Poor cortisol: It means well but just doesn't know when to quit. Produced by your adrenal glands, this "stress hormone" helps regulate blood pressure and the immune system during a sudden crisis, whether a physical attack or an emotional setback. This helps you to tap into your energy reserves and increases your ability to fight off infection.
Trouble is, relentless stress can keep this survival mechanism churning in high gear, subverting the hormone's good intentions. Chronically high cortisol levels can cause sleep problems, a depressed immune response, blood sugar abnormalities, and even abdominal weight gain. "When cortisol spikes, it tells the body to eat something with a lot of calories—a great survival tactic if you need energy to flee a predator but not if you're fretting over how to pay bills," says nutritional biochemist Shawn Talbott, PhD, author of The Cortisol Connection.
