Nobody is able to disagree with the fact that people need to rest. Studies have linked a lack of rest to everything from disruptions in the immune system to cognitive deficits to loss of weight control. Psychological problems have also been linked to long-term sleep deprivation. There have been many researches which can prove that sleep deprivation and psychological disorders are closely connected.
Psychological difficulties are the leading cause of insomnia, the medical condition when a individual loses the ability to have a good night’s rest. Studies have also proven that sleep and psychological disorders such as schizophrenia and depression are closely related. Similarly, people with psychological disorders have other sleep deprivation causes, including sleepiness during the day, stress, and scary dreams. Lack of sleep can also cause psychological problems such as paranoia and hallucinations. Problems with sleep can make psychological disorders worse by making the person confused or frustrated, as well as more sensitive to pain and other medical issues.
People who are depressed have a tendency to wake up early, and then, they feel that it is hard to sleep again. This can make their depression worse, since the amount of sleep a person gets has an effect on his or her illness and disposition. People who don’t have a psychological disease but suffer from picwickian syndrome are more likely to develop a disorder like depression later in their life.
It’s no secret that a person suffering from sleep deprivation is usually grumpy, miserable, and not much fun to be with. One of the functions of sleep is to reset and replenish the emotional capacity of our brain circuits so we can approach the day’s emotional challenges in appropriate ways. If one doesn’t get enough rest, he or she will be making irrational choices.
Doctors and sociologists agree that Americans are among the most sleep-deprived people in the world. According to a 2005 poll conducted by the National Sleep Foundation, about 40% of Americans get less than seven hours of rest at night and 75% reported having some sort of sleep disorder one or two nights a week.
According to the analysis, insufficient sleep can lead to a loss of concentration and memory and it can make people more sluggish and exhibit slower and less coordinated motor skills. Lack of sleep also weakens the immune system while abnormally boosting activity in some parts of the brain — a factor that is related to a type of psychological disorders. If one does not get enough rest, chances of developing a psychological disorder are much greater, at least, based on research from Harvard Medical School and the University of California in Berkeley (UCLA). The said study indicated that brain scans taken from volunteers show that the sleep-deprived brain becomes tired and abnormally emotional. The Harvard and UCLA researchers had 35 volunteer-participants who did not rest for 35 hours. They discovered massive activity in parts of the brain when they looked at images aimed at making them sad or angry. The researchers, with the aid of fMRI (functional magnetic resonance imaging), were able to analyze the blood circulation in the brains of the volunteers in real time, after and during sleep deprivation. The technology reveals which parts of the brain are experiencing the most activity.
After a long stretch without rest the participants were asked to look at pictures that were created to trigger an emotional response. The scientists further explained that the amygdala showed 60 percent higher response to the pictures compared to people who are not sleep-deprived. The amygdala is a part of the brain which is linked to emotional reactions.
But sleep specialists are hopeful that more study could lead to refined options for relieving not just sleep disorders but psychological problems such as depression and stress. This means that a sleepless night can cause them to overreact to emotional challenges that they would otherwise be able to tolerate with no trouble.
