In his book Light: Medicine of the Future, Jacob Liberman, OD, PhD, documents ten benefits of ultraviolet A and ultraviolet B (UV-A and UV-B). The following points are a synopsis of his research.
- UV light activates the synthesis of vitamin D, which is a prerequisite for the absorption of calcium and other minerals from the diet.
In a controlled study, the group receiving UV absorbed 40 percent more calcium from their diet than their counterparts who received no UV. 8,9,10,11,12,13
- UV light lowers blood pressure.
One study reported that ultraviolet light dramatically lowered blood pressure after one treatment. The effect lasted five to six days.14
- UV light increases the efficiency of the heart.
In 18 of 20 people tested, cardiac output increased an average of 39 percent. In other words, their hearts became stronger and pumped more blood.15
- UV light improves electrocardiogram (EKG) readings and blood profiles of individuals with atherosclerosis (hardening of the arteries).16,17,18,19
- UV light reduces cholesterol.
In one experiment, 97 percent of the patients had almost a 13 percent decrease in serum cholesterol levels two hours after their first exposure. Within this group, 86 percent maintained this level 24 hours later.20
- UV light assists in weight loss.
This may be because the UV stimulates the thyroid gland, which increases metabolism and thus burns calories.21
- UV light is an effective treatment for psoriasis.
The National Psoriasis Foundation reports that 80 percent of people suffering from this condition improve when exposed to UV.22
- UV light is an effective treatment for many other diseases, including tuberculosis and asthma.23,24,25
- UV light increases the level of sex hormones.
One medical laboratory found that estrogen has a sharp peak of absorption in a portion of the UV-B range (290 manometers). This finding indicates that estrogen is most efficient when a woman is exposed to UV wavelengths.26
- UV light activates solitrol, an important hormone in the skin that works in conjunction with the pineal hormone melatonin.27
Solitrol, possibly a form of vitamin D3, influences the immune system as well as many of the body’s regulatory centers.
