Response in English: One possible hypothesis to explain why people yawn is that yawning helps to regulate the temperature and oxygen levels in the brain. As people inhale during a yawn, the influx of air helps cool down the brain, while also increasing the oxygen and blood flow to the area. This could serve a function in helping people stay alert and focused, especially when they are feeling tired or fatigued. .
