Research on yawning goes back to ancient times to Hippocrates. As a result of his research, Hippocrates made observations that yawning helps to clean the dirty air in the blood. During yawning, the mouth is opened wide and a large amount of air is drawn into the lungs, then this air is slowly exhaled. Usually when yawning, the eyes are closed and the eyes tear. In the meantime, the eardrums are also stretched. The stretching movement can sometimes be accompanied by the stretching movement of the body. Stretching takes an average of 6 seconds.
Yawning is a fascinating physical condition, and there are many reasons why. We found 6 surprising facts about something as simple and natural as yawning.
WHY yawn?
Until recently, yawning was thought to oxygenate the brain, but this theory was later shelved. Yawning is often thought to be triggered by an increase in brain temperature that occurs when you are tired, bored, hot, or sick. Yawning has a temperature-regulating effect that allows us to regain alertness. Yawning also increases blood flow and allows cooler blood flow to the brain.
Here are 6 facts about yawning that you probably haven’t heard before.
FETUSES ALSO yawn
The youngest creature to yawn is an 11-week-old fetus. Babies yawn, you know that, but you certainly didn’t know that contagious yawning doesn’t start until the second year of life. The reasons for this are still unknown.
YACHES TAKES 6 SECONDS
Count to six out loud. That six seconds doesn’t take long, does it? Studies have shown that men yawn longer than women. The secret lies in the fact that the volume of the male brain is slightly larger and therefore takes longer to cool.
YACHING COOLS THE BRAIN
Studies show that yawning is associated with brain temperature. We maintain a balanced brain temperature by yawning. Studies show that people yawn more in the summer. This stands out as a natural mechanism, given that yawning cools the brain.
LOWER LUNGS LOVE TO flex
The body does not need a whole lung when resting or doing anything passive. By yawning, we allow air to enter the lower part of the lungs to be functional at rest. This connection between the lungs and yawning has not been fully resolved.
DOGS YACH WITH US
If you treat a dog like a family member, you know the dog does a lot with you. Research shows that dogs that hear their owners yawn begin to yawn.
yawning is contagious between people
Are there people around you right now? Try yawning. After yawning, look around. Half of those who see you yawn will yawn, just as laughter is contagious. No one knows why yawning is contagious, but it is known to be contagious. Did you yawn while reading this text? How many times? We yawned 40 times while writing the text.
