Tanning can increase vitamin D levels, but most tanning beds only expose the skin to UVA rays, which do not help in vitamin D production as much as UVB rays. Natural sun exposure is the best way to promote healthy vitamin D levels.
When the sun hits unprotected skin, it activates the cholesterol that synthesizes vitamin D in the body. Ultraviolet light from the sun is a natural way to increase vitamin D levels within the body as long as the skin is not overexposed. Some salons and spas have promoted tanning and vitamin D production to increase sales, since vitamin D is a necessary nutrient in human health. Indoor tanning can produce vitamin D, but the main benefits come from a specific wavelength of UV light, making it crucial to determine which light source is being exposed to the skin through tanning beds to increase the benefits of UV light. vitamin D levels.
The connection between tanning and vitamin D stems from the fact that exposure to ultraviolet light produces vitamin D, an important vitamin that has been shown to fight cancer and help with blood sugar metabolism. The most natural source of vitamin D is the sun, and the sun is sometimes prescribed as a natural way to treat vitamin D deficiency. However, many tanning bed manufacturers take advantage of the feeling of this healthy vitamin by marketing their products as a good way to produce vitamin D. As tanning exposes the skin to ultraviolet light, many consumers believe it is the best way to promote vitamin D synthesis. during the winter months or when sunlight levels or low.
Most tanning beds expose the skin to ultraviolet A rays that are most associated with tanning the skin. These rays, however, do not help in the production of vitamin D as much as their equivalent ultraviolet B rays. UVA tanning also promotes skin wrinkling and can be more damaging to the epidermis. Tanning and vitamin D production may have a low rate of effectiveness due to these factors and may also increase the risk of skin cancer if exposed to high levels, unless an indoor tanning bed also contains equal or greater amounts. of UVB.
Natural sun exposure provides not only UVA rays, which penetrate deep into the skin, but also UVB rays. This important ray is often missing from many tanning beds because it does not contribute to tanning effects. Using UVB tanning and vitamin D promotion is much easier because UVB rays are what trigger the cholesterol component to produce vitamin D in the body. There are very few tanning bed manufacturers that use UVB rays in their tanning systems, making indoor tanning a poor way to promote healthy vitamin D levels in the body.
