A Vitamin D theory that might not wash with you……………….There is a theory gaining support among some doctors and researchers that we are literally washing Vitamin D – which we get from the sun – down the drain!!
Consider for a moment how sunlight converts to Vitamin D in the first place — on the skin! You see, Vitamin D3 is actually not a vitamin at all. It is an oil-soluble steroid hormone. When your skin is exposed to ultraviolet rays, it converts a form of cholesterol into Vitamin D3 — but not instantly. It takes some time to make its way through the skin and into the bloodstream. How much time is hard to say for sure. Possibly it’s just a couple of hours; or it could be as long as 48 hours. Science is still researching that.
Perhaps after outside sun exposure we should just rinse our body and not use excessive soap applications until later.
The truth is that until the advent of indoor plumbing and hot water heaters, humans never showered as often as we do now. For most of us, that is at least once a day, and as many as twice a day or more when we go to the gym or the beach or pool.
