Yawning is one of the most common and often embarrassing behaviors, especially when it happens in front of the mass or among the elderly or higher cadre people.
Whenever we get bored usually we yawn. Not only you and I; but also most of the animals do yawn. Probably even the birds too. Because each creature is bored and tired!
The science says that yawning helps us to get more oxygen into the blood and remove more carbon dioxide out of the blood. Hence yawning fulfills the need of quick breathing.
Yawning is an involuntary reflex which helps us to control our oxygen and carbon dioxide levels.
There is also another theory that, whenever there is increase of brain temperature, yawning happens to cool it down.
Some others believe that yawning stretches the lungs and lung tissues. Thus stretching and yawning may be a way to flex muscles and joints; which increases the heart rate and feel more awake and comfort.
Quite interestingly, there is one belief which is wide spread about yawning that it is vulnerable when one yawns…or it becomes contagious!
If you yawn in your place of work a few other will also start yawning. Even thinking about yawning can get you yawning! Even though much scientific inputs may not be available to substantiate this finding it appears true in many respects.
What is Yawning?
A yawn is defined as a reflex consisting of the simultaneous inhalation of air and the stretching of the eardrums, followed by an exhalation of breath.
Yawning is most often found immediately before and after sleep and during tedious activities. Engaging in uninterested activities, restlessness, stress, too small room of residence, hunger or thirst may also act as stimulant of yawning mechanism. Some believe that Yawning is a mechanism of cooling of the brain too.
Wall Street Journal explains – “Yawning is believed to be a means to keep our brains alert in times of stress. Contagious yawning appears to have evolved in many animal species as a way to protect family and friends, by keeping everyone in the group vigilant. Changes in brain chemistry trigger yawns, which typically last about six seconds and often occur in clusters”.
Rationality behind Yawning-a scientific outlook-
The author Daniel J. De Noon points out three mechanisms behind Yawning and they are-
- When you start to yawn, powerful stretching of the jaw increases blood flow in the neck, face, and head.
- The deep intake of breath during a yawn forces downward flow of spinal fluid and blood from the brain.
- Cool air breathed into the mouth cools these fluids.
Yawning-may be a feature in some diseases
Yawning may be found as a symptom in few of the diseased condition also. The researchers report that it may be found in the cases where Oxygen deficiency is the significant point in the illness. Recent studies in this regard suggest that Yawning is a feature in the illnesses like-Central sleep apnea, Obesity, Diabetes mellitus, Heart diseases, Epilepsy, Multiple sclerosis, Aortic troubles, Stroke syndrome etc.
Yawning –as explained in Ayurveda
Experts of the science opine that Yawning is a Kapha vataja discomfort (not a disease) caused due to the obstruction to the free flow of Udanavata in the area of the chest. This may be caused due to the obstruction to the free flow of Pranavata also. In such incidences the condition may be vulnerable and if not responded may be critical. It may infer regarding the critical conditions referred by the modern physicians as said in the previous paragraph.
Ayurveda mentions yawning as a side effect of lack of sleep. As per Ayurveda it is a Pranavata activity.
yawning, called Jrumbha in Ayurveda is explained as a – Adharaneeya Vega – natural urges that should not be suppressed.
