Uncultured people are given away by their habits. It is not necessarily a rude person and one who is unable to string a few words together to form a sentence.
That's why they are habits, because they are mostly noticed by those around you.
Here are some habits of a person with low intelligence that manifest in bed.
Reluctance to undress or change clothes before going to bed indicates low intelligence.
It is possible that a person finds this method convenient and fast.
But from a scientific point of view, sleeping in outerwear reduces its quality, which affects brain function.
Having every opportunity to do so, a person tries to go to bed at the same time, that is, adheres to a daily routine.
The lack of a daily routine does not indicate any outstanding abilities.
Rather, it all comes down to the negative impact of the habit on cognitive functions, memory problems, and decreased concentration.
Even if a person manages to fall into deep sleep with the TV on in the background, his brain still cannot fully rest.
The noise of a working TV and the light from the screen interfere with normal rest, which again affects the functioning of the brain.
For reference
A habit is an automatically reproducible action, the execution of which is initiated by some signal, performed and completed with a feeling of pleasure.
