'Don't sweat the small stuff.' It is a phrase that we've all heard before. But it turns out that this advice is worth paying attention to. When you worry about every little thing in your life, your stress levels spike enormously. It turns out that it doesn't matter what you are stressing about: being 5 minutes late to a meeting or anticipating major surgery. Your body doesn't know the difference. It responds to any type of stress in the same way: raised cortisol levels. If your cortisol levels are constantly high then your body reacts in the same way as if you were in a war zone. So learn mechanisms for keeping your stress levels at bay. Meditate, practice yoga, drink a warm mug of hot chocolate-whatever you need to do to keep your cortisol levels down. If you are having trouble managing your level of stress on your own, please contact a psychologist or other therapist. They can help you develop and maintain strategies for reducing your stress.
