Chronic stress means chronic cortisol release, something nature did not intend. People with Cushing's Syndrome get this seriously because they are producing too much cortisol. People under chronic stress get their own versions of the syndrome. One of the ways cortisol damages the body is by stopping the production of eicosanoids, essentially stopping cellular communication. The hippocampus senses the body's biochemical environment and adjusts hormones accordingly.
Excess cortisol destroys the body's control system.
Don't consume a lot of carbohydrates which raise insulin levels. Change your life and your outlook. Learn yoga, meditation or other stress control techniques. See the links page for the Tools For Exploration site where electronic brain machines can do it faster and more powerfully. Too much exercise or pumping iron for more than 45 minutes will stress the body and create a cortisol overload.
