Why do living beings yawn and is yawning useful? Let's look into this issue.
It is considered indecent when a person starts yawning in front of others. Many people perceive the reason for yawning as either a lack of sleep, or boredom or the annoyingness of the interlocutor.
But according to scientists, it is the yawn that allows us to maintain mental alertness. A yawn cools the brain and allows us to switch to another type of activity.
Moreover, it is even recommended to consciously use yawning.
Yawning before bed relaxes and calms, helps you fall asleep faster, and in the morning it affects the speed of brain activation.
It has been scientifically proven that yawning significantly increases brain function and increases blood flow to the brain.
A significant increase in brain temperature occurs when performing complex intellectual tasks, and the blood sent during yawning lowers its temperature.
But is it possible to use yawning, as they say, to good use? It turns out it is possible:
Yawning a few times before a speech, exam, etc. will improve your concentration.
Yawning will be a good helper when changing time zones and biorhythms, when acclimatizing at altitude. You need to do about five yawns.
A deep yawn and stretching will help your body relax significantly. And as a result, after a few deep yawns you will fall asleep faster.
Yawning can also help improve your mood, as it is directly related to an increase in dopamine levels, a neurotransmitter responsible for pleasure, activity, etc.
Yawning can be controlled, it is not an automatic action.
We all know how contagious yawning is: one person yawns and immediately another starts yawning.
But you can learn to force yourself to yawn. You need to slow down your breathing. Yawning will cause a significant decrease in oxygen intake. Yawning will also be facilitated by the expansion of the nostrils when inhaling.
The best yawn is considered to be a fully felt yawn with the mouth opened as wide as possible. At this moment, the maximum tension of the facial muscles occurs and an extremely deep breath is taken.
