Dr. Reinhold Vieth, a leading researcher in the field of vitamin D, recently provided much needed clarity on the mass confusion and fear revolving around sun exposure.
Dr. Vieth reviewed a study conducted by Dr. Lindqvist and colleagues that began in 1990, observing the sun-exposure and lifestyle habits of nearly 30,000 Swedish women over a span of 20 years. The researchers aimed to determine if a relationship exists between sun exposure and multiple melanoma.
Surprisingly, the researchers observed no differences in all cause mortality or cutaneous malignant melanoma (MM) mortality between those who exposed themselves to the sun and those who avoided the sun. Additionally, those who avoided the sun experienced a shorter life expectancy (0.6 – 2.1 years shorter life expectancy) as they were at a higher risk of death from heart disease and stroke, diabetes, multiple sclerosis and pulmonary disease. When comparing smokers who sun bathed to non-smokers who avoided the sun, the researchers found that the women had an equal risk of mortality.
The researchers concluded,
Avoiding sun increased risk of dying by the same amount as smoking did.
