Other scientists say that yawning stretches the muscles and lungs and increases the heart rate, helping us to stay more alert Most people seem to agree about one thing, though... yawning is contagious! Even animals and unborn babies yawn!

COUGH

A cough is an Important way of clearing your airways, throat and lungs of irritations. When you cough, you breathe in and close your vocal cords. As you release the air, you make a barking noise cough. a

We can't help it, but we all sneeze, yawn, blush, hiccup, cough or even snore from time to time. But what exactly is going on in our bodies when we do all these things?

BLUSH

It's no secret that we blush when we're embarrassed, but why? Well, when you feel Belf-conscious, your body releases adrenalin which increases the blood flow to your face. Babies don't blush. You only blush when you become aware of other people's thoughts and feelings.

HICCUP

HI G HIL HIC

When something such as dust, pollen or a virus initates the inside of our nose, a message goes to the brain. The brain then tells six different muscles including your eyelids to push air out through your nose at up to 100 mph.

SNORE

We get hiccups when something irritates the diaphragm muscle below the lungs that helps pull air into them. When we eat or drink too much, or when we feel nervous or excited, the diaphragm pulls down air in a Jerky way. When this air meets your voice box, you make a hiccup sound.

SHER-CHOO! SNEEZE

When you are asleep and air can't move freely through your mouth or nose, parts of your mouth and throat vibrate and cause snoring. Reasons why the air can't get through might include an allergy, a cold or being overweight. Studies say that about 45% of men and 30% of women snore regularly.
