Working outdoors linked to lower risk of breast cancer among older women
Outdoor workers are able to make more vitamin D which may be protective, say researchers.
Working outdoors over many years is linked to a lower risk of breast cancer in women after the age of 50, finds research published online in the journal Occupational & Environmental Medicine.
Outdoor workers are exposed to more sunlight, boosting their levels of vitamin D, which may protect against the disease, say the researchers.
Vitamin D has a well recognised role in maintaining bone and musculoskeletal health, but it may have other roles, including helping to ward off infection and cancer.
The primary source of vitamin D is UVB sunlight. However, concerns about skin cancer risk and the increasing use of computers for both work and leisure have decreased the amount of time people spend outdoors.
