SUNLIGHT ROBBERY:
Health benefits of sunlight are denied by current public health policy in the UK

Health Freedom Alliance » Vitamin D Fears Lead to Sun Warnings Review.

“Warning people to stay out of the sun may have led to vitamin D deficiencies, British newspaper The Independent reported Monday.
The newspaper cited a confidential report from Cancer Research U.K., which revealed the charity was reconsidering its advice about avoiding the sun between 11:00 am and 3:00 pm. The charity was responding to concerns that people were at risk of a lack of vitamin D without adequate exposure to sunlight. Medical researcher Oliver Gillie told the newspaper the current warnings to stay out of the sun may be causing health problems.

“Lack of sunshine and the vitamin it makes in our skin is probably the most serious single cause of disease in the U.K. today. Vitamin D deficiency is well known as the classic cause of rickets and serious bone diseases,” he said.”

Study Explores Link Between Sunlight, Multiple Sclerosis.

Newswise — For more than 30 years, scientists have known that multiple sclerosis (MS) is much more common in higher latitudes than in the tropics. Because sunlight is more abundant near the equator, many researchers have wondered if the high levels of vitamin D engendered by sunlight could explain this unusual pattern of prevalence.
