Stress serves an important role in our lives. It propels us to jump out of the way of speeding cars, finish papers by their deadlines, and push ourselves to excel in sports. However, when stress becomes a chronic occurrence, it can wreak havoc on our physical, mental and emotional health. Long term stress resulting in chronic over activation of the hypothalamic-pituitary-adrenal (HPA) axis can lead to mood disorders such as anxiety, depression, mood swings and irritability. Long term exposure to elevated stress hormones contributes to a host of other heath conditions such as diabetes, heart disease, irritable bowel disease and auto-immune disorders such as rheumatoid arthritis, lupus, chronic fatigue and fibromyalgia.
