If you need a bit of calming down during the day, here's an easy exercise to get you  back on track....This routine takes only five minutes and is helpful whenever you feel yourself worrying.
(1) Place your fingertips on the back of your ears, then slide them up to the top of your head in the center.  This point is at the indentation on the skull (the soft spot on a baby).  With the middle finger of the other hand press between the upper lip and the nose.  Straighten your spine and take long, slow, deep breaths for one minute.
(2) Place both hands on the upper outer chest region.  Breathe deeply into these points, breathing out any worrisome thoughts for two minutes.  Make the sound of ahhh on the exhalation to release tension and stress.
(3) Briskly rub both legs with your knuckles, four finger-widths below the kneecap, one finger-width outside the shinbone.  Rub for two minutes.  Doing this several times a day not only relieves stress but also increases your energy.
(4) If you have time, walk briskly, breathing deeply as you swing your arms vigorously for a few minutes.  Source: Acupressure for Emotional Healing by Michael Reed Gach, PhD and Beth Ann Henning, Dipl. A. B. T.
