Stress is an automatic physical reaction to a danger or demand. Muscles tighten, blood pressure rises, the heart speeds up, extra adrenaline rushes through your system.
Everyone feels the effects of stress. Stress is a fact of life. Some stress can be good for you, because it inspires you to better meet life's challenges. It's the "fuel" that powers you over life's obstacles...from job interviews to personal tragedy. But too much stress can harm your physical and mental well-being. That's why you need to be able to control stress...so that it doesn't control you.
