Cutting  down  on  your  responsibilities  is  one  way  to  minimize  stress  in  your  life.  You  can  also relax yourself by breathing deeply, rather than taking light, shallow breaths. Peaceful music is also soothing if you focus your attention on it and consciously disregard distracting thoughts. Another good way to release tension is to exercise regularly, which, rather than tiring you out, builds energy and endurance.
