Yawning causes: Why does yawning occur? Know the scientific reasons for yawning, what is its connection with it, from cooling the brain to sleep, fatigue and boredom. Also read 5 interesting and lesser known facts related to yawning.
Yawning is a natural process of our body. In this, a person takes a deep breath by opening his mouth wide and then exhales slowly. Apart from humans, this process also occurs in some animals like dogs, cats, monkeys and lions. People believe that yawning occurs only due to sleep or fatigue. But according to science, there could be many other reasons behind this.
1. When the mind needs to cool…
According to a famous theory of science, the function of yawning is to control the temperature of the brain. When we yawn, cold air goes inside our body. This reduces the temperature of the brain a little and we feel more refreshed. For example, if you continuously study or work on computer for a long time, then suddenly you start yawning. This may be due to mental fatigue and the need to reset the mind.
2. Lack of sleep and fatigue
This is the most common reason. If you have not had enough sleep or the body is very tired, the brain gives an alarm for rest. At this time yawning occurs again and again. For example, after less sleep at night, it is common to yawn repeatedly in office, school or college.
3. Boredom can also be the reason
When any work is done without interest for a long time, the activity of the brain starts decreasing. Yawning also occurs at such times. For example, many people yawn continuously during long and boring meetings, lectures or travels.
4. Why do we yawn even after looking at someone else?
This is called Contagious Yawning. If someone yawns in front of you, sometimes you too start yawning. Doctors believe that it may be related to the mirror neurons present in our brain and social behavior. This is the reason why it is more visible among family, friends or close people. For example, if someone yawns in a room, then within a few minutes other people also start yawning.
