Becoming overheated throughout your early months of being pregnant can be both unhealthy for not only you but also your unborn child. Current research has indicated that a slight raise in your immediate body temperature during the early stages of fetal organ development can possibly lead to newborn birth defects. This series of academic studies were accomplished upon pregnant women whose measured high temperatures were more a result of illness rather then the use of hot baths.
Nevertheless, when you are pregnant becoming overheated presents a problem in that it often develops into lightheadedness. Keep in mind, that should you begin to feel faint, immediately get out of the tub or hot bath. It is commonly understood that a pregnant women in general has a more difficult time maintaining a cool body temperature as it is, thus they are more apt to pass out after getting overheated in a hot tub, or even worse the potential exists for placing the unborn baby under stress or interfering with its normal development. As a result it is recommended that expectant mothers avoid the potential for raising their body temperatures when pregnant.
