Here's a quick, pleasant way to release stress.  This exercise can be easily practiced at home or at work to maintain your health and relieve stress.  (1) Sit forward on the front edge of a straight-backed chair. (2) Briskly rub your lower back using a light touch by placing the backs of your hands against your lower back along both sides of the spine and rub up and down for one minute, creating warmth from the friction.  (3) Hold the base of the skull with one hand and place the middle and ring fingers of your other hand approximately one inch above and between the eyebrows.  Tilt your head back, close your eyes and breathe deeply taking three long, slow, breaths.  Imagine each deep breath brings a healing substance that penetrates and dissolves your pain or tension.  Hold each breath for a couple of seconds at the top of the inhalation.  Exhale while smoothly letting go of your tension.  Continue breathing deeply for one more minute while visualizing each breath carrying healing energy into your body.  (4) Sit back comfortably in your chair with your spine straight and your shoulders relaxed.  Press your fingers into your lower abdomen three fingers width below your navel.  Close your eyes, press firmly into this point and breathe deeply for one minute.  Source: Acupressure's Potent Points by Michael Reed Gach.
