However, with several high school students, only a few hours of sleep is gotten every night and this sleep deprivation is physically and mentally detrimental to the student. Sleep has an important role in human health. Obtaining the recommended quantity and quality sleep at the proper times helps in protecting human safety, mental and physical health. During sleep, the body heals and revitalises damaged cells, the cardiovascular system is rejuvenated and toxins accumulated during waking hours are disposed of. Sleep also encourages learning and memory and plays a crucial role in appetite and regulating mood.
A long lifespan expectancy have modern people believe that health and the way people live today is much healthier than in the past. Humans have not changed much biologically from early man, but the way of life has changed drastically. I have chosen to read Go Wild by John J. Ratey, MD and Richard Manning, because I am interested in learning how a person can reach a higher level of health naturally and biologically. Go Wild This book provides an elaborate and detailed explanation of how ancient people used to live and how with the emergence of agriculture and farming, modern people’s diets and lifestyles have changed. Beside the information provided, the authors, Ratey and Manning, also connect with readers and those that are trying to improve
Their body balance is disturbed and not getting sufficient sleep affects the working of their normal body functions. Metabolism can be affected and they can also experience sudden loss/increase of appetite. An evident dose-dependent relationship between duration of sleep and obesity has been noted, which shows that not getting enough sleep can lead to obesity. Night shift nurses can thus experience a plethora of health issues. According to the previous research finding, night shift nurses can experience change in their Glucose tolerance due to sleep restriction and can even lead to diabetes in female night shift nurses.
All of us have had nights that we have struggled to sleep, or were prevented from sleeping due to our busy lives. Correspondingly, our brains on the mornings after these nights of little sleep may feel the effect in a major way. There are fluids in the brain, that are only produced during a time of slumber, which remove wastes from the cells and allow us to think clearly and focus more. If the brain did not produce cerebrospinal fluid wastes would build up and clog the spaces between blood vessels and tissues. The long lasting effects of poor sleeping habits are thoroughly explained in a TED Talk by Jeff Illiff, where he states that, “worsening sleep quality and sleep duration are associated with a greater amount of amyloid-beta building up in the brain” (Illiff).
Sleep is one of the most important biological aspects of life. Many organisms, including humans, require sleep in order to maintain health, and feel more alert during the day. There are severe consequences if not enough sleep is obtained, such as increased risk of heart disease, depression, and rapid skin aging. In our modern society, many people, including teens, do not receive much sleep. As a result, there is much debate going around regarding whether or not the high school start time should stay the same at around 7:30, or start later in the morning.
3. Theoretical Framework 3.1 Importance of Sleep Sleep is something that almost all living things do all the time, and humans spend about one third of their lives sleeping. But the question is, do we know why we all do it? Well first off all, sleep is one of the strongest biological needs that organisms have. “A 10- year- old sleeps, on average, nine or 10 hours a night, but sleep time can vary a lot between four and 12 hours.” (Farndon, James, Johnson, Royston, Steele & Walters.
There’s plenty the medical field still doesn’t understand about sleep. In fact, no one is quite sure why human beings need to sleep. But sleep is absolutely vital. Sleep plays a major role in human health. A poor night’s sleep has significant negative effects.
Sleep is a crucial part of everyone’s daily lives. It allows the body to rejuvenate and regulate all important bodily functions. Each night, all humans must hit a certain number of hours of sleep to get the maximum benefits produced during those hours. With all the late-night cramming and studying for hours, it is fair to say that college students are not getting their recommended amount of sleep. Is it fair to say that college students are sleep deprived?
