The World Health Organization (WHO) says that exposure to the sun is
killing 60,000 people per year. Although the report mentions a
beneficial effect of Ultra Violet Radiation (UVR), primarily the
production of Vitamin D in the body, there are hazards from too much
sun.
Living closer to the equator and living at high altitudes can make you
more prone to UVR exposure. Water and snow can also reflect the
radiation, according to the report.
The WHO recommends limiting exposure to the sun by staying in shaded
areas, wearing hats and sunscreen. The largest “disease burden” for
North America, Europe, New Zealand and Australia is Melanoma. The
largest burden for Africa and most of Central America is cataract.
The WHO says that not all melanoma is attributed to sun damage, however
a sometimes pre-malignant condition called solar keratoses, or small
spot on the skin damaged by the sun, is 100 percent attributable to the
sun.
So how much sun exposure do you need for producing vitamin D? Well it
depends on who you talk to. The Mayo Clinic in Minnesota says just a
small amount of sun exposure is necessary for production of vitamin D.
The Mayo says “Ten to 15 minutes of sun exposure twice a week to the
face, arms, hands or back without sunscreen is usually enough.” They
add that the sun is not the only source of vitamin D. Eating foods such
as fortified milk and cereals, salmon, herring, eggs and mushrooms, can
also aid in the production.
