What's the reason for yawning all the time

First of all, yawning is an instinctive reaction of human body, just like heartbeat and breathing, which is not controlled by human will. It has a good protective effect on protecting brain cells, increasing the oxygen supply of brain cells and improving the stress ability of human body. At the same time, it is also a reminder that our brain is tired and needs sleep, so yawning is also a hypnotic method.

Second: people will often yawn before they are about to enter the intense work. This may be that the human body increases more oxygen in the blood with the help of deep inspiration, improves the activity ability of the brain, so as to better enter the working state.

Third: when there is a continuous yawn, you can also take several deep breaths to expel carbon dioxide from the body.
