The benefits of sunlight are astounding. An old proverb quotes " Waterbathing is good; full skin airbathing is better ( I think it was Roosevelt who was keen to take an air bath in the early morning every morning); but sunbathing is the best".
This is just repeating what I have said from the very beginning of my association with curezone; the elements of robust health come from what nature has provided; sunlight, pure water, pure unadulterated raw food, physiological(fasting) and physical rest & sleep, exercise and emotional poise. This is ALL anyone needs for optimum health, namely; Natural Hygiene. As described and endorsed by Shelton; Tilden; Page; Oswald; Jennings; Trall etc.
In fact Natural Hygiene saved my life: in 1976 under the care of a Natural Hygienist: Dr Keki Sidhwa, where I fasted under his care for 26 days on pure water only for a mixture of lifelong health problems. Result? A degree of health unheard of in humans.
