A new study has suggested that yawning may be a mechanism the body uses to help cool the brain.
Most people associate yawning with either tiredness or boredom, however it seems it may play a very different but crucial role in the regulation of heat in the brain. Postdoctoral research associate Andrew Gallup also discovered that we tend to yawn at a different rate based on the current temperature and climate.
"Gallup and Eldakar documented the yawning frequency of 160 people in the winter and summer in Tucson, Ariz."
