Yawning is an action associated with sleep. When we yawn, we realize that we are sleepy and that it is time to go to bed.

But in the morning, Even if we wake up feeling sleepy We yawn. What could be the reason for this?

Body temperature and blood flow are regulated.

Many of us feel cold when we wake up. When we yawn, we breathe in more air. by expanding our lungs We increase our body’s oxygen level and accelerate blood flow. This is how our body temperature is regulated.

Even if we don’t realize it, we are preparing the muscles and joints for the day.

Remember that we lie virtually motionless all night when we yawn Our muscles and joints relax and become activated gets ready for action.

We activate both our brain and our body. Think about the first moment you woke up. Your brain is not very functional, we become a bit ‘commodified’. When we yawn The speed of brain cells increases with blood circulation and energy levels rise.

The biological clock also has an effect.

After waking up, our circadian rhythm (biological clock) ensures that our brain and body stay in sync. activation signals like machines send. These signals can trigger yawning to increase muscle and brain activation.

In short, yawning does not only happen when we are sleepless, It prepares our body for the new day.
