Pregnant women probably get more relief from the float tank than anyone else. Just lying on a bed can be extremely uncomfortable for a woman in the later stages of pregnancy due to the massive gravitational strain placed on the body. The float tank is a wonderful haven for pregnant women. We do, however, recommend that pregnant women avoid floating during the first trimester. If you have any concerns about the effects of floating on your pregnancy, we ask you to consult and get permission from your physician before you float.
