Allow me to "expand on the prier answer!.!.!.!. true a theory is to balance the equilibrium, but the true cause is because the body is lacking in oxygen which it needs to regulate proper blood flow!.!.!. also when you stretch you are actually compressing your lungs, which in turn causes then to make a desperate attempt to expand and take in air which the result is a yawn!.!.!.hope that helps!.Www@Answer-Health@Com

There is a few reasons why people yawn (well at least theories)!. One theory I know of is that people yawn to equal out their equilibrium!. Also, the second theory is that people yawn because it is a large amount of oxygen that we need in the brain (which is caused by the "tiredness")!. I can't explain the body stretching!.!.!. its just feels good!. We do things naturally that feel good!.Www@Answer-Health@Com

Stretching increases blood flow, part of the reason it is good to stretch in morning to help wake you up!. Yawning from my understanding regulates the carbon dioxide and oxygen levels in the blood!.Www@Answer-Health@Com
