Yes, it is a completely safe practice that helps to calm the mind and body. Pregnant women probably get even more relief from floating than most people especially if they are experiencing water retention or feet swelling. The extra weight carried by the mother-to-be can be very stressful due to the forces of gravity. Floating eliminates the negative effects of gravity, which causes joint pain, inflammation, and stress on inside organs. Pregnant women have also reported a reduction of erratic movements of the baby inside the womb. This is due to a phenomenon called the “mirror effect.” The baby is safe and secure inside the womb, while the mother shares a similar relaxing experience in the float tank.
