"I would be curious to know your opinion on sauna benefits. Can sauna to some extent substitute the detox program?"
Using a sauna for a detox is better than doing nothing. Sweating helps to cleanse the lymph nodes, and it is the only thing that really does. Cleansing the lymph nodes is of particular importance for people who have used aluminum-containing antiperspirants for years, for they need to clean aluminum out of the lymph nodes that are located in the armpits. This aluminum is the most significant cause of breast cancers and hormonal problems in modern society. Sweating from exercise would be much more beneficial to your overall health than a sauna.
