Have you ever gone to bed and wondered what does sleep do to your physical and mental health? Sleeping has effects on our physical heart as well as our mental health (disorders, etc.) Some doctors say that lack of sleep makes our heart deteriorate. In the article. “Sleep Problems May Increase The Risk Of Heart Attack And Stroke." A Harvard professor stated "Sleeping less than four or five hours a night for three or four nights has measurable effects on insulin and cortisol effects”(Dry Redline of Harvard) Doctors at Harvard had done research and They have done observational studies that connect poor sleep with poor cardiovascular outcomes. In the article it states that Sleep apnea makes the back of the throat relaxes which leads to cutting off oxygen. . They are different ways that sleep problems affect the heart in many ways. People with sleep problems, blood pressure do not drop and may even rise. High blood pressure damages the lineage of blood vessels. Researchers have found a way to connect sleep with education. Gary Scarpello who wrote "Lack Of Sleep Could Be Trouble For CTE Students” , did a research study with liberty mutual showed that teens had an average of 7.2 hours of sleep on school nights and 33 to 75 % of all students have sleep problems. In the article it had stated that not getting enough sleep can cause impaired hand eyed coordination, reaction time and brief mental lapses. (Scarpello). The same researchers also found out that Sleep helps restores brain functions such as alertness, metabolism, and memory and regulate hormones (Scarpello). Researchers Mary A. Carskardon and A.R. Wolfson studied 3,120 Rhode Island children. They had figured out that college students who slept more than nine hours a night had a gr... ... middle of paper ... ...pr; 20 (4): 267–277.

(Durmer & Dinges 2005). The average college student is sleeping 6.7 hours during the weekdays and 7.4 hours on weekends. The standard person needs 7.5 and 8 hours per night, which means that students, specifically college and high school, are not receiving the necessary amount of sleep to function properly. Single adults with full-time jobs had greater difficulty falling asleep than those with significant others and without jobs. “An estimated 40 percent of American adults admit that their work suffers when they are sleepy.” In general, no matter the assignment, the cognitive performance becomes progressively worse as the assignment extends. This can be classified as the effect of fatigue when the brain can no longer process any information and has chosen to shut down from loss of sleep. Specifically, college students are reported as to be suffering more than other entities from working odd hours, long studying sessions, excessive eating & drinking habits as well as taking periodic naps whenever they can during the day. In order to earn the necessary grades to stay in college, students have to risk their health in order to finish the assignments
While insomnia is essentially unrelated to the risk, it is found that short sleep has to be accompanied by sleep disturbance in order for cardiovascular events to occur. Evidence suggesting a modest positive association between short sleep duration and CVD, especially myocardial infarction, was observed in individuals with frequent insomnia symptoms (hazard ratio of 1.42; 95% CI 1.15-1.76). However, the validity of the sleep habits is questioned as they were measured at baseline only and could have changed over the years. The authors also referred to a similar study by Chandola et al. that reported that individuals with disturbed sleeps have an increased risk of death from CVD [3].
The vulnerability of the body to diseases increases as sleep deprivation continues. The immune system is greatly affected and defenses are weakened, leaving the body exposed to the changing environment. Not all changes happen externally, internal changes are fluctuating as well. For instance, sleep fragmentation with feelings of choking and daytime sleepiness are mechanisms for anxiety shown in sleep apnea (Fong329). Continuous interruption of sleep can make a person believe that they won’t get any better. This lays out a blueprint for unwanted thoughts and actions. When a sleep disorder is present, the individual should expect further complications and visits to the doctor. Seeing a person who is sleep deprived can further conclude the danger of it. An individual who simply hasn’t sleep in days will not be aware of the environment as much, which will lead to stumbling, running into things, and other tangible dangers. This also makes work related tasks much more difficult. Depending on the importance and alert level needed, having enough sleep is imperative. Indeed, weight gain is noticeable in people who have sleep disorders. Increased BMI relates to severe sleep obstruction, making a solid link between obesity and sleep deprivation (Bocicor 223). A hormone called leptin tells the body to stop eating, being sleep deprived will make less leptin. This causes the body to want to eat,
Lack of sleep can affect health and should be prevented before it is too late and before the disorders can increase. More research would need to done to actually find different treatments instead of surgeries and medicines. However, the research that has been conducted and reviewed shows that sleep deprivation should not be taken lightly, it is something that can even lead to death according to many research conducted which was discussed in this literature review. People who have don’t have enough sleep can end up hurting themselves or have different disorders and diseases.
Sleep is crucial to lead a very happy and healthy life. Without sleep, people can become less focused and are constantly tired during waking life. “Sufficient sleep is increasingly being recognized as an essential aspect of chronic disease prevention and health promotion” (Are You Getting Enough Sleep?). To fight threatening diseases and to maintain a healthy lifestyle, a good night’s sleep is number one on the to-do list. However, most people think they have more important things to do other than lie down and rest, but sleep is essential to a healthy life. Putting down a distraction and going to bed is quite difficult to do, but people need a good quality and quantity amount of sleep each night. “Sleep affects mentality, creativity, physical vitality, and healthy weight. It is also not just the quantity of sleep you get, but the quality of sleep you really have to pay attention to. ” A large amount of people try to sleep as little as possible. There are too many factors at play that people would rather be doing, but sleep is just as important for happiness and good health as exercise and nutrition are (How Much Sleep Do You Need?). Lack of sleep causes mental and physica...
The researchers at Brigham and Harvard Medical School in Boston found lack of sleep may lead to breast cancer. Melatonin, and hormones are produced by our body to promote continue to sleep. However, when the levels of melatonin reduce, our body releases more estrogen, which leads to risk of breast cancer. In addition, the researcher also found that lack of sleep in a long-term seems to be associated with increased heart rate; it means blood pressure increases and the levels of certain chemicals are higher which might linked with inflammation, which can put extra strain on our heart. United States is the country with high percent of the people from lack of sleep, 8 out of 10 people are lack of sleep due to stress, drinking alcohol or caffeine in the afternoon, exercising close to bedtime, and working or doing other intense activities before getting into bed can cause awakens
The extent and eminence of sleep has a profound impact on learning and memory. A sleep deprived person cannot focus attention optimally and cannot learn efficiently. “Sleep is a biological phenomenon that is modulated by the plasma concentration of melatonin and with influence on behavioral aspects and memory” ( Donadon 2016). All through life sleep plays a biological part in memory. Sleep has a role in the alliance of memory which is essential for learning new information. As some may know, many college students do not get adequate sleep but what effect does this have on their way of learning?
In the American Society, sleep deprivation is one of the most common problems. It is a problem that causes, in many different ways, harm to our bodies and personalities. It has shown a decrease performance with students in high schools (falling asleep in class and failing in almost every subject area). Studies proved that students who were sleeping longer obtained better grades across the board. In colleges and universities, these students normally spend late night cramming

Many times people think they can accomplish more if they could eliminate so much sleeping time. However, they are only hurting their productivity if they lose sleep.

A survey revealed that most people sleep less hours than the recommended hour given and have sleep difficulties and sleep pattern problems. According to Damien Leger, Virginie Bayon, and Alice de Sanctis, the author of The Role of Sleep in the Regulation of Body Weight, “Having a regular good night sleep is recommended as one of the major requirements for good health in children, but also in adults” (1). Having a good night sleep is essential for the body to function properly and for the brain to develop well. After students’ sleep, they are likely to perform better when it comes to memory task. Also, the amount of sleep that a student get determines how he or she performs the next day. Because sleep is essential for the body, it means that sleep also participates in health regulation. There are several reasons and causes of daytime sleepiness which has a major impact on the actions and lives of people among ages.
