Dr. Richard Weller has promoted sun exposure as a method of increasing nitric oxide (NO) in the vascular system, thereby lowering the risk of heart disease. NO is a potent vasodilator that lowers blood pressure, which according to the World Health Organization, is the leading cause of premature death and disease worldwide.1 But NO may have other beneficial effects.
There is also research showing that NO, which is also an oxidant, has the ability to retard or reverse tumor growth, making it a potential anti-cancer therapy. The problem with this of course, is that if it is used as an anticancer treatment, the oxidation has the potential to harm other systems of the body; After all, that is why we use antioxidants. However, the body beautifully controls the natural use of oxidants to specifically target tumors and leave healthy tissue untouched. As one group of researchers states: “…there is considerable controversy and confusion in understanding its role [NO) in cancer biology. It is said to have both tumoricidal as well as tumor promoting effects which depend on its timing, location, and concentration.
The best way to use NO, in my opinion, is to let nature take its course and use sun exposure to produce NO. Then, the body’s natural physical process will use oxidation to destroy tumors and simultaneously reduce the risk of cancer.
Safely enjoy the sun.
