Question

Why is it that when you see someone yawn it makes you yawn..???

Answer 1

Yawning is essentially a reflexive method of increasing oxygen intake. Oxygen intake in this manner is primarily used as a means to stay alert. Yawning may be an arousal response that arose early in evolution and whose aim is to improve oxygenation of brain tissue and increase alertness, with a view to enhanced survival.

When we observe others yawn it triggers a warning to ourselves that we are in a situation where we need to be alert, hence the infectious desire to yawn yourself.

Hope this helps !
