The opposite is the case: precisely because the sun is such a pleasant, seemingly completely harmless companion here, you have to be even more careful to apply sunscreen regularly. Even in the North Sea, our central star sends ultraviolet UVA and UVB rays that penetrate deep under the epidermis without us noticing. They can destroy collagen fibers and elastin, which are responsible for the skin's suppleness and elasticity.
Such warnings should not only be addressed to sun worshippers who spend many hours a day on their beach loungers. A particularly vulnerable group are water sports enthusiasts who, in their activity in the cool water, often do not even notice that they have already suffered sunburn.
