I have often heard the question “why do we roll to the right after savasana?” When I’ve asked the question I’ve received several answers.These are the theories Ive come across:
1. Rolling to the right side of the body is rolling away from the heart (less pressure and weight on the rested and open heart).
2. When rolling to the right the left nostril, which is the yin side remains more open thus balancing yin and yang after a yang practice (It should be noted: to activate the sinus reflex by rolling to one side or the other, you may need to stretch the lower arm out, over your head, and use it as a pillow)
3. The right side of the brain is more meditative. The left side is more active.
4. We roll to the right because the sympathetic (active response) nervous system is primarily associated with the right side of the body, and the parasympathetic (relaxation response) nervous system is primarily associated with the left. Rolling to the right activates the meridians on the sympathetic side, creating more wakefulness and linking back to the active world. Rolling to the left would activate the parasympathetic meridians and keep one just a bit too dreamy and sleepy, in theory.
There was also something I heard once about acidity in the stomach but it wasnt fully explained.
Another related point is that pregnant women are advised to roll and rest on their left side (for circulation reasons?)
I welcome any ideas or further theories!
