Humans adapted to life under the sun over millions of years, but modern western medical advise is to avoid the sun’s UV radiation by wearing sunglasses and applying sunscreen. These “healthy” guidelines became popular in the 1940’s.
- Some studies have cited data that the incidence of skin cancer is higher among populations that live further from the equator and that people who work outside actually have lower rates of melanoma. We get less sun exposure then at any time in history, yet skin cancer rates are increasing.
- Sunscreen ointments are not proven to reduce skin cancer; they are only proven to reduce sunburn. Some studies suggest that sunscreen may actually be a cause of skin cancer by creating vitamin D deficiencies. Vitamin D deficiencies are at epidemic levels. Low levels of vitamin D is also common in many chronic modern diseases, including Alzheimer’s.
- Sunglasses do more than block the UV spectrum; they also filter portions of the visible spectrum, depending on the color of the lens. We create artificial light by wearing sunglasses. Also note that UV protection ratings of sunglasses is not enforced or tested; we are trusting that the manufacturer label is true. Dark colored sunglasses cause the pupil to remain unnaturally open. If these dark lenses do not block UV radiation as claimed by the manufacturer one would be allowing more UV light into their eyes!
- I stopped wearing sunglasses and the sun no longer appears too bright. There are rare times when sunglasses with UV radiation protection may make sense, such as on a bright beach or in bright snow or for pilots flying in airplanes at abnormally high altitudes, but they are not required for most situations.
Happy 4th of July…fear not God’s only Sun!
