Why should hot baths during pregnancy be avoided?

Hot baths during pregnancy are best avoided because of the risk of overheating and the increased risk of dizziness and fainting. A significant rise in your core body temperature, particularly during the first 12 weeks, might interfere with your baby’s development.

How to take a bath during pregnancy

As long as your bath is warm, and will not raise your core body temperature beyond 39 degrees C for more than 10 minutes, you can still enjoy some down time in the tub. In fact, relaxing in the bath can be hugely beneficial for expectant mothers easing pregnancy aches and pains.

Checking the temperature

Verify the water temperature by dipping in your elbow (more sensitive to heat than your fingertips or toes) before getting in - which is also good practice for when baby arrives too. If you want to be certain of the water temperature, you could invest in a bath thermometer. To be on the safe side, water temperature should be no greater than body temperature, around 37 degrees.

If you are craving something a little warmer, it’s okay to have a short, hot shower as long as you don’t stay in it too long - and it’s not excessively hot and steamy.

Can I go into a hot tub when pregnant?

Whilst there is limited research on whether you can go into a hot tub when pregnant, it is advised to avoid them because of the risks of overheating, dehydration and fainting.

Can I have a jacuzzi or sauna while pregnant?

Jacuzzis, saunas and hot tubs should also be avoided throughout pregnancy because of overheating, dehydration and fainting risk. They are actually be far worse than a hot bath, because unlike bath water which will begin to cool once you stop adding to it, the temperature in a jacuzzi, sauna or hot tub remains at a constant heat. Your core temperature rises because your body becomes ineffective at cooling you down through sweating.
