is a natural feeling that is created in the mind, and is the way the body responds to a particular threat. Stress triggers physiological, emotional and chemical reactions in the body through a complex signaling pathway between neurons and body cells.
Stress alters the neurochemical composition of the body. The hypothalamic, pituitary, adrenal (HPA) axis is a part of the central nervous system
that also has endocrine functions and plays a major role in stress response system. It controls the secretion of hormones like epinephrine and cortisol, which help the person to cope with the stress.
Body systems like cardiovascular system, immune system, respiratory system, digestive system, sensory organs and brain witness changes in the presence of these hormones in order to ‘fight or flight’
the perceived threat.
Events that stimulate stress are called stressors. Stressors can be environment conditions, biological or chemical agents, stress causing events, work place problems, changes in life, etc.
There are two types of stress - Eustress and Distress. Eustress is short-term, exciting and is motivational. Distress is considered being beyond the coping capabilities and causes anxiety, concern, reduced performance and can last for a short or a long period of time.
Up to a certain point, stress isn’t bad, as it is just the body’s normal mechanism to stand up to the challenges, and helps in keeping motivation and morale high. But, beyond a point, it negatively impacts the quality of life.
