Pe 10 Sleep Journal

There are four main reasons why we sleep. The first is for cardiovascular relaxation which lower blood pressure, lowers heart rate, and lowers metabolic rate. The second reason is for mental and physical restorative properties. Lack of sleep will then manifest itself with physical and cognitive side effects such as fatigue, difficulty focusing, slower response times, memory problems, decreased balance, and decreased ability to perform tasks. The third reason we sleep is to help with learning. Studies have shown that good sleep prior to taking tests increases performance. Finally sleep is the only cure for sleepiness. Daytime sleepiness can cause a person to fall asleep while reading, watching television, talking to others, or even driving. Not getting enough sleep puts people at risk for hypertension and coronary events. It also increases morbidity and mortality.

On the importance of sleep, Dalai Lama quotes "Sleep is the best meditation." A sound sleep is a key to overall health. Lack of sleep affects mood, increases the risk of psychiatric disorders and depression, cardiovascular diseases and also lowers immune system health. Sleep is utmost important for our body to rejuvenate after the day's exhaustion. And as researchers acquire more knowledge about its purpose -and the adverse side effects of not getting enough- the significance of getting a goodnight's sleep becomes even more comprehensible.

For children, a lack of sleep leads to behavior problems. They become more hyperactive, irritable and have trouble staying focused and learning at school. Sleep loss also weakens their immune system, making them sick more often with more missed days of school.

Some of the main causes are stress of daily life, anxiety, fear, old age, medical or mental health conditions, and trading sleep for work or play. Often times, people mistake sleep disorders for stress and ignore them. This can lead to more serious problems and in the rare case, death. One third of Americans have symptoms of insomnia, and less than ten percent are identified by primary-care doctors (webmd.com). Losing sleep for a long time can result in chronic insomnia which can be difficult to treat and lead to several side effects. Some common and immediate symptoms can be fatigue, lack of energy, headaches, irritability, and muscle fatigue which causes the muscles to ache when not rested. Other side effects are a lack of concentration, nausea, memory lapses, and loss of attention and alertness. A person's performance and alertness can go down 32 percent with just one night of not enough sleep (webmd.com). Job and vehicle accidents and injuries can be caused by the lack of sleep because a person isn’t capable of staying awake. Memory loss can also be a problem; impairing it and the cognitive ability which helps think and process information. In the long run, lack of sleep can have some minor effects and also some major ones. It can increase blood pressure, cause depression and mood problems, or lead to a heart attack, heart failure or a

Sleep is a critical component to memory, metabolism, immune function, learning, etc. After a good nights sleep, humans take in information better Also, after learning new information, a good sleep can help humans process and cement the knowledge in their brains. Getting a good sleep can also help protect physical health, mental health, and your life quality. In teens sleep also supports growth and development. Sleep does not just improve that persons life, but it also improves the person's ability to work, learn, react, get along with others, and think, which would also allow people to be safer in how they act, which would be beneficial for everyone around them. Sleep also improves physical health. For example, a study done on teenagers showed that for every hour of lost sleep, that persons odds of becoming obese would rise. Not only does loss of sleep increase the odds of obesity, it also increases the risk of kidney disease, heart disease, stroke, diabetes, and high blood pressure. Also, sleep deficiency can greatly affect student drivers. Statistics show that around 100,000 car accidents occur every year because of sleepy drivers, resulting in around 1,500 deaths. Studies have also shown that being sleepy while driving affects your ability to drive more than

For instance, people who suffer from apnea, a common breathing malfunction that causes them to lose sleep, often suffer from depression. But Stickgold says that one study, in which the apnea was successfully medicated, and the depression was not, revealed that the depression corrected itself -showing that ensuring a good night’s sleep cured the depression. Everyone needs eight and a half hours of sleep out of every twenty-four (Ratey & Manning, 2015, pg. 131). Therefore, sleeping is very important in our daily lives, loss of sleep can lead to many diseases in our lives. Upon completion of this book and the week 2 assignment, I was able to realize the important of sleep and I think for not having enough sleep has a major contribution to my weight gain and being obese. In corroboration, the long-term effects of sleep deprivation are real. It drains your mental abilities and puts your physical health at real risk. Science has linked poor slumber with all kinds of health problems, from weight gain to a weakened immune system. Along with eating too much and not exercising, sleep deprivation is another risk factor for becoming overweight and obesity. Sleep affects the levels of two hormones, leptin and ghrelin, which control feelings of hunger and fullness. (Ann, 2017). I realized that when I started working night shift, that was when I started gaining weight drastically because I was unable to have enough sleep. When I first stated

This scientific article, from the International Journal of Pharma and Bio Sciences (IJPB), investigates the modern issue and association between sleep deprivation as a risk factor for obesity. The journal begins to explore the idea that inadeqaute sleep or partial sleep deprivaion may contribute to the development of obesity as a result of metabolic changes in the body. To add, the

Sleep is an essential part of life. Without sleep, the body does not get the energy that it needs to function. Yet a large amount of people do not get anywhere near the amount of sleep they need. Whether it is because of medical reasons or because there just is not enough time in the day, sleep deprivation is a major problem in today's society. The many people who do not get enough sleep usually end up suffering the consequences. No good can come from not getting enough sleep. Sleep deprivation has many negative effects, most serious of which are a decline in proficiency in school or work, emotional irrationalness, medical maladies, and serious weight changes.

Sleep can also be looked at to help the fight against obesity. Studies have shown that on short nights of sleep people consume more calories and most of the increase is calories from fat (St-Onge 2011). This study looked at people with a BMI of 22-26 on a short night’s sleep (4 hours), and a normal night’s sleep (9 hours). The level of activity in people on short versus long nights of sleep was not significantly different, however their increased caloric intake was ~300 on short nights of sleep, most of which were snacks (St-Onge 2011).

Sleep is important as it helps you keep your body healthy and full of energy. Your body seems to almost shrink when not given the proper sleep. You don't retain the nutrients that you need to keep in order to keep your weight and energy up. With this you can do more than you use to, won't be able to lift as much and will not be able to do straining activities like you use to. This can often lead to stress and on occasion fights with family members as it seems like you aren't doing your best to them. This can lead you into multiple of things as well as jumble up your emotions. I find that when I go more than two days without enough sleep I get moody, often angry and snap on anyone near me. Often times I get sad and an instant later I am happy. It also strains relationships with anyone. You get friends that constantly want to go out and have fun, friends that want to go watch a movie or friends that grow irritated when you stop talking to them. It messes with you emotionally and messes with how you think and react to certain things. In my personal experience I often find myself depressed at times or slow to react to things that I am normally able to react fast to.

Why is sleep so important to us? There have been studies done that suggest that sleep deprivation can be detrimental to or decrease the function of our immune systems. Just think, how often was it that after many days of continual sleep deprivation did you start to think that you had a cold? Sleep deprivation can also result in a decrease in core body temperature, decrease in the release of growth hormone, and possible cause an increase in heart rate variability. Sleep also seems to be important in order for our nervous system to work properly. Without sufficient amount of sleep, our behavior and our ability to do things are impaired. We feel drowsy and are unable to concentrate after not getting enough sleep. With enough sleep deprivation, it has been found that some begin to hallucinate and develop mood swings. Higher-ordered cognitive task become more difficult to do where it has been shown that tests that require speed and accuracy have lower results compared to those that are not sleep deprived. Judgment is also impaired; it has been tested that riskier behavior is more likely to occur when sleep deprived. (2).This is part of the reason why you should not drive when you are sleep deprived. Aside from the risk of falling asleep at the wheel, since judgment is

(Backgrounder) A lack of sleep has been linked to risky health behaviors, such as lack of physical activity, suicidal thoughts or actions, and substance use/abuse. Sleep deprivation can lead to obesity and type 2 diabetes. (Minges)

An absence of sleep slows people down mentally. Sleep plays a major role in thinking, concentrating, and retaining new information that is learned throughout any given day. People who are constantly sleepy are less alert in class or at work, and they will get less work done than someone who had a good night of rest. While sleepy at work or at school, one might be more concerned on sneaking a nap than getting work done. Sleep is also needed to help with reasoning and problem solving. Someone who is tired will have a harder time taking care of the same responsibilities they do when they are fully rested. So even if one does go to work, and tries to concentrate and power through their work, their work value will be of lower quality than normal. Going to work without enough sleep is simply a waste of time. Work produced while tired will probably need to be redone, refined, or even thrown away. The storing of memories is another function of sleep. If not enough sleep is obtained, then the mind will be less likely and less able to remember what is experienced or learned during the day. So, even if one was having fun partying at a club instead of working, the memories of those events might not be stored due to a lack of sleep. It is better to miss work to get home and sleep than to power through every day tired working long hours, and have the

Sleep deprivation can have lasting effects on the human body. Including the central nervous system, immune system, respiratory system, digestive system and cardiovascular system. Just like air and water, the body must sleep to function. It is during sleep that the body heals and restores these systems. Eventually, if the body is deprived of the time to heal, it will be vulnerable to all kinds of illnesses and long-term diseases. In addition, the person’s mental well being is called into question as they stop making rational decisions. In fact, those that sleep less than the recommended hours each night, are increasing their chance of an early death. The following signs are the most obvious of that of a sleep deprived person: excessive sleepiness, constant yawning, irritability, anxiety, lack of concentration and daytime fatigue.

Sleep is as important to the body as eating healthy and staying hydrated. Sleep has a lot of positive results on the body like for example it helps with muscle growth, tissue repair, protein synthesis, and growth hormone release, all which can only occur during sleep. Other rejuvenating aspects of sleep are specific to the brain and cognitive functions. Studies have shown that after people sleep they tend to retain information better which helps with memory tasks. Without sleep or the lack of a significant amount of sleep the body cannot function to its fullest potential. The body then struggles with the task of performing everyday activities. So it is important to sleep.
