Stress is a feeling that we created to react to certain events . It is the way in which the body is faced with a challenge and is prepared to act in a difficult situation with focus , strength , stamina and mental acuity.
The events that provoke stress cover a variety of situations - from being in physical danger to making a class presentation or taking a semester with the most difficult subject.
The human body responds to these situations by activating the nervous system and certain hormones. The hypothalamus sends signals to the adrenal glands to produce more adrenaline and cortisol and send these hormones into the bloodstream. These hormones increase heart rate , breathing rate , blood pressure and metabolism. The blood vessels widen to allow more blood flow to the muscles , putting them on alert. Pupils dilate to improve vision . The liver releases stored glucose from increasing the body's energy . And the body produces sweat to cool off. All of these physical changes prepare a person to react quickly and effectively when you feel emotional stress.
