One part of the 21-day cleanse that I didn't use (because I didn't have access at the time) was a sauna. IIRC, the rationale behind using a sauna is to allow toxins to escape your body through your open pores. Don't know how effective it is, because I've never used it in the context of a cleanse. Sounds like something cool to try, though. No time soon, though. I belong to two gyms and neither one has a sauna. *shrug* I tried a different cleanse (can't remember the name of it) that used hydrotherapy -- in this case, taking showers that alternate between ice cold and steaming hot, with some self-applied massage. I can't remember what that was supposed to do for you (something to do with the lymphatic system, IIRC) but I'll tell you what. It felt freaking awesome. Shower then lie down and be still. Very ... tranquil. A great time to meditate.
