Natural Hygiene does not substitute foods, fasting, sunbathing, etc., for drugs, but it uses these influences because they are essentials of health. Hygienic Self-Health Care peddles no cures and recognizes none. Instead, only nature, meaning those normal influences and processes of life, restore health.
Hygienic Self-Health Care cannot be reduced to a series of rules and regulations that involve absolute terms like “always” or “never.” Each day, however, all of us have to make decisions about how we will live in such a a way that we remain comfortable and relaxed with our lifestyle – and not uptight or fanatical.
