The way that your body responds to stress is actually killing you over time. It is a thing that everyone has. When you are in danger, your body sends a signal to your brain saying to not touch that knife, not to fall off that cliff.
Yes, pain and stress can cause impatience. Stress is the body's response to a real or percieved danger, and one of the responses is anxiety, and that is a lot like impatience.
Sympathetic nerves: prepare the body for emergencies and stress by increasing the breathing rate, heart rate, and blood flow to muscles. These nerves become aroused as part of the fight-or-flight response, which is the body's natural reaction to real or imaginary danger.
Adrenaline is released by the adrenal glands in response to stress, excitement, or danger. It increases heart rate, boosts energy levels, and prepares the body for a "fight or flight" response.
Your Brain
Stress
The adrenal glands release adrenaline, the hormone most often associated with the fight or flight response and danger.
The neurotransmitter that helps the body return to normal after a stress response is the noradrenaline. It is also used to raise blood pressure.
Stress response
With chronic or severe stress, the body reacts by mounting a stress response through the stimulation of the sympathetic nervous system. This is also called the "fight or flight" response as the body arms itself to face what it perceives as danger causeing the adrenal cortex to increase production of the anti-stress hormone cortisol. Antidepressants calm the 'fight or flight' reaction of high cortisol levels.
Stress and anxiety are often used interchangeably but there are differences between the two. Stress is a response to an event that causes physiological stress in the body, while anxiety is a response to an event that causes psychological stress.
The stress response is basically the body's way of preparing to defend against some kind of external danger. The chemistry of the body changes to prepare it for action, like increased heart rate, increased respiration. If a person experiences stress, as in harmful stress, it doesn't know what to do with the excess energy. So exercise helps to burn it off so it doesn't have negative effects on the body.
