While summer has almost arrived, sunscreen is something that people should start thinking about. According to a new study from the JAMA (Journal of the American Medical Association), during hot summers is vital for everyone to use sunscreen even before they leave the house just to get into the car, regardless of the activities they have in that day.
Two types of UV light are known, which can damage your skin, UVB and UVA. UVB rays are capable of burning your skin whereas UVA ones can age your skin prematurely, leading to age spots and wrinkles on your body parts, according to Mayo Clinic. However, both of them can cause skin cancer after staying too much in the sun.
For the research, 29 different cars made by 15 different manufacturers were tested to determine how many of the UVA rays passed through side windows and windshields. One of the experts, Dr. Archelle Georgiou and KSTP’s Leah McLean explained the efficiency of side and front windows against UVA and UVB and which one of the windows assure a better protection.
The most deadly type of skin cancer is melanoma. It is a fact that this disease has doubled during the last 30 years, but recently, scientists made a breakthrough.
They learned that the correct use of sunscreen reduces the risk of skin cancer up to 80 percent. It seems that no one knew until now that sunscreen is very efficient even against melanoma. According to the scientists from Ohio State University, many types of SPF 30 sunscreens have been used on mice which were exposed to UVB light. They chose mice because their skin is genetically similar to humans.
Furthermore, the results were spectacular. Every type of SPF 30 sunscreen reduced the risk of melanoma by an impressive 80 percent. According to the lead researcher, Christian Burd, is excellent that their work paid off, and now, melanoma can be prevented significantly. Moreover, he thinks that they can still develop better sunscreens with a higher percentage of protection.
Still, the experiment is not ideal. Besides the fact that it was successful on animals, only UVB light were used and not the entire range of UV emitted by the sun, meaning that the mice were exposed to a lower lever of UVB, associated with a week’s time spent in the sun.
All the information was just presented at the American Association for Cancer Research Annual Meeting, and everyone hopes that very soon a better, more efficient sunscreen will be developed.
