9 strange things that are the protective mechanisms of our body

Our body is a complex combination of numerous biological processes and systems, which, admittedly, we do not always understand. And a set of defense mechanisms is one of them. Our body protects us 24 hours a day, 7 days a week from everything that can harm us.

Here are 9 amazing things that our body does, and we don't even know for what reason.

When we eat too fast, swallowing huge chunks of food, or simply overeat, it can lead to irritation of the vagus nerve, which passes through the stomach and diaphragm. As a result, there is an attack of hiccups.

We yawn mainly to cool the brain when it is overloaded.

We usually sneeze when there are too many allergens, germs, dust and other irritants in the nasal passages. This is our body's way of getting rid of "garbage".

Unconsciously, we stretch to prepare the body for the upcoming physical activities that await it during the day. Stretching warms up muscles, restores blood circulation and improves our mood in the morning.

We mean that strange feeling when you just start to fall asleep, as there is a feeling of a sharp fall, we shudder and wake up. At this moment, all the muscles contract in a spasm so much that you can fall off the bed.

This phenomenon is the result of the fact that when we begin to fall asleep, our breathing rate drops sharply, the pulse decreases very slowly and the muscles are relaxed. Our brain perceives these actions as the approach of death and tries to save us by giving out a convulsion.

The fact that the skin on the fingertips begins to wrinkle is actually very important. The body is faced with an increased level of humidity and realizes that, most likely, the environment is slippery. Therefore, the skin on the fingers begins to take on such a look that it is easier to contact with a slippery surface.

It usually happens after the most unpleasant and traumatic episodes of our lives. Our brain is literally trying to erase from memory the terrible things that happened to us.

The main function of the resulting goosebumps is to reduce the amount of heat that our body loses through the pores of the skin. That is, the body does everything so that we can warm up faster.

In addition to the fact that tears serve as protection for the mucous membrane of the eye when foreign objects get there, they are also an instrument of emotional protection. Scientists believe that in stressful situations, our body creates a new powerful source of irritation to distract a person from the pain he is currently experiencing.
