Why do you recognize the bed when you sleep in a strange place?

Many people always toss and turn during long-distance travel, commonly known as "recognizing the bed." Recognizing the bed can explain many phenomena.

A study shows that people who sleep in strange beds usually can't sleep well because half of their brains are still on duty, which is why some people recognize the bed when they sleep. The "first night effect" is familiar to people who often sleep in hotels and sleep researchers. Now, a group of scientists are trying to find out why people often can't sleep well on the first night in a strange environment. A series of brain scanning techniques revealed an amazing discovery: yes, only on the first night, the left side of the brain was much more "awake" than the right side.

The appearance of this phenomenon is often an instinctive consciousness of human beings. In the animal kingdom, some animals can catch prey in their sleep, or sense danger and respond in time. This phenomenon is reflected in people's reaction to Zhichuang. When they first arrived at a place, they were unfamiliar with it. When their brains are relatively nervous, they will recognize the bed. Even some people will wake up in their sleep or often have nightmares, which will affect their sleep. If they are not adjusted in time, their mental state will be relatively poor. This is not good for your health. This is a cold knowledge about sleep that most people don't know.

The researchers found that when the subjects spent the first night in a strange experimental environment, the slow wave activity of the default network in the left hemisphere was lower than that in the right hemisphere, indicating that the sleep depth in these areas was shallower than that in the right hemisphere. This "deep sleep" and "awake" state may be the reason why people can't sleep for the first night. First of all, you should fully relax before going to bed, don't think about some hard and sad things, clear your mind and relax.

So we can explain that sleeping in a strange place will lead to the recognition of the bed, which is caused by the vigilance in everyone's brain.
