UV Rays Prevent the Spread of Chickenpox

Exposure to ultraviolet rays (UV rays) can help stop the spread of chickenpox, according to researchers from the University of London.

Scientists found that the illness is less common in regions with high UV levels. Exposure to sunlight may inactivate viruses on the skin like the varicella-zoster virus, responsible for chickenpox and shingles, making it harder to spread.
