The stress response is a natural defense mechanism. In an emergency situation, the body switches to a mode where the priority is to mobilize all forces in order to survive a crisis situation.
The reaction to stress takes place in three successive stages.
Stage of mobilization
At this stage, the body is preparing to solve the problem. This is accompanied by the following reactions: increased secretion of hormones, increased heart rate, deepening and acceleration of breath, increased muscle tension, increased blood pressure, decreased sensitivity to pain, accelerate metabolism, increase endurance and physical strength. They can appear violent emotions: fear, anger. Often there are difficulties in concentrating and loss of contact with the environment. There are also such reactions as, impatience, coercion action, aggression.
Stage of activity
In this phase, we are struggling with the solution of the problem. Accumulated energy is consumed for action.
Stage of exhaustion
This is the last stage of stress. After running out of the accumulated energy, it is necessary to rest and regeneration. If the issue is resolved and you have time to rest, then after a short time you will be able to return to normal activity. In the opposite situation, it can lead to chronic stress. Constant tension, physical and mental exhaustion is very detrimental to health.
