What is stress?
If you think stress is something that makes you worry, you have the wrong idea of stress. Stress is many different things: happy things, sad things, allergic things, physical things. Many people carry enormous stress loads and they don't realize it!
We are all familiar with the word "stress". Stress is when you are worried about losing your job, or worried about having enough money to pay your bills, or worried about your mother when the doctor says she may need surgery. In fact, to most of us, stress is synonymous with worry. If it is something that makes you worry, then it is stress.
Your body; however, has a much broader definition of stress. To your body, stress is synonymous with change. Anything that causes a change in your life, causes stress. It doesn't matter if it is a "good " change, or a "bad" change, it is stress.
