Write in a journal. Keep a journal in your briefcase or tote bag, and when you're upset or angry, take a few minutes to spew. This is a safe way to vent your emotions without alienating your co-workers.
Move around. A 15- to 30-minute walk will calm you, but if you're strapped for time, even a two-minute walk has been shown to reduce stress.
Create a workplace shrine. Make a corner of your desk a sacred space with a picture of a sunset, flowers, your family, sweetheart, a spiritual leader or whatever soothes your soul and brings you peace. When you're feeling anxious, go to your shrine. "Stop for just 10 seconds, look at the photo, then breathe in the feeling or vibration of the picture," suggests Fred L. Miller, author of the upcoming book How to Calm Down (Warner Books, 2003).
Breathe. Chase panic away with mini relaxations: Take a deep breath to the count of four, hold it for a count of four, and slowly release it to the count of four. Repeat several times.
Have a mantra. Create a soothing mantra to recite during a difficult situation. Take a few deep breaths and as you release them, tell yourself, "Let this go," or "Don't blow up."
If all else fails, go home "sick." Ask someone to cover for you, and head home. Snap in a soothing CD, jump under the covers and take a much-needed break from your job -- and the rest of the world.
