When it comes to sleep, 8 is the magic number1. For human adults, 8 hours of sleep a night is considered optimal for overall health, focus, and function. During deep, restful sleep, brain waves slow and enlarge, as if in a car that is idling. During this time, the brain goes through restorative process which allow it to function at full speed the next day. Our bodies have an embedded sleep notification known as sleep pressure. This is a process which occurs on a daily basis in which our neurons slowly tire and eventually, the pressure builds to the point of sleep. Sleep pressure shows itself in yawning, head-nodding, and other sleepy time behaviors. Upon the evaluation of sleep pressure, scientists discovered that sleep, once thought of as an all-or-none type process, is actually not all or none by any means. There has been proof of the occurrence of …show more content…
This phenomenon especially can be seen in microsleep. Microsleep is when sleep interjects itself into daily functioning and causes lapses in consciousness, often due to sleep deprivation. More often than not, people don’t realize that they have had an episode, making it particularly dangerous while driving or performing higher risk tasks.
With all of this in mind, I will discuss sleep in the context of myself, an average college student. According to my Fitbit, this week, I have gotten an average of 5 hours and 39 minutes of sleep per night with two nights of 3.5 hours. When evaluating sleep, scientists will often use the term sleep deficit which defines the deviation from the standard 8
I have outlined to him the pathophysiology of the disorder and treatment options that are available. He will now proceed to a diagnostic sleep study. He has previously had microsleeps when driving a couple of years ago, but has put in place precautions since and has not had any issues of late. It is imperative that he continues to take very strict precautions when driving. He will also need to look at trying to increase his sleep hour
Each year at least 40 million Americans suffer from long term, persistent sleep disorders, and an additional 20 million experience occasional sleeping problems. About 60 million Americans a year have insomnia and it tends to increase with age and affects about 40 percent of women and 30 percent of men. It is estimated that 18 million Americas are suffering from sleep apnea, 12 million have RLS, and 250,000 are affected by narcolepsy. Adults typically need between 6 and 10 hours of sleep per 24 hour period, and most people need approximately 8 hours of sleep per day. Infants generally need about 16 hours per day; whereas, teenagers require 9 hours on average. In the first 3 months of...
As we all know, sleep is an important part of our lives. Without the proper amounts and type of sleep, fatigue and other problems can arise. Generally, we can clearly distinguish between a sleeping person and a person that is awake. With sleeping disorders, the distinction between an awake person and a sleeping person becomes more intriguing. What is the difference, how does it relate to the I-function and consciousness? Each sleeping disorder has its own unique answer to this question. It is essential to understand sleep to fully appreciate it. However, many aspects of it remain a mystery. We do have some degree of understanding of sleep. Within our sleep cycle a type of unusual sleep occurs, REM sleep. During this cycle the periods of REM sleep are interspersed with slow wave sleep in alternation. Each period of REM sleep (there are usually 4 or 5 periods a night) lasts for approximately 5 to 30 minutes. During these periods a sleep paradox occurs. An enormous amount of brain activity takes place; this is sometimes even more activity then when awake. This clearly indicates that sleep is not simply to rest our mind and not to think. So, during this period our brains are extremely active, yet there is usually no input or output. During this period, along with the random eye movement (REM), there is a complete loss of muscle tone. Essentially, at this point, the motor system is paralyzed (normally the body inhibits any movement). The autonomic nervous system also alters its behavior. The regulation of body temperature is lost and the blood pressure, heart rate, respiratory rates shows increased variability. REM sleep can be detected by measuring the electrical activity of the brain with an electroencephalogram. At this point, the EEG will show the same pattern of activity as when the brain is awake.
Narcolepsy is a neurological disorder that affects the control of sleep and wakefulness. This disorder causes a number of symptoms that will be discussed further in depth later on but they are, excessive daytime sleepiness (EDS), cataplexy, hallucinations, and sleep paralysis. Scientists and researchers believe that the cause of narcolepsy is a genetic mutation. This disorder can cause severe disruption to a person's daily life and routine and can be a cause of harm to the person with the disorder as well as those around him/her. There have been case studies and animal research and testing to further understand this disorder its cause and possible cures or medication. Which as of 2014 there is medication to help those with the disorder but there is no cure. To better understand this disorder we have to go more in depth on the topics I have touched on and more in depth on the disorder in general. We will be investigating all the above mentioned topics and more.
Sleep is one of our basic needs to survive and to function in day to day operations, but not everyone needs the same amount of sleep. Some people can survive on very little sleep, i.e. five hours a night, and some people need a lot of sleep, to the extend that they are sleeping up to 10 to sometimes 15 hours a night (Nature, 2005). According to Wilson (2005) the general rule states that most people need from seven to eight hours of sleep. The deprivation of sleep in our society in continually increasing with the demands in society increasing work loads, the myth that a few hours of sleep is only necessary to function properly and that sleep is sometimes considered as killing time (Nature, 2005). Sometimes sleep deprivation is also caused by other situations like sleep disorders, i.e. sleep apnea, chronic insomnia or medical conditions such as stress (Wilson, 2005).
Sleepiness, whether due to sleep apnea, heavy snoring, idiopathic hypersomnolence, narcolepsy or insomnia from any number of sleep-related disorders, threatens millions of Americans' health and economic security (1). Perhaps somewhat most concerning of these disorders are those that allow sleep without having any control over when it happens-idiopathic hypersomnolence and narcolepsy. The two are closely related in that both cause individuals to fall asleep without such control, yet narcolepsy occurs without any dreaming during naps (2). For years, narcoleptic people have been falling asleep in corners, concerned, as they have given numerous attempts to try to stay focused and awake. But besides the excessive fatigue that people experience, there surely must be more that can be associated with causing such sleepiness among people at an uncontrolled level. There might especially not be a reason involving the I-function of the brain, as people are not aware of when necessarily they will fall into their deep sleep.
Sleep is necessary in order for the body to rest, and is a state of decreased consciousness and lowered metabolism. Sleep is very important for all living things. Getting a sufficient amount of sleep has numerous positive effects on humans. In humans, there are five main stages of sleep. As the brain passes through each stage, the frequency of waves slows down. The amount of sleep required for humans varies depending on age. Sleep is vital for the well-being of all living things because it improves both physical and mental health. Humans just can’t get enough of it!
If all of these important activities occur during sleep, why is it that people are so willing to short themselves of this vital activity? Although much about sleep still remains a mystery, research and experiments continue to show how important sleep is to each and every person. Throughout this paper, I will discuss sleep and the effects that it has on performance and health, especially among college students. A college student’s sleeping pattern is a reliable indicator of their level of performance in the classroom and other school-affiliated activities, as a lack of sleep leads to decreased performance. Sleep is directly related to the level of performance and health of an individual; the more rested a person is, the better that person will perform and feel (Dryer, 2006).
Parasomnia refers to a wide variety of disruptive, sleep-related events or, "disorders of arousal." These behaviors and experiences occur usually while sleeping, and most are often infrequent and mild. They may however happen often enough to become so bothersome that medical attention should be sought out. "Parasomnias are disorders characterized by abnormal behavior or physiological events occurring in association with sleep stages, or sleep-wake transitions."(DSM pg. 435)
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. Two articles deal with the issue of sleep deprivation. The College Student Journal published an article about the grade-point average of college students and sleep length, while U.S. News & World Report produced an article dealing with the lack of
Sleep paralysis is a condition that occurs at either the onset or upon awakening of sleep. The medical terms for the two forms of sleep paralysis are hypnogogic and hypnopompic (1). When a person falls asleep, the body secretes hormones that relax certain muscles within the body, causing it to go into paralysis. Doing this prevents the body from acting out a person's dream, which could result in an injury. Sleep paralysis generally runs within one's family or in those who suffer from narcolepsy (2), but there is currently no explanation for why some people get it while others do not.
the sleeper will gradually descend deeper into sleep, becoming more and more detached from the outside world and progressively more difficult to awaken. Stage three is the beginning of deep sleep, occurring about thirty to forty five minutes after you first fall asleep. The deepest sleep occurs in Stage four. Stage three and four has the biggest and slowest brain wave. REM sleep, a mentally active period during which dreaming occurs, provided a biological explanation for this phenomenon. Scientists found that brain activity during REM sleep begins in the pons, a structure in the brainstem, and neighboring midbrain regions. The pons sends signals to the thalamus and to the cerebral cortex, which is responsible for most thought processes. There are several myths about sleep. For one, how much sleep a person should get? According to our text book people should sleep for at least eight hours to maintain sound mental and physical health. But every one doesn’t get the chance to sleep for that amount of time. There is no normal amount of time you should sleep. Everyone is not the same. For one I might sleep for five hours and feel refreshed enough to work another shift. Other hand my cousin might need more then eight hours of sleep to feel refreshed.
Lack of sleep may cause an accident. As you get drowsy, your reaction becomes slow as much as driving drunk.
Important public policy issues have arisen in our modern 24-hour society, where it is crucial to weigh the value of sleep versus wakefulness. Scientific knowledge about sleep is currently insufficient to resolve the political and academic debates raging about how much and when people should sleep. These issues affect almost everybody, from the shift worker to the international traveler, from the physician to the policy maker, from the anthropologist to the student preparing for an exam.
Sleep is very important for human beings. Sleeping means taking rest for every person and each person spends one-third of his lifetime sleeping. Without sleeping, no one can exist in this world. Sleeping is essential for a person’s health and well-being throughout his life. Getting enough quality sleep at the right times helps all people protect their mental health, physical health and safety. A person who does not get enough sleep might suffer from mental disorders, diseases and even harmful situations. Therefore, it is important for every human being to have enough sleep.
