Losing sleep produces significant consequences to the overall health of a body. There have been numerous tragedies in history linked to errors by tired, sleep-deprived humans. Two major events caused by fatigue were the Exxon Valdez Oil Spill and the NASA Challenger shuttle explosion. The horrendous outcomes of these events are why humans need a better understanding of how sleep affects their quality of life. (NSF) When sleep is lost, there may be detrimental effects to your health and the well-being of others.
Sleep is “the resting state in which the body is not active and the mind is unconscious”. (English) A person who sleeps well will awake more refreshed and alert. A good night’s sleep has a major impact on how a person looks, feels, and their ability to function normally on a daily basis. (What) Everyone must sleep because sleep is essential in sustaining normal levels of cognitive speech, memory, and critical thinking. The brain’s development is directly affected by the amount of sleep the body receives. (BBC)
The sleep-cycle is what makes everyone sleep and wake up every night and morning. The basic mechanisms of the sleep-wake cycle consist of approximately 8 hours of nocturnal sleep and 16 hours of being awake. This cycle is controlled by combination internal influences of both sleep homeostasis and circadian rhythms. Homeostasis is “the process by which the body maintains a steady state of internal conditions such as blood pressure, body temperature, and acid-base balance”, and Circadian rhythms “refer to the cyclical changes-like fluctuations in body temperature, hormone levels, and sleep that occurs over a 24 hour-period”.

Sleep deprivation in hospitalized patients can result in increased morbidity and mortality, and can lower their quality of life. Hospitalized patients require more than the average amount of sleep to aid in recovery, but often get an inadequate amount of sleep or experience poor quality sleep. There are increased frequencies of awakening or being awakened too early in the morning, difficulty falling asleep, an increased need for sleep medications, poor sleep quality, an increase in frequency of napping and nightmares. Sleep-wake cycles contribute to adequate protein synthesis and cellular division that is crucial to sustaining the healing process and maintaining immunity.

They used an electrooculogram, which they taped to the patient’s eyelids and it recorded eye movement which became rapid during REM sleep. They also used an electromyography to measure movements of the chin and neck during sleep. Surprisingly, they found that there was little movement in the chin and neck region, which is still...
