We all have figured out one thing about yawning- it is related to our tiredness. Science and studies shows some facts about yawning.
Let’s check out these amazing 5 facts about yawning.
Yes, it is contagious!
It is absolutely true that watching someone yawning triggers your yawn. Studies show that yawning is a contagious phenomenon. Even if one is blind, the sighing yawning sound can make you yawn. A 2004 study about yawning shows the transferable nature of yawn in animals. Contagious yawning can be frequently observed in animals like chimpanzees, baboons, snakes, pigs and crocodiles.
Is yawning related to our tiredness?
Yes, yawning is somehow related to your level of boredom. A recent study about yawning shows that it is more related to brain cooling. A person yawns more in winters than in summers. The reason is to bring the cooler exterior air inside our body and winters are more cold. When we stretch our mouth while yawning, the sinus walls expand and contract more. This brings more cold air into our body. This process is helpful in cooling down our brain.
Yawning can also signify a disease
Yawning is a natural phenomenon in humans. This process is considered as a response of our body against boredom and tiredness. But, excessive yawning can be a sign of disease. Frequent yawning can be due to sleep deprivation, insomnia or sleep apnea. Anxiety can also trigger disturbed sleeping patterns and results in fatigue and yawning. Anxiety inhibits our energy levels and affects our heart. Depression can also result in drowsiness, sleep deprivation and yawning. There are certain medications that can also trigger excessive yawning.
Yawning is an ear pressure equaliser
Yawning can prevent the air pressure problems in our ear and relieves pain. Due to rapid air altitude changes in airplanes and elevators, air gets trapped in our middle ear. The contraction and relaxation process of yawning opens the eustachian tubes.This process equalizes the air pressure in our ear with atmospheric air pressure.
Yawning and Social Relations:
Your closeness with someone special can trigger the yawning phenomenon most rapidly. Recent studies show that yawning is associated with your empathy levels and social bonds. The more close bond you share , the more you are more subdued to yawning. A dog owner can pass their yawn to their dogs. Close friends, love birds and family members can transfer their yawns more strongly than others.
Yawning is the most common phenomenon which is least understood by science. We all do it but no study can totally explain this process. A simple yawn has lots of biological mysteries and facts in it. We have tried to discover a few of them. We hope that you will find these facts useful enough to suffice your curiosity about Yawning.
