Stress could be roughly described as the opposite of relaxation. This state is referred as the reaction of a human to external stimulus by a famous endocrinologist, Hans Selye in 1936. Stress signifies different things for different people, but generally, the feeling of not having control is always distressful. Stress evokes the fight-or-flight response, which releases hormones such as adrenaline and corticosterone. This leads to anxiety, increased anger, hostility, and mild to moderate depression.
