There are special lamps, I worked in an office where some people had them. I knew others who still felt just as good if they laid in a tanning bed for ten minutes. You have to realize that many people don't really enjoy the cold and when they live through months of little daylight or sunshine, the warmth of the bed and the brilliant mimic of the sun, really does perk them up. You don't have to lay in a tanning bed and fry either...we should also remember that doctors are now recognizing that we have reduced our natural vitamin D intake so much that it is affecting us in many negative ways. Vitamin D is absorbed by the skin during direct exposure to sunlight - now millions suffer from a deficiency from staying out of the sun or using tons of sunscreen.
About 20 minutes a day of sunshine without sunscreen, not a peak times, is all you need to absorb...we no longer get that and instead rely on tablets to fill it...I don't advocate tanning beds or baking in the sun either, but I do recognize that people can use both to make them feel better and I don't believe it has anything to do with race. sammieswife
