Many people like to yawn because it relaxes them, and individuals indulge in this activity not only in the morning, but also at any time of the day or night.
There is nothing strange in the fact that a person can suddenly yawn, because in this way he allows his body to quickly perk up.
But what to do if a person constantly yawns? Should you try to restrain your impulse?
Why, if a person wants to yawn, should he do it?
The brain is overheating
First of all, a person needs to yawn in order to cool his brain and protect it from high temperatures.
Brain temperature is influenced by the duration of mental activity, its intensity, and the surrounding environment.
When a person yawns, he inhales air, which helps his brain to be enriched with oxygen, and "ventilation" occurs faster. After some time, a person can notice that his mental abilities have improved, the same can be said about his concentration.
This is why a person sometimes wants to yawn if he concentrates on some information for a long time or brainstorms.
Lack of oxygen in the blood
When a person takes a deep breath, it improves blood flow throughout the body and supplies it with oxygen.
If a person does not have enough oxygen in the blood, he may feel a loss of strength, constant drowsiness, he cannot do anything serious, he constantly tries to take a nap.
This is why, if a person sits idle for a long time, he wants to yawn.
Tension doesn't matter whether it's emotional or physical.
In fact, yawning is a habit not only of humans, but also of some animals. For example, lemurs may start yawning if they feel unsafe.
Yawning helps these animals become more attentive and thus protect themselves.
Some animals may yawn after a successful hunt - this allows them to relax and feel a slight euphoria.
