Beach Sun-bathing
Those who have access to a beach may take part of their sun-baths there. Here it will be necessary to wear the bathing-suit, which is usually made of materials and of colors that prevent practically all the actinic rays from reaching the covered parts of the body. But sun-baths so taken will be better than none at all. Those who have private beaches can easily provide facilities for taking the sun-bath nude, perhaps by boarding up a suitable enclosure. Such an enclosure may also be made in the back-yard by people owning or even leas¬ing property in towns, and by farmers. It should be pro¬vided with air space below all or part of the walls, or should have a shutter-like window on each side.
