Is it possible to die of fear?

Fear is a normal reaction of the body to what is happening around. There are cases when you can die from fear.

At the moment of fright, the body “signals” that it is necessary to either run away or fight. This has long been considered survival.

At the moment of fright, the heartbeat begins to increase, blood flow increases, and the pupils dilate. When a person is frightened, his body produces a large amount of energy in order to develop a record speed for him or to fight back against the enemy.

The instinct to fight back against the enemy appears. If a person does not have such an instinct, then his body gets sick, because when we are scared, adrenaline is released. It creates a load on the heart.

Adrenaline produces a chemical that penetrates the heart in the form of calcium ions. They make the heart beat faster. If the amount of adrenaline is too high, fibrillation begins (an abnormally fast heartbeat, similar to trembling).

It occurs in the lower chambers of the heart, the ventricles, preventing them from pumping blood. If the heart rhythm does not normalize, a person can die.

The release of adrenaline is dangerous both during stressful situations and during joyful events in a person's life, because these emotions can lead to fibrillation. Moreover, the release of adrenaline can damage the lungs, liver, and kidneys.
