Well, if you do, then you cannot possibly be further from the truth. Until recently many researchers used to think yawning is essential to increasing the oxygen intake to the lungs. A few on the other hand insisted that yawning is similar to stretching as it increases blood pressure and heart beat rate.</p> <p>While both research findings are correct, new studies show that yawning actually perks you up instead of doing the opposite (as many of us seem to think). Scientists point out that we have a tendency to yawn before a big event – athletes yawn before a race, pilots yawn before take-off and you yawn before an exam.</p>
