Stress management in your busy, active life plays an important role in keeping your body healthy. Although stress can't be avoided, it can be controlled. When stress is repeated, excessive and left untreated, your body can develop physical health problems, such as high blood pressure, weakened immune system, and mental issues like depression and lack of concentration. Strategies like exercise, yoga, meditation or participating in stress-reduction programs are effective ways to manage your stress and help keep your body healthy.
