Does Sunlight Danger Outweigh the Benefits?
Many studies demonstrate that exposure to sunlight provides protection to diseases such as hypertension, diabetes, multiple sclerosis, and a variety of cancers, and avoiding sunlight may influence their progression.[1. Razzaque MS. (2018). Sunlight exposure: Do health benefits outweigh harm? J Steroid Biochem Mol Biol. Jan;175:44-48.] It has been thought that these protections are due only to vitamin D, whose creation requires sunlight, but researchers are now reporting that circadian clock influencing, immune response modification, and nitric oxide, melatonin, and serotonin formation are involved as well.[2. Van der Rhee HJ, de Vries E, Coebergh JW. (2016). Regular sun exposure benefits health. Med Hypotheses. Dec;97:34-37.] In fact, researchers are finding that the risk of skin cancer increases with irregular patterns of sun exposure, while regular patterns convey relatively lower risk. This is the difference between getting sunburned versus a brisk daily walk in the sunlight.
But too much sunlight is harmful to both eyes and skin. We know that getting sunburned increases skin cancer risk. Our vision is also directly negatively impacted by the sun and ultraviolet radiation (UVR), as well as blue light from computer screens. Continue reading “The Sun and Your Eyes: Enemy or Friend?”

Vitamin D
There is no cure for the degenerative brain disease called Alzheimer’s, and current conventional treatments have a limited effect. However, research into a drug used to treat skin cancer may show “stunning” potential to help with Alzheimer’s disease.
