Indian-Canadian actress Lisa Ray, who calls herself a cancer graduate, swears by the prowess of yoga and feels "Watsu" is the most relaxing therapy.

"'Watsu' is the most relaxing water therapy I've experienced: a visit back to the womb," Lisa posted on her Twitter page.

"Watsu" is a form of therapeutic bodywork performed in warm water pools, where the receiver of the treatment is supported by the practitioner, creating a sensation of floating.
