Why Yawning spreads person to person?

Why yawning spreads person to person
We often wonder why Yawning is spreading person to person. If someone starts yawning in a group, everyone starts following without any command. But, why is it happening? Research shows that yawning is a reflex caused due to excess of carbon dioxide and lack of oxygen in the blood. Our brain stem detects this and triggers the yawn reflex by its non vital nuclei in medulla oblongata. Neuroscientists believes that yawning spread due to the stimulation caused by mirror neurons in our brain when we see others yawning.

Some scientists opine that yawning helps to regulate our body temperature. Yawning is also caused by some chemicals produced in human nervous system known as neurotransmitters. If the quantity of these chemicals exceeds the optimal level in the brain, it causes yawning. There are beliefs that the contagious yawning associated with social bonding related to empathy.

The biological statement says yawning spreads due to herd instinct. This is nothing but a social tendency in humans to identify behaviour and follow them in a group. It is sometimes referred as “Following the herd”. This is nothing but an act, if someone did something; the others follow the same way. Interestingly, we can’t see this contagious behaviour of yawning among kids below five years old.

The contagious yawning has been observed in dogs, cat, chimpanzees and almost all animals. Feel free to yawning, there is nothing to stop.

  2. Herd instinct - so is it pack instinct when my dogs yawn and then I do also? See, even the suggestion of yawning just made me yawn.

  17. What a cute photograph. There is so much research done on yawning these days. I do agree that it is interesting how it spreads from one to the next. It is like a cough as well one will start and soon the room will be coughing.
