The secret of a single part of the body never

Goose bumps are normal when we are cold, or scared . but there is a magic part that is immune to goosebumps, you know?

Whenever cold, scared or urinated . many people often shiver, goosebumps. But do you know that there is a "immune" part of this body in our body?

Whenever cold, many people often shiver, goosebumps.

And the answer is the face area . But why is that?

When we are cold or have intense emotions, the sympathetic part of the autonomic nervous system will be strongly stimulated. The task of the autonomic nervous system is to maintain the physiological balance of the body.

The phenomenon of goosebumps that we often see.

Meanwhile, the sympathetic system regulates visceral activity in accordance with normal physiological state, resting.

When this system is active, it will stimulate the production of adrenaline hormone - causing small muscles to connect to the subcutaneous hair follicles on the body.

At the same time, they will make the skin surface around the hair shrink more tightly, the skin surface will fall slightly. Obviously, the hair and legs are more clearly visible at this time. That is the phenomenon of goosebumps.

These hair follicles are everywhere in our bodies.

These hair follicles are everywhere in our bodies. However, there are some parts we will not be able to observe the phenomenon of goosebumps occurring - typically the face.

The reason is because the distance between the hairs on the face is very small. When the hair-raising muscle shrinks, the skin also pulls down, but because the area of ​​the skin between the feathers is not large, the phenomenon of goose bumps is not as obvious as in the arms and legs.

In addition, there is another explanation for this phenomenon. In body parts such as hands, feet or face, the muscles under the skin have many more important tasks - such as the subcutaneous muscle on the palm is also responsible for supporting the grip.

We should feel lucky when our bodies are miraculously constructed.

Similarly, the expression of facial expressions "mobilizes" the support of many muscles under the skin.

These expressive muscles thrive, "overwhelming" the activity of the hair-building muscle. As a result, we can hardly recognize the presence of "chicken skin" on our faces.

We should feel lucky when our bodies are miraculously constructed. Because maybe you can't imagine how poorly I will look when bumps float on my face.
