What's Happening?
Dr. Adam Friedman, a professor and chair of dermatology at GW School of Medicine and Health Sciences, has emphasized the risks associated with UVA rays, which can penetrate windows and affect skin health even indoors. Unlike UVB rays, which cause sunburn, UVA rays are linked to accelerated skin aging and skin cancer. Friedman advises using sunscreen with SPF 30 or higher to protect against UVB rays, but notes that SPF does not account for UVA radiation. This revelation underscores the importance of comprehensive sun protection strategies, including awareness of indoor exposure.
Why It's Important?
The prevalence of skin cancer in the United States highlights the need for effective sun protection measures. Many individuals are unaware of the full spectrum of UV radiation and its effects, particularly the silent threat posed by UVA rays indoors. This information is crucial for public health, as it can lead to better skin protection practices and potentially reduce skin cancer rates. Dermatologists and health professionals may need to educate the public on the importance of protecting against both UVA and UVB rays, even when indoors.
