Your muscles are very tense. Now you start worrying about your inability to sleep or about you body aches and pains. This creates more stress. See how this is triggering a domino effect. If you don't do something about it soon enough you can die.
Stress can also originate from emotional and psychological causes.
Then they worry about not getting enough sleep and how they will go to work without sleep. And so on. One stressful event leads to another and, if we don't control it, the domino effect kicks in. Even joyous events, such as a wedding, a job promotion, buying a new home, or the birth of a child, can cause much stress. You also might get stressed out if you cannot achieve a particular goal or satisfy a certain wish.
