The depth of publicity to damaging ultraviolet (UV) rays “is better below h2o than it is previously mentioned h2o,” mentioned Dr. Arun Mavanur. He is a surgical oncologist at the Alvin & Lois Lapidus Most cancers Institute at LifeBridge Health, in Baltimore.

“UV rays also are mirrored off the area of the h2o, so all round you are inclined to get far more publicity even though you happen to be in the h2o,” he additional.
