The Effects of Stress on Your Body
Stress is any change in the environment that requires your body to react and adjust in response. The body reacts to these changes with physical, mental, and emotional responses.
Stress is a normal part of life. Many events that happen to you and around you -- and many things that you do yourself -- put stress on your body. You can experience good or bad forms of stress from your environment, your body, and your thoughts.
