Why is yawning infectious⁉️
🤔🤔😮
Yawning is a result of increased levels of carbon dioxide in the lungs – often occurring as a result of a lower breathing rate when the body relaxes.
If a group are all relaxing together, it is probable they’ll all reach the same elevated level of CO2 at approximately the same time.
Hence they may feel the need to yawn at the same time.
