We all need vital amounts of vitamin D for good health, but do tanning beds offer comparable amounts to the sun?
This article goes into the two types of rays, UVA and UVB. The healthier of the two are UVB rays, which are more surface level and offer the health benefits of vitamin D. UVA rays penetrate deeper into skin leaving a tan, which is potentially damaging. Most tanning salons are more focused on UVA rays (calibrate their beds to emit 95% UVA rays). UVA rays create the tan, but also the most harmful effects of sun.
