Does sitting out in the sun pose a threat to my baby?

Alexander Kofinas M.D.

For the most part, the answer is no. However, because during pregnancy the maternal skin vessels are dilated to help the mother eliminate the additional heat produced by the baby, pregnant women are more prone to suffering heat strokes if they remain in the sun for an excessive period of time (in this case sunscreen does not help). It is therefore recommended that pregnant women avoid direct sun exposure for more than a few minutes at a time.
