Mumbai: People make hi on average 8 times a day … and for about 70% of people, hi is contagious. Just showing a picture or a video of taking a hi, you can also take hi. But researchers say that just saying hi is enough to make you hi.
So let’s not know the possible reasons behind this …
We associate yawning with sleep and boredom. But can you be bored with life before you are born? A human embryo begins to raise during its first trimester. And the fact that it is unintentional means there must be a purpose to this biological reflection. But that purpose has been widely debated since 400 BCE.
Hippocrates believed that high fever was a symptom. The bad air that has accumulated inside the body has to be expelled. Today’s theories are a little more sophisticated, but not confirmed.
You may have heard that lifting hi gives us a big jolt of oxygen-rich air, which enters our bloodstream and helps us when we need it most. This is a myth.
Asthma can be something we do when we are bored, but certainly not always. Olympic athletes are caught breathing before the big event, famous musicians before the concert and Greek berets before making the first jump off the plane.
1. Neuroscientist Robert Provin believes that lifting hi can signal a change in mood. Awakening from sleep, calm from anxiety, alertness from monotony and vice versa.
2. Another top theory came from Andrew Gallag, a professor of psychology, who suggested that high lifting cools the brain. As our most complex system, the brain uses 40% of the body’s metabolic energy. And like any technical device, you may be familiar with, the more energy something takes, the hotter it gets over time.
There are plenty of blood vessels inside your nose and mouth that carry you to the brain. The wide open increases blood flow to the brain and when you raise a high it takes in a large air, cools the way the blood goes up and therefore cools the brain as well.
This may explain why you yell at bedtime and shortly after waking up:
At the end of a long day, your brain temperature and body temperature are at the highest point of the sleep / wake cycle. But this temperature decreases when you sleep and rises when you wake up. So, you sneeze to normalize your internal temperature to keep up with other bodily processes. This theory may be supported by the fact that we breathe more when it is cold outside than hot.
3. Another aspect of raising the hi is that it releases the pressure created behind the eardrum when changing the height. So really, the reason we raise our hi may not be much consensus, but we know it’s contagious.
You shout when the people around you shout. You shout when you see pictures or videos of people shouting. You talk about yawning when you yawn. You cry when you hear people say hi!
Do you know why
Behaviorists believe that this is an early sign of human empathy. Others suggest it may have something to do with room temperature or climate. For now, the exact cause has not yet been determined.
