Recent studies are actually encouraging Americans to seek out sun exposure in an effort to boost vitamin D levels, since, according to 'The National Health and Nutrition Examination Survey', 41.6 percent of us are deficient. But getting more sun could become problematic considering another new study found that only 14 percent of men and 30 percent of women regularly protect their skin from cancer-causing rays. With melanoma, the most serious form of preventable skin cancer—causing more than 9000 deaths per year in the US alone—the medical community is desperate to spread prevention awareness. How do you find the balance between getting vitamin D and protecting your skin? Do you wear sunscreen? If not, why not? Let us know in the comments (oh, and share your favorite SPF product picks).
