...There are certain types of stress that are acutely good for us and can benefit our health, such as exercise. We sometimes hear that stress is “the spice of life” and a life free of stress would be filled with boredom and hardly worth living... We have, as a species, risen to the top of the food chain because of our superior predatory instincts and intelligence, but we are sensitive to our environment just the same. Our environment is filled with life threatening microbes, and the resurgence of diseases, which were once thought to have been eradicated. This, with the combination of the natural ageing process and the wearing down of our physical systems, affects all of our performance. Our environment today has contributed to the piling-on of stressors, which has placed an unnatural strain on our systems, a strain we are not designed to handle. I have chosen to focus on why understanding elevated cortisol levels and learning how to better regulate it increases performance and well-being. Some of the many performance factors that can be affected by cortisol include: body composition, anaerobic and aerobic respiratory exchange, other hormone activity, nutrition, dynamic resistance, caloric intake, and glycemic index ect. the stressor. This is called adaptation. If the stage of resistance is prolonged, or the response is excessive, hyperadaptosis can occur (the second stage). This is why it is important to increase one’s ability to cope with stress. The (third stage) of stress is exhaustion, involving a depletion of energy reserves and leading to fatigue, or other symptoms or diseases.
