep a person in sync with the sun. This is known as a person’s circadian rhythm or sleep/wake cycle. Adults feel their biggest change in energy between two o’clock in the morning and four o’clock in the morning when they are asleep and around one o’clock in the afternoon and three o’clock in the afternoon. (National Sleep Foundation) The hypothalamus is a portion of the brain that controls the body’s temperature, thirst, hunger, and is involved in the switch between wakefulness and sleep. The hypothalamus is also affected by light, “when it’s dark at night, your eyes send a signal to the hypothalamus that it’s time to feel tired. Your brain, in turn, sends a signal to your body to release melatonin, which makes your body tired. That’s why your circadian rhythm tendsto coincide with the cycle of daytime and nighttime…”. In order to understand the importance of sleep, having an understanding of the different stages of sleep is helpful. Each completed rotation takes about ninety minutes and “on a good night, we cycle four or five times through several stages of sleep…” (Finkel 2018)When people are awake the neurons in a person’s brain form a “jostling crowd, a cellular lighting storm” (Finkel 2018) Using an electroencephalogram, or an EGG a device that records electrical activity the brain, it is shown that the formally wild neurons have calmed and now form neat rippled lines. This indicated that the sensory receptors have been muffled and a person
will soon fall asleep. This is called stage one “the shallow end of sleep” and usually last five minutes. Following the end of stage one there are a series of short, lasting about a half a second,
