Chapter 4 Writing Assignment Amy Edwards Department of Psychology, Eastern Gateway Community College PSY101: Intro to Psychology Dr. Kristen Jeffries November 5, 2023

2 Chapter 4 Writing Assignment When thinking about sleep most people don’t realize how not getting enough of it can cause issues. These issues are negative effects that are called sleep deprivation. The five most concerning causes of sleep deprivation are daytime sleepiness, impaired mental function, mood changes, reduced immune system, and weight gain. We all know that if we don’t get enough sleep at night that is it going to cause us to be sleepy during the day and leave us less likely to enjoy our day. With that come impaired mental function where if you're sleepy then you can’t be as alert and could have difficulty making daily decisions. When you can’t make decisions on top of being tired it can cause mood swings, or being more irritable and frustrated. When you have all these items combined it starts to affect the body by weakening the immune system making it easier to get sick, or causing your appetite and metabolism to be affected making you gain weight over an extended period of time. Over time, that a lack of sleep will lead to an increased development of a toxic protein in the brain that is called beta amyloid and that is associated with Alzheimer's disease because it is during deep sleep at night when a sewage system within the brain actually kicks to high gear and it starts to wash away this toxic protein (Tech Insider, 2017) In addition, sleep deprivation often results in depression-like symptoms. These effects can occur as a function of accumulated sleep debt or in response to more acute periods of sleep deprivation (Spielman et al., 2020). While disruptions in circadian rhythms can have negative consequences, there are things we can do to help us realign our biological clocks with the external environment (Spielman et al., 2020). The amount of sleep we get varies across the lifespan. When we are very young, we spend up to 16 hours a day sleeping. As we grow older, we sleep less (Spielman et al., 2020).
