The most common excuses I have heard for yawning....

an involuntary reflex by the body to control the levels of carbon dioxide and oxygen in the blood.

a yawn draws more oxygen into the lungs through a deep breath.

typically this happens after periods when the oxygen level is low as we have been taking short shallow breaths... bordom or fatigue


1. yawning like that is a symptom of asthma, which can appear at any age.

2. it's a natural response to replenish air in the lungs.

3. that it aids in the release of lactic acid that builds up in your muscle while exercising

Physiologically, yawning boosts your blood pressure and your heart rate. It's well documented that Olympic athletes often yawn before competition and paratroopers yawn before a jump.

In the animal world, yawning is often a response to stress. Watch your dog. When she's really excited, she'll yawn a lot. Dogs use yawning as a "calming signal," a way to tell other dogs--and people--that they're feeling anxious and need a break. Some experts believe stress can stimulate a similar reaction in people.

This could explain why we yawn while working out.
Our bodies are being pushed to the limits and our heart rates are increasing like it does when we are anxious.
Maybe the reason that it occurs in some not others
is due to the body misunderstanding the secretion of its hormones
or an incorrect hormone is being secreted when working out
the same hormone that is secreted when we are stressed/anxious
usually CORTISOL
When your body is under stress the Adrenal Medulla releases Adrenaline or Epinepherine
to balance the hormones that were released
Cortisol is pumped through the Adrenal Cortex
cortisol is usually a result of the "fight or FLight" response in our bodies

So Hypothetically....what if yawning has to do with the body misunderstanding its demands going into fight or flight?

i will do more research, so time will tell

damn you got me forming hypotheses at 645 am on a Sunday

BE WARNED: non-stop yawning is a possible sign of an underlying vasovagal
(heart rate andblood pressure) problem.
So, call your doctor and set up an appointment.
You can help him diagnose your condition by tracking how often you're
yawning each day, how much sleep you're getting, and what medications
(including herbs and over-the-counter drugs) you're taking.
