October 11, 2012 - Tanning beds have long been linked to skin cancer, and now researchers say the earlier people use them, the greater their risk. Researchers at the University of California, San Francisco analyzed tanning bed and cancer studies going back to 1977. They found people younger than 25 who used tanning salons had a significantly higher risk of developing non-melanoma skin cancer than someone who never tanned indoors. At least 170,000 cases of skin cancer each year are linked to indoor tanning, according to an analysis published online in the British medical journal.
Also, as cold season gets underway, researchers say, don't turn to vitamin D for relief. New Zealand scientists say it doesn't help fight colds. They followed 322 adults for more than a year and found no difference between the group that took vitamin D and those who didn't. The study is published in the Journal of the American Medical Association.
