Ultraviolet Bath, Russia
This Month in Photo of the Day: Images from the National Geographic Archive
Make-believe summer lasts for a minute or two as kindergarten children in sunless Lovozero bathe in ultraviolet light. Brief exposure to UC radiation provides the children with vitamin D, normally supplied by sunlight. The "sunshine vitamin" strengthens young bones.
