Your blood sugar rises. Most people think of stressors, or things that cause stress, as negative, such as traffic, a difficult job or divorce. Many people are aware of tense muscles, headaches or stomach aches during, before or after such situations. But stressors can also be positive experiences. Having a baby, bowling a perfect 300 game or completing a satisfying project are all changes that can activate your stress response.
Many people think of stress as another way of saying tension or pressure.
Actually, stress is just the way we respond to change. Your body can't tell the difference between a positive or negative stressor. In either case, your body experiences the same stress effects. If you are not able to let off steam and relax, these effects can be harmful. You may feel tired, depressed, or anxious.
