9.4 Concluding Remarks
The aging of the populations in the industrial world means that we are living much longer with the consequences of sun exposure. The first approaches of screening or filtering the solar rays are chemically and physically effective but ran into resistance from human behaviour. A better understanding of the biochemistry led to the use of a variety of antioxidants which quench or intercept oxygen radicals and ameliorate some of the effects of solar UV. We now have available DNA repair enzymes to actually reverse or repair damage after it happens but before it can have its effects. We should be careful to use these tools properly, so that we do not facilitate greater overall exposure to some or all of the solar spectrum in the mistaken belief that protection is perfect. But in societies where the burden of medical care is becoming overwhelming, we should remember that prevention is preferable, both economically and socially, to treatment.
