Yawning helps our body and brain.
Yawning is a natural reflex where we open our mouths wide, take in a deep breath, and then exhale. One idea is that yawning helps bring more oxygen into our blood and sends it to our brain, which can make us feel more awake. When we are tired or bored, our breathing might slow down, so yawning gives our body a quick boost of fresh air. It’s like a little wake-up call for our brain.
Yawning might cool our brains.
Another theory is that yawning helps cool the brain. When we’re tired, our brains can get warmer from working all day. Taking in a big breath of cooler air during a yawn may help bring the temperature down. A more extraordinary brain can think more clearly. That’s why yawning can happen not only when we’re tired, but also when we feel bored and our brain is not getting much excitement.
