Our Human body is incredible and is designed to cope up with different environmental conditions. Our Human body has a special mechanism called Flight or Fight Response Mechanism which we all inherent with our living. However like two sides of a coin this flight and fight mechanism helps us in certain situations of danger and on the other side this damages the bio mechanism of human body. Hence this 'fight and flight response mechanism' is considered as 'Boon and Bane' as well.
Story about flight and fight mechanism:
For better understanding this i will tell a story which happened 10,000B.C. A caveman after his day long hunt came to his cave, he was tired and hungry as he could not able to get the food that day. Suddenly he say a deer in his cave lying. Then he has to kill it for his survival, during that situation 'Adrenaline' was secreted which results in blood supplied to brain reduced and supplied to legs and hands. Oxygen supplied to muscles and he become stiff, he fights for the food and certainly got that.
The other day he came back after hunting and couldn't find anything to eat. Suddenly he saw a Lion sleeping in his cave. After being in such situation same thing happened, Adrenaline pumped out his hands and legs become stiff but during this situation, he did not fight lion because he will be out ruled in front of the king of the jungle. So the adrenaline pumped during this period helped him to run much faster and save his life.
From the story it is understood that during high stress situation Adrenaline pumped out and saved the man in both the cases. Adrenaline pumped out is used as physical energy.
( Story is made just to make fun don't feel bad)
But the cave man days are gone now we are not living in life threatening situations every days. But during stressful situations for us adrenaline pumps out (office meetings, exam preparation, inspection day etc.). As mostly we are not involved with high physical workout. The pumped out adrenaline mix with blood and causes headaches, heart attacks, increase in blood pressure which results in ill effects.
