Physiological and psychological effects of prolonged or intense arousal
Stress is the process of adjusting to/or dealing with circumstances that disrupt, or threaten to disrupt, a person's physical or psychological functioning. Stress involves a relationship between people and their environments, more specifically, between stressors and stress reactions. Stressors are events and situations, such as an exam, to which people must react. Stressors can be both physical (or environmental) and psychological (or mental).
Stress weakens the effectiveness of the body's immune system, its natural defence system. The person is then more vulnerable to harmful cells in the body and becomes ill. Stress reactions are the physical, psychological and behavioural responses people display in the face of stressors.
