Last night my stress releasor was my 3 year old son.  He fell asleep in the car on the way home from daycare.  Instead of waking him up when I got home, I carried him into the house and sat in the rocking chair with him asleep in my lap.  We must have sat like that for 30 or more minutes.  After that, I was totally calm.

Other de-stressors:
- blowing bubbles with my kids in the backyard.  It might be the fact that you are taking deep breaths but it is very relaxing.
- long, long bath - sometimes with just candles for lighting and soft music
- hot cocoa and a good book.  I am currently reading Sense and Sensibility.
- and for immediate stress relief from "stupid" people, using my thumb and forefinger to squish people's heads (like Kids in the Hall)
