In terms of physical exercises, I think that any form of exercise is beneficial to lowering stress! Whether it be anything as simple as taking a walk everyday to calm your nerves, give you some peaceful, quiet time for yourself just to relax or something more vigorous as running [a personal favorite of mine :)], I personally feel that anything that keeps your body active and moving will help clear your mind and relieve pressures of stress. Especially if you are speaking medically to stress in terms of high-blood pressure, I believe there is a correlation to how exercise can lower your blood pressure, often caused by stress: "Exercise. Exercise is one of the best ways of distracting yourself from your stress triggers. It can help clear your mind and work off anger and frustration. Also, exercise has many other great benefits, such as: * Lowering your blood pressure. * Contributing to weight loss. * Improving your cardiovascular health. Try deep breathing, meditation, or yoga. These techniques can help quiet your mind and counteract your body's physical stress reactions. You can check local fitness centers and community centers for classes or instructors."
