Doesn’t that sound very strange? Aren’t a comfortable bed, an ideal room temperature and a quiet environment all you need to fall asleep?

Bride, Let’s take a look at why we find it strange.

This peculiarity is known as the first night effect and is a type of sleep disorder.

According to scientists, this situation is It may be an involuntary defense mechanism. Studies have been conducted in which the changes observed in the brain and body during sleep were recorded and analyzed using a device and various brain imaging techniques.

In these studies, when we sleep in a new environment, It was clear that activity in the left hemisphere was higher than activity in the right hemisphere. In addition, more neural activity was observed in the left hemisphere, with reduced sleep depth, compared to the right hemisphere, in response to environmental stimuli.

In other words, when we sleep in a dark environment, the left hemisphere of the brain acts as a night observer.

Scientists believe it is quite possible that the first night effect is an adaptive mechanism necessary for survival in an unfamiliar and potentially dangerous environment.
Why does our left brain change when we sleep in a different environment? It is not known exactly whether it is more active than the right hemisphere..

Ideas thought to be the answer to this question include the left brain, Functional connections between brain areas are stronger than in the right hemisphere.
