- In the seventeenth and eighteenth centuries: Most theories focused on the circulatory system. These theories posited that yawning causes an increase in blood pressure, heart rate, and oxygen in the blood.
- Today: Dr. Robert Provine, in 2005 stated that yawning is associated with changing a state of behavior.
- Gallup in 2008 proposed that yawning is related to a way of cooling the brain's temperature.
- In 2011, Dr. Andrew Gallup and Omar Tonsi Eldakar stated that yawning is related to the outside temperature, that is, when the temperature is warm, the body yawns less frequently.
