This is the answer to why you always find it difficult to sleep when you put your back in a strange place

This is how the brain guards and protects your own safety.

We often find it difficult to sleep in the first night in a strange place. This case is called the medical term "slow hemispherical sleep wave". Aquatic mammals such as bottlenose dolphins, or white whales also use this tactic to maintain a hemisphere in a state of alertness and maintain respiration.

You may only encounter cases where people use this ability in science fiction novels or movies. But, this phenomenon is extremely common in practice: when we sleep in a strange place, we will have a "semi-conscious" phenomenon .

Every time we sleep in a strange place, we will have a "semi-conscious" phenomenon.

In a study published in Current Biology, Brown University researchers studied 'first night effects' by tracking the sleep of 35 volunteers for 2 consecutive nights. And as in the wonderful sci-fi stories, the left hemisphere of the left and awake throughout the first night for a bad watch can happen.

Not only is the watchful function, the left hemisphere is also the culprit causing anxiety and anxiety every time you think about a negative event in the past or a possible future threat. . However, in the study, the volunteers did not show strong anxiety. So, finding a strange place to sleep is sometimes a method to relieve anxiety, helping the left hemisphere to relax.

Brown University researchers believe this is a completely new research topic for people. So there are many unexplained questions. They have only discovered four left hemispheres' neural networks that function in this task. But is the left hemisphere the only night guard? Does the right hemisphere have a role to play in this mission? And if so, why does the left hemisphere perform this function before the remaining hemisphere?
