Decode the phenomenon of not sleeping in a strange bed

A new study shows that the brain is still active for the purpose of monitoring if sleeping in a new space.

The Foxnews website reported that scientists conducted three experiments on 35 young volunteers. They measured brain activity for two consecutive nights of sleep in the new space. They found that the left part of the brain is more active than the right side, especially during the deep sleep phase, called the sleep phase.

"When you first sleep in a new place, part of one side of the brain always seems to be active for surveillance purposes. So you can wake up faster if necessary , " study author Yuka Sasaki of Brown University said. But the researchers also said sleep would catch up if you slept there for a few more days.

To understand how the new site affects sleep, Sasaki and colleagues performed a series of lab tests. On the first night, they stimulated the left hemisphere with a beep in the right ear who was sleeping deeply in the new space. These people reacted, woke up and got up very quickly.

The second night, they did the same experiment but the reflexes were no longer as fast as the first night. This shows that sleep will gradually get used to the new space . Researchers also say that this is similar in some birds. Several species have been found to sleep in one eye and one side of the brain is alert when they are in a dangerous environment, and some other animals have similar abilities.

The drawback of this study is that it only works in healthy volunteers, and people who have insomnia or sleep disorders are not. Researchers say more research is needed in the hope of finding out about the risks of sleep disorders and insomnia in order to treat the disease.
