Abstract
A physical injury might be a part of sports, but can be
mitigated and even treated by using molecular hydrogen administrated from specially formulated sunscreen
lotion. In this regard, as a photocatalyst works like a
semiconductor, and can absorb a harmful UV band from sunlight, a hydrogen-producing photocatalyst
can be doped in a hydrogel to administrate hydrogen and protect UV rays as sunscreen together. The job of the hydrogel, in this case, would be to absorb sweat to give water to the catalyst, which would then produce hydrogen and act as a topical gel. Using such modern materials, athletes with specific wound-prone muscles or nerves can be returned to their natural state. Because hydrogen may disperse across the body, it can aid in the treatment of a variety of disorders. Most importantly, as the hydrogen also cures wounds, inflammation or wrinkles on the skin, the photocatalyst containing hydrogel will also be very effective in treating skin damages, besides protecting the sunlight.
