“Weller states that all-cause mortality is much higher in the winter than in the summer months. For example, a person living in Scotland is 30% more likely to die during a week in January than in July. However, the same risk does not occur in countries near the equator with substantial year-round sunlight exposure. Weller is not the only person who has reported dermatologist’s sun-phobic recommendations. A 2020 article in the International Journal of Environmental Research and Public Health states: “Studies in the past decade indicate that insufficient sun exposure may be responsible for 340,000 deaths in the United States and 480,000 deaths in Europe per year, and an increased incidence of breast cancer, colorectal cancer, hypertension, cardiovascular disease, metabolic syndrome, multiple sclerosis, Alzheimer’s disease, autism, asthma, type 1 diabetes and myopia.” The same authors note the benefits of ultraviolet B exposure from the sun that go beyond vitamin D, such as the direct benefit of genes for immunity.” — Dr. Mark Stengler, NMD, MS
