Can going to the tanning bed cause problems while being pregnant?

There is no hard evidence suggesting that tanning during a pregnancy will cause harm to the unborn baby, but it is strongly advised that you speak with your doctor first. The heat associated with lying in a tanning bed can be potentially harmful for the baby and mother. Prolonged heat exposure can cause overheating (hyperthermia) which has been associated with some spinal defects of the fetus.
