Lack of sleep and fatigue can change the "personality" of a person becomes irritable and more annoying. Actually, why it happened?
In the Journal of Applied Social Psychology, the researchers explain that the lack of sleep will lead to self-control and ability to think clearly diminished. In addition, lack of sleep also reduces the body's ability to deal with stress.
The less time off, the more difficult for you to judge what is right and wrong. I wonder if the people who are sleep-deprived become more vulnerable to depression.
When lack of sleep, the process of thinking, remembering, and learning to be disturbed. This will cause a person's mood became so chaotic behaviors appear so easily offended. They also become difficult to make a decision.
"During sleep, the body actually saving energy. At the cellular level, a process of improvement. If the process is interrupted, we can not do the things we want, both physically and mentally," says Barry Krakow, sleep expert.
According to the Medical Director of the Sleep Medicine Center Martha Jefferson Hospital Christopher Winter, the study showed an increase in amygdala activity when sleep time is reduced. The amygdala is the part of the brain that regulates emotions, such as anger.
"The way the brain communicates with the amygdala after sleep deprivation in the long run not only encourage the emergence of negative emotions, but also makes us unable to control bad feelings," said Winter.
In children, lack of sleep will also interfere with their control of the emotions and impulsivity. Children who are tired and lack of sleep are generally more frequent rages (tantrums) compared with children who get enough sleep.
