What happens if stay awake too long




















Kennedy Airport, my body was giving out, too. While imposing a monologue on my biology teacher—who, I later learned, thought I was tripping on LSD—I blacked out and slumped mid-sentence. This happened more than once on my final day awake. But what happened to me could happen to anyone who stays awake that long, voluntarily or otherwise. Unlike other basic bodily functions, such as eating and breathing, we still do not fully understand why people need to sleep.

Others, like Dr. But these theories are not complete. Allan Rechtschaffen, a sleep expert and a professor emeritus at the University of Chicago, told the New York Times in Steven Feinsilver is a pulmonologist and sleep specialist who said that humans need, on average, seven and one quarter hours of sleep to stay healthy. Sleep deprivation is nearly as misunderstood as sleep itself, but it can physically and mentally harm people in myriad ways.

Losing sleep can cause hallucinations, psychosis , and long-term memory impairment. Some studies have linked sleep deprivation to chronic conditions like hypertension , diabetes , and bipolar disorder. In , neurologists at the University of Pennsylvania found that sleep deprivation over three consecutive nights in the study , staying awake for 88 hours as well as chronic sleep loss in the study, four to six hours of sleep each night for 14 nights seriously impaired cognitive functions in healthy adults.

In , at the University of Chicago, researchers observed rats which died after being kept awake non-stop for several weeks. According to a Slate article , specialists who have looked at the study dispute which effects of sleep deprivation ultimately killed the rats.

It could have been hypothermia brought on by decreased body temperatures, illnesses that arose from damaged immune systems, or severe brain damage. In July , Chinese soccer fan Jiang Xiaoshan died after staying awake for 11 days to watch all of the European Football Championship.

In August, a Bank of America intern died after three days of sleep deprivation. Feinsilver directs the Center for Sleep Medicine at Mt. More than 30 years ago, Feinsilver learned first-hand the toll that sleep deprivation can take. One autumn, when he was an intern in an intensive-care unit, he had to work through every other night for six straight weeks.

When I tried to stay awake for as long as I could, I was an aggrieved, angst-filled teenager. I did it to show that I could, to prove something about myself, and to conquer some adolescent frustrations. I felt that I did not have much time on Earth, and death scared me. I did not really believe in an afterlife, and my fears made me wish I had more hours and years to live. Needing to sleep a third of each day bothered me, and I started staying up late to watch television, read, and write.

Eventually I was only sleeping four or five hours each night. One day, I told myself, I would prove how much time sleep stole from us by staying awake for as long as I could and documenting everything I did and accomplished.

I imagined that when I could not take it anymore, I would pass out, then sleep long and deep to make up for the extra time awake, and that would be the end of it.

And nobody does. A sleep-deprived person recovers from sleep loss similar to a traveller recovering from a flight; she spends a certain amount of time tiring out her body and can rehabilitate with an equivalent or duplicative amount of recovery time.

For each hour spent in a plane, a person needs approximately the same number of days to fully recover from jetlag. Researchers like Feinsilver and Walseban fear that this affect has been widespread. At the time, he said, people erroneously thought that sleep apnea was caused by problems with those signals. The research gripped him enough that that he decided to open his own sleep lab.

Today, although his focus remains on sleep problems associated with breathing and the lungs, he continues to investigate the other negative effects that sleep deprivation has on the mind and body.

People that regularly sleep those seven and a quarter hours have been shown to live longer than those who routinely sleep less or more. He added that lack of sleep disrupts other systems in the body. Both Feinsilver and Walseben, whose background is in biopsychology, said that these interruptions, as well as the aforementioned neurotransmitter disturbances, can disrupt reaction times and concentration.

Walseben noted that certain famous historical accidents—such as the the spill of the Exxon Valdez oil tanker —were caused by sleep deprived workers. More recently, a Metro North train in New York may have derailed when a sleep-deprived engineer nodded off at the helm.

Feinsilver said that lack of sleep is also a leading cause of automobile accidents, mainly because when the brain is deprived of sleep, it becomes particularly difficult to perform prolonged, repetitive tasks like driving. While a person sleeps, her cells undergo a cycle of repair that provides both oxygen and glucose. He said that without sleep, the blood gets clogged with substance S, slowing a person down from head to toe.

While I was awake in Europe, my reaction time was horribly off and my ability to concentrate fell apart, and I became increasingly clumsy and weak. Today, I still feel like I have more difficulty concentrating than I did beforehand. It might just be my imagination. Nevertheless, all experimental subjects recovered to relative normality within one or two nights of recovery sleep.

Other anecdotal reports describe soldiers staying awake for four days in battle, or unmedicated patients with mania going without sleep for three to four days. The more difficult answer to this question revolves around the definition of "awake. We all know about the dangerous, drowsy driver, and we have heard about sleep-deprived British pilots who crashed their planes having fallen asleep while flying home from the war zone during World War II.

Randy Gardner was "awake" but basically cognitively dysfunctional at the end of his ordeal. In the case of rats, however, continuous sleep deprivation for about two weeks or more inevitably caused death in experiments conducted in Allan Rechtschaffens sleep laboratory at the University of Chicago.

Two animals lived on a rotating disc over a pool of water, separated by a fixed wall. Brainwaves were recorded continuously into a computer program that almost instantaneously recognized the onset of sleep.

When the experimental rat fell asleep, the disc was rotated to keep it awake by bumping it against the wall and threatening to push the animal into the water. Control rats could sleep when the experimental rat was awake but were moved equally whenever the experimental rat started to sleep.

The cause of death was not proven but was associated with whole body hypermetabolism. In certain rare human medical disorders, the question of how long people can remain awake raises other surprising answers, and more questions. Morvans fibrillary chorea or Morvans syndrome is characterized by muscle twitching, pain, excessive sweating, weight loss, periodic hallucinations, and severe loss of sleep agrypnia.

Michel Jouvet and his colleagues in Lyon, France, studied a year-old man with this disorder and found he had virtually no sleep over a period of several months. During that time he did not feel sleepy or tired and did not show any disorders of mood, memory, or anxiety. Nevertheless, nearly every night between and p. The extreme deprivation associated with FFI results in organ failure and degeneration of parts of the brain.

Up to 22 million Americans may be suffering from sleep apnea. This disorder occurs when your airway becomes blocked, reducing or eliminating airflow. People with this condition can wake up several times per night, causing severe sleep deprivation if left untreated.

Common causes include obesity, large tonsils, endocrine disorders, heart or kidney failure, genetic disorders, and premature birth. If you have this, it can also negatively affect the quality of rest that your partner gets. Restless legs syndrome RLS is a nervous system disorder that creates an uncontrollable urge to reposition your legs.

Children experience night terrors. Unlike nightmares, night terrors are more like a hallucination that lasts anywhere from a few minutes up to 30 minutes. For example, while most scientists agree that the REM cycle is necessary for survival, there are cases of people who have sustained brain injuries that deprive them of this cycle.

There is an anecdotal story of a young man in China who forced himself to stay awake and died after 11 days, but there were other factors involved. The ethical dilemma involved in testing these boundaries is too great to define a specific timeline.

After several days of not sleeping, your organs begin to shut down, and sections of your brain will degenerate. While every person is different, on average, you can expect to start hallucinating after 72 hours of deprivation.

It may be tempting to try to trick your body into staying awake.
