Question

whenever we feel Drowsy sleepy we started yawning
does yawning help us in anyway

Answer 1

✌️✨HLO THERE UR ANSWER IS...

One is that when we are bored or tired,we just don't breathe as deeply as weusually do. As this theory goes, our bodies take in less oxygen because our breathing has slowed. Therefore,yawning helps us bring more oxygen into the blood and move more carbon dioxide out of the blood.

HOPE IT HELPS...

Hey there mate!!  The correct answer is  When you feel sleepy..it is actually the brain cells which are in a sense of saying..going to fall asleep for lack of oxygen Also when we feel drowsy, our respiratory rate being controlled by reflex centres in our brain falls. This is a vicious cycle. The yawn breaks this cycle.  Hope it helps you! ヅ  ✪ Be Brainly ✪
