THE SUN IS SHINING... AND IT WILL HELP YOU BEAT CANCER
Exposure to sunlight has also been linked to a reduced risk of multiple sclerosis and diabetes.
SCIENTISTS have also linked a lack of sunlight to 15 types of cancer.
In a series of ground-breaking studies experts have found evidence that sun exposure may protect against some forms of the disease, despite increasing the risk of skin cancer.
One recent study, published in the journal Anticancer Research, assessed cancer cases in 100 countries along with rates of ambient ultraviolet radiation.
More sunlight was "consistently" associated with reduced rates of many types of cancer including breast, cervical, colon, oesophageal, gastric, lung and two forms of lymphoma.
In a second study, published in the journal Cancer Causes & Control, death rates and cancer cases were analysed in 263 Chinese counties alongside satellite measurements of sunlight.
It found death rates for all cancers were reduced in areas where there was more sunlight. It also found incidence that some cancer types had the same correlation with ultraviolet light.
Professor Ann Webb, a specialist on ultraviolet light at the University of Manchester said that
researchers suggested that vitamin D, produced by sunlight on the skin, "may reduce the incidence or improve the outcome of cancer".
A third study, published this month in the International Journal of Cancer, involved nearly 451,000 people in America. Scientists found exposure to ultraviolet light was linked to a reduced risk of various cancers including prostate, kidney, colon and bladder. This research also accounted for other risk factors including diet, exercise and smoking habits.
Experts suspect the role that sunlight has to play in producing vitamin D may explain the findings. Professor Ann Webb, a specialist on ultraviolet light at the University of Manchester, said.
