Question

why do we yawn?????????????​

Answer 1

Answer:

One is that we are BORED or TIRED, we don't breathe deeply as we usualy do.

Explanation:

Our body takes in less oxygen as breathing has slowed down.It helps to bring more oxygen into the blood and move more carbondioxide out of the body.

Answer 2

$\huge{ \purple{ \underline{ \textsf{ \textbf{Answer}}}}}$

When we are sleepy or drowsy, the lungs do not take enough oxygen from the air. This causes an increase of carbon dioxide in our body. The brain senses this increase and sends a message that causes us to take a deep long breath—a Yawn. It brings in oxygen and decreases carbon dioxide content in the blood.
