A study last year published in the journal DermatoEndocrinology found that tanning salon sunbeds are highly effective in raising serum levels of vitamin D. Those who used the sunbeds attained optimal levels (more than 100 nmol/L) [40ngml] D during the winter.
Another earlier study had also showed similar results, so this research served to corroborate the original finding.
The beneficial effects of sunbed use are numerous:
- Sunbed use strengthens bone. As mentioned above, one study compared 50 subjects who used a sunbed at least once weekly, to 106 control subjects who did not use them. The sunbed users had 90% higher vitamin D levels than non-users. They also had significantly higher bone-mineral density, indicative of stronger bones.
- Sunbed use can control psoriasis and eczema. Research showed convincingly that sunbeds are a valid treatment for psoriasis. And, it also stated another conclusion: Sunbeds could be useful “as a treatment option for atopic dermatitis [eczema], mycosis fungoides, acne, scleroderma, vitiligo, and pruritus, as well as other UV sensitive dermatoses.”
- Sunbed use reduces chronic pain. A study of pain in fibromyalgia patients, conducted by dermatologists, revealed that those who used UV-producing sunbeds experienced a decrease of 0.44 points on a 10 point scale (Likert scale), when compared to those who did not receive UV light. Feelings of well-being and relaxation were also reported among the tanners.
- Sunbeds may help unborn children. Sunbeds are now being recommended for use by pregnant women who will give birth in a winter month, in order to protect the unborn child from osteoporosis during adulthood.
- Sunbed use reduces the risk of clots. In an eleven-year study of the sun-exposure habits of 40,000 women, venous thrombotic (clotting) events were measured. It was found that women who sunbathed during the summer, on winter vacations, or when abroad, or used a sunbed, were at 30% reduced risk of clots compared to those who did not sunbathe.
- Sunbed use is associated with lower breast-cancer risk.
- Sunbed use reduces the risk of death. Perhaps the most important research on sunbeds was a 20-year study: It showed that women who used sunbeds were 23% less likely to die from any cause than women who did not use them.
