Preventing Overheating During Pregnancy

Why Is it Dangerous to Get Overheated During Pregnancy?

If you're pregnant and your body temperature goes above 102.2°F (39°C) for long periods of time, there is a risk of birth defects or other pregnancy problems, especially during the first trimester. Later in pregnancy, it can lead to dehydration, heat exhaustion, or heat stroke in the mother.

How Can I Prevent Overheating?

Try to limit activities that would raise your core temperature above 102.2°F (39°C), such as:

  • using saunas or hot tubs
  • taking very hot, long baths and showers
  • using electric blankets or heating pads
  • becoming overheated when outside in hot weather or when exercising

Instead of hot tubs or saunas, take a dip in a cool pool. And it's probably a good idea to stick to warm or only slightly hot baths and showers. Follow your body's cues that you're getting overheated when exercising or enjoying the great outdoors in the warmer months.

What if I Have a Fever?

If you have a fever during your pregnancy, talk to your doctor about ways to lower it.

What Else Should I Know?

If you've already gotten overheated during your pregnancy, don't worry too much about it. Chances are, you removed yourself from the uncomfortable situation quickly and safely.
