Is it normal for a pregnant woman's body temperature to rise?

Dr. Jeanne Morrison, PhD
Family Practitioner

It is common for a woman’s body temperature to change during pregnancy. During pregnancy the woman's body generates additional heat due to:

  • Increased metabolism
  • Elevated levels of hormones such as progesterone
  • Increased workload on the woman’s body a result of extra weight as the pregnancy progresses as well as the processing and fetal nutrients and waste products

Simultaneously the woman has increased peripheral circulation which leads to dissipation of heat from the body. Therefore it is not unusual that the combination of these factors lead to pregnant women feeling HOT yet having a measured body temperature within the normal range.

However while a slight increase in body temperature is not a concern, any time a pregnant woman’s temperature is 100.4 F or greater the healthcare provider needs to be contacted and the cause of the elevation identified and treated.
