Lack of sleep may cause you to become lonely without sociality

A cycle of becoming more isolated without approaching people.

When the amount and quality of sleep are disturbed, it is not good for the mind and body.In particular, depression, anxiety, loneliness, etc....Have you ever experienced negative emotions due to lack of sleep?

There are several papers that have shown that "loneliness will be lacking in sleep", but there are not many research that examines whether sleep deficiency can cause loneliness.Meanwhile, the research team was conducted by the University of California Berkeley.According to them, lack of sleep also affects our human relationships.

In a study of 18 student volunteers without health and sleep problems, the following experiments were conducted.

They first are asked to participate in two sessions.One is to put on a sleep activity measurement device and get sleep as usual at home, and the other is to have you stay all night with a monitored lab in a state of "do not sleep."

In both sessions, the subject answers questions such as "calmness in the heart" or "how do you feel" the next morning, and performs two types of tasks (described later).After that, I participated in a 20 -minute interview shooting to look back on a series of experiments.

Two types of tasks were divided into "real" and "virtual".First, a "real" task.The volunteer subjects approach the same sex, which stands about 1 meter away, and stops where the subject feels uncomfortable.This time, the same sex approaches the subject and stops where the subject feels uncomfortable.And the scenario of trying the same thing even in the opposite sex was repeated.In the "virtual" task, similar brain activity is performed with MRI.The subject was watching a virtual thing and a video that people approached, and signaled when he felt uncomfortable.

From both experiments, we found two things about those who stayed up all night.One is that they seek more personal space (space that feels uncomfortable when approached by others).The other is that he tended to feel lonely compared to those who had sufficiently sleeping.But that's not the end.

Researchers recruited another volunteer on Amazon Mechanical Turk and worked on the next experiment process.Subjects report their two -day sleep pattern, calm down their hearts, and how they feel.Subjects who slept in a bad night in the two -day night tended to feel lonely than those who slept on both nights.

Finally, the subjects watched the interview video of the student volunteer earlier and evaluated how their personality (loneliness, social needs, and activity) could be seen.There is no student volunteer information, including how much sleep you have been sleeping the night before.

As a result, it was found that people with lack of sleep are often seen in non -sociable.Interestingly, when I asked the subjects of the interviewer after watching the interview video, I found that I felt lonely and answered that I became self -disgusted.

Eti Ben Simon, a co -author and a researcher at the California University Berkeley School, and a researcher at the University of California, explained to the results of this research as follows:Gave me.

First of all, the weakness of the lack of sleep for people with lack of sleep can deepen social isolation due to lack of sleep.

Second, the immortal effect of loneliness to others will spread to others who are in contact with a lack of sleep, further expanding lonely and social isolation.

It was shown that sleep deprivation not only affects mentals, but also related to the increase in people's loneliness.However, the negative emotions of those with lack of sleep seemed to have not necessarily related to social isolation, as the relationship between loneliness and feelings of descent and anxiety was not confirmed.

If you have experienced a shortage of sleep, you should be aware of how much it would be to spend the day the next day, and how much it would be to get in touch with people until you return home.

However, according to the results of the brain scan of volunteer subjects, it seems that more subtle changes were taking place in the brain.In the case of lack of sleep, it showed a high nervous activity in the "part in charge of the threat" in the brain, indicating that the nervous activity of "the part that understands people's feelings and behavior" was significantly reduced.It is.

This paper must be taken as one of the research results, even if the sample size of the experiment for student volunteers.However, the authors seem to think that if the relationship between sleep and loneliness is verified by more research, it will have a significant meaning.

It is said that as we get older, we have sleep problems and become more likely to feel lonely.One survey also reports that modern young people have a shorter sleep time depending on their smartphones, and one study has recently pointed out that the mental health problems of young people, such as depression, have increased in recent years.If your sleep deprivation causes or results in mental problems, such as loneliness, you will need to hurry to take measures (there are also research that suggests).

Ironically, it is often thought that "sleep hinders social exchange opportunities."Because sometimes, social gathering must be refused to secure sleep time.

(With the results of the research), the opposite is now possible.Sleep will lead to social exchange with our friends, colleagues, family, and strangers.We hope that this will be a good opportunity for you to close Facebook and fall asleep for you.
