For those looking for a way to shed some stress. Try this yoga pose AKA the corpse pose. Think about it. You can't get much more relaxed than that.
Here is a variation called the "Body Scan." Similar idea to Savasana but with some specific breathing ideas included. Its highly recommended. Four stars. Two thumbs up.
The Body Scan from the book 'Full Catastrophe Living' by Jon Kabat-Zinn
"The Body-Scan...involves lying on your back and moving your mind through the different regions of your body. We start with the toes of the left foot and slowly move up the foot and leg, feeling the sensation as we go and directing the breath into and out from the various regions. From the pelvis, we go to the toes of the right foot and move up the right leg back to the pelvis. From there, we move up through the torso, through the low back and abdomen, the upper back and chest, and the shoulders. Then we go to the fingers of both hands and move up simultaneously in both arms, returning to the shoulders. Then we move through the neck and throat, and finally all the regions of the face, the back of the head and the top of the head. We wind up breathing through an imaginary "hole" in the very top of the head, as if we were a whale with a blowhole. We let our breathing move through the entire body from one end to the other, as if it were flowing in through the top of the head and out through the toes, and then in through the toes and out through the top of the head. " (note: please refer to the book "Full Catastrophe Living" by Jon Kabat-Zinn for complete instructions on this extremely useful, totally relaxing, and anxiety reducing technique. The book is published by Delta.)
