Adrenaline rush or fear?

An interesting experiment was held. 45 people who did parachute jumping took part in the experiment. When people were jumping out from the plane, a special apparatus was put to their hand to investigate the structure of the blood.

During the first seconds of the flight the level of adrenaline rose in 6-7 times. The blood also got a lot of other substances and hormones that cause euphoria and pain killing effect.

So, scientists confirmed that when a person was afraid, the organism prepared for the danger and even got it ready for infections and injuries creating cell-killers to fight with diseases.

But sometimes people may have too much adrenaline. It is strange to read it as we got used that people feel the lack of it inventing new ways and methods to get the adrenaline rush.

Adrenaline doze may be very dangerous if a person suffers from some diseases or his/her health is generally very bad. It may be explained from medical point of view. The sudden increase of hormones in the organism gives intensive load to the heart and especially to cardiovascular system. That is why it is really possible to die from the fear.

During some catastrophes people die not because of injuries but because of fear. There are also cases when suicides who decided to jump out from the window, died before the contact with the ground.
