Hot water does not pose any risk to your pregnancy, but due to the high temperature of the water, the blood vessels in the body expand, which are already dilated due to hormonal changes during pregnancy. This leads to a rapid drop in blood pressure, which can lead to feelings of weakness and imminent collapse. Therefore, pregnant women are very sensitive to high water temperature. The same applies in the case of staying in any hot environment (unventilated, breathless room) or during the summer heat.
