Yawning is such a common phenomenon in one’s life that hardly any attention is paid to it. Usually yawing is connected with dullness or sleepiness but in reality it is a much more complex and difficult phenomenon to understand. There are a number of theories which are linked up with yawing. Some of them are that a person yawns due to sleepiness, boredom, oxygen scarcity, removal of bad air from lungs etc. But according to many of the new theories, yawning has not much to do with the respiratory system (Buttner & Strasser, 2014). Even the function of yawning in a human body is not much clear. According to few scientists, yawning increases the amount of oxygen in blood; it elevates the heart rate and also brings in some escalations in blood pressure. This results in making the organs of the body more active in case they have been inactive since a long time.

Yawning is a complex function of brain which is difficult to understand and draw one conclusion. A lot of studies have been done to understand the exact reasons behind the act of yawning in human beings and different experiments prove or support different hypothesizes. In this essay there will be a detailed discussion on various theories and hypothesis related to yawing and its functions related to human behavior.
