Stress is any interference that disturbs a person’s healthy mental and physical well-being or any influence that disturbs the natural equilibrium of the body or mind. Stress is the physiological response of the body to threat or danger or sudden stress. The body prepares itself for sudden action, either to run away or stay and fight. This is called the fight or flightresponse. It can affect the body in a number of ways, including a raised heart rate/pulse rate, surface of the blood vessels constrict, body hairs stand on end, increased blood flow to the muscles, blood pressure rises, breathing becomes faster and deeper to provide more oxygen, mouth becomes dry and muscles tense up to prepare for action. The structures in the body that are mainly responsible in triggering this response are the hypothalamus, pituitary and adrenals.
