7 Awful Effects of Sleep Deprivation
Around half of the adults in the US said that they don’t get enough sleep each night. According to studies, sleep deprivation is connected to several problems, such as health problems and increased chances of vehicle crashes.
It was only recently when scientists took a closer look into sleep deprivation. New tools have helped them improve sleep research in the past decade. The field is still too young to have definite conclusions, and there are some questions that remained unanswered, such as why do people dream?
There are researchers who conduct sleep deprivation studies to find out what happens when people lack sleep. Some of their subjects are asked to go without sleep for a night, while others have restricted sleep schedules that last for several weeks.
Studies have already indicated that having no sleep during the night can reduce one’s attention span, cause memory problems, and decrease reaction time. Sleep deprivation can also increase the levels of the hunger hormone ghrelin. Sleep has been connected to a wide range of functions human use daily, and the lack of sleep can mess them up.
During the 28th meeting of the Associated Professional Sleep Societies, researchers shared their preliminary results on the effects of sleep deprivation. These include becoming less sensitive and empathetic to gambling losses. The researchers said that most people don’t even realize that they are deprived of sleep.
You should consider that the results of the research were only preliminary, and more research is needed for further conclusions. Below are the seven bad side effects of sleep deprivation.
Sleep-deprived people don’t know they are sleep deprived.
Sleep-deprived people thought that they were doing well in reaction time tests conducted by the researchers. Their test results showed that people who lacked sleep do badly on the tests. The results didn’t surprise them, but the lack of awareness of their condition did.
Sleep deprivation gives people sleep goggles.
In one of the experiments, results showed that men rated photos of the least attractive models as being more attractive. The effect was not seen among women. In a previous experiment, results showed that men think women want to have sex with them.
Sleep deprivation increases pain sensation.
A study conducted by a group from the Komoki Sleep Center in Seoul, Pusan Nation University Yangsan Hospital and the University of Sydney suggested that the tolerance to pain became lower with less sleep at night.
Sleep deprivation makes people less concerned.
Researchers have studied the empathy levels of subjects and seen how sleep-deprived people tend to be less empathetic when looking at hands stung by needles.
Sleep deprivation leads to an increase in delusional beliefs and paranoia.
People who had been awake for 18 hours straight scored higher on the standard tests of global paranoia. People lacking sleep rated higher on depersonalization or feeling separated from one’s thoughts, reality or body.
Sleep deprivation makes people less concerned about money.
People who lack sleep should not be gambling, according to one study conducted by researchers from the University of Pittsburgh. When sleep-deprived people were expecting to lose money, their brain showed less activity in the regions that are connected with the mind’s reward system.
Sleep deprivation prevents people from recognizing emotions of others.
People who lack sleep don’t know the emotions showed by other people. Researchers found out that the lack of sleep makes people concentrate on the lower part of the body.
