When we yawn, we open our mouth wide and take a big breath! 😮 It helps our body wake up a little when we feel sleepy or bored. Yawning also cools our brain, like a little fan inside our head! 🌬️
Did you know? Even babies yawn when they are still in their mommy's tummy! 👶
Yawning is our body's way of waking up the brain! 🧠 When we're tired or bored, our brain gets a little slow, and yawning helps bring in more oxygen to make us feel alert. It's like pressing a 'refresh' button! 🔄
Yawning is also contagious—seeing someone yawn can make you yawn too! Scientists think this might be a way our brains help us feel connected to others. 🤝
Yawning is a complex reflex that serves multiple purposes. One theory is that it helps regulate brain temperature by bringing in cool air. 🧊 Another is that it increases oxygen levels in the blood, especially when we're tired or stressed. Yawning might also help equalize pressure in our ears, like during flights! ✈️
Contagious yawning is linked to empathy—people who yawn after others often have strong social awareness. Studies show even dogs yawn when their owners do! 🐕
