Why do we speak out when we see the other person?

We talk all the time, but why? With intuition you'd think there's something to do with your <x0... your” when you're tired, but this theory has proved wrong.

The mouth opening also exists in the animal kingdom, but we don't know why. The most frequent theory is that opening our mouth allows us to absorb a large quantity of oxygen that will awaken us.

There is no evidence that opening the mouth changes the oxygen level in the body, which questions the theory.

In fact, scientists have tried to find a link between mouth opening and heart function but have found very little.

A new theory has emerged that speaks of brain temperature and makes sense.

Your mouth is likely refreshing.

An experiment has shown that keeping a cold bag on your head reduces the tendency to open your mouth. This shows the first mouth - opening and temperature connections.

Dr. Double, has suggested that the opening of the mouth is linked to the rapid growth of children. There are still some dark, inexplicable sides.

The mouth's opening is made up of three stages: deep breath, open mouth, followed by a breath jam followed by an extraction of an easy spirit. It all happens in three to five seconds. In fact, the mouth - opening act allows for the release of endorphins, the well - being hormone. In some cases, tears may come out of your eyes as a tear gland stimulates.

So it's like a response to lower temperatures. That's weird.

Simply, the tendency to open our mouth when someone else has opened up is also reduced by lower temperatures. What happens to the brain when we talk?

When we open our mouth, our jaws lie down. This increases blood flow into the skull.

Like a huge wave of air filling your nostrils, that blood cools and is sent to your front brain. It's a simple thermo-organizing mechanism that activates when the brain needs a little rest.

The opening of the mouth can be contagious in nature so that it can refresh the brain of an entire group.

If your friend next to you is talking, you may need to be opened up too.
