Many people have an experience that they keep yawning and almost fall asleep during driving. In order to prevent people falling asleep during driving, they either drink coffee as a stimulant or wind down the window to the wind blow into the vehicle. However, such methods are not the best solution to solve the above problem since the coffee contains caffeine that makes people uncomfortable, such as speeding up the rate of heartbeat or causing the hand shaking. In addition, it is a hassle for the passengers when the windows are opened.
In order to solve the problem that causes the people sleepy, scientists have discovered that when people are in a drowsy condition, the body temperature, especially the upper head portion, will be raised. Once the body temperature is raised, the nervous system of the human's brain will start slowing down the response so that people will function sluggishly. Therefore, most drivers would like to park their vehicle aside and wash their faces to cool down the body temperature when they are sleepy. In other words, when the body temperature increases, the working efficiency will be reduced.
Furthermore, the regulating system of the human being cannot automatically cool down the body temperature while the body temperature is raised again. Therefore, people will tend to return to the drowsy condition again such that they must repeatedly wash their faces to keep them awake.
