PHILADELPHIA (CBS) - A new report in the dermatology edition of The Journal of the American Medical Association suggests that Americans should buy umbrellas – but not for the rain!
Umbrellas can fight skin cancer by blocking UV rays.
A study from Emory University measured the ultraviolet radiation under 22 different rain umbrellas and found that they block an average of 77% of UV rays.
The hope is that Americans might consider them an extra layer of protection.
