Interesting Extremebean! I don't think I could stand it for reasons baglady mentioned-I get too hot but here's a couple things I could find...I think the main thing is they don't know
what the effects could be & it's out of concern for mom's health so it's a no no!
According to a National Institute of Health (NIH) document Solar Radiation and Exposure to Sunlamps and Sunbeds: "Most tanning bulbs sold in the United States for use in sunbeds emit 'substantial doses of both UVB and UVA'(Swerdlow and Weinstock, 1998, citing 'personal communication from industry sources.' Many of the home and salon devices in the 1980s emitted both UVA and UVB radiation, but current devices emit predominantly UVA (FTC,1997; Sikes,1998)."
Some authorities are studying a potential connection between neural tube defects and ultraviolet radiation. They site evidence that shows that the radiation breaks down folate and puts preconceptional and early pregnant women at higher risk for giving birth to a baby with spinal bifida or other types of neural tube defects. One such article, published in 1999 by Jablonski in Medical Hypothesis, concluded that "intense or prolonged periconceptual exposure of women to UV light for recreational or therapeutic reasons should be avoided."
The British Medical Journal in 1997 (Volume 314(7089) published an article by Wright et al. which stated "there can be no doubt that sunbeds are widely used and that they carry a risk of inducing skin cancer. Clearly the higher the ultraviolet light output the greater the risk."
There have been no controlled studies of the direct effects of tanning or tanning beds on pregnant women or their unborn child. In view of the evidence of damage from ultraviolet radiation to the skin of the mother, however, it makes sense to me to avoid this type of activity for the duration of pregnancy.
Few things may make you look or feel healthier then a glowing tan. And with the invention of tanning beds, bronzing your skin can now be done in half the time. However, Bill Wolff, a nutritionist and tanning salon owner from Atlanta, Ga., says a woman in her first two trimesters of pregnancy should not use tanning beds as they can be dangerous to both her and her unborn baby.
"Just as there are advisories for people taking certain medications or with certain medical conditions, warning them against the affects of tanning beds, there are also advisories for pregnant women," says Wolff. "UV rays can affect the skin in many ways. And with the skin of the abdomen stretched due to pregnancy, this area is prone to severe burning and damage. Also, with the hormone changes a woman's body is going through during pregnancy, there is no way to tell how the tanning bed will affect her. It could be anything from nausea and severe headaches to sun sickness, sun poisoning and skin damage. It is best to wait until after the baby is born before visiting the tanning bed."
