When we stay with a friend or in a hotel room, it is very difficult to fall asleep that first night. Because we find our place strange. We even get angry with ourselves for this reason. Why can’t we sleep in a very comfortable place?
Doesn’t that sound quite strange? In fact, aren’t a comfortable bed, ideal room temperature and a quiet environment all you need to fall asleep?
Enter, Let’s see why we find it odd.
In fact, this peculiarity is known as the first night effect and is a type of sleep disorder.
According to scientists, this situation It may be an involuntary defense mechanism. Studies were conducted in which the changes seen in the brain and body during sleep were recorded and analyzed with a device and different brain imaging techniques were used.
In these studies, when we sleep in a new environment, It was understood that the activity in the left hemisphere of the brain was higher than the activity in the right hemisphere. Additionally, more neural activity was observed in the left hemisphere, with decreased 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 like a night observer.
According to scientists, it is quite possible that the first night effect is an adaptation mechanism necessary to survive 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 brain..
Among the ideas thought to be the answer to this question are the left brain, Functional connections between brain regions are stronger than in the right brain.
