Can heat be applied to the tummy during pregnancy?

When we are thinking of getting into the bathtub covered in warm water or when our stomach hurts and we remember that we have a hot water bottle that has always helped us to relieve pain, the big question comes to mind: Can we apply heat on the belly when we are going through a pregnancy? The answer is yes, as long as it is moderate heat and for a limited time.

That is, they should not exceed 37,7ºC and we should not apply heat for more than 10 minutes in the case of hot water or more than 20 if we are talking about water bags or cherry stone pillows. Remember that the body temperature during pregnancy should not exceed 38,9ºC, not even with fever.

Our body is in full transformation and we pay much more attention to the signals it sends us. We are more cautious about activities that at other times in life we ​​would consider absolutely harmless. In fact we stopped doing a lot of things for fear of harming the baby. Sometimes it is not about stopping doing something but adjusting it to this beautiful moment in life.

Moderate heat on the belly brings us more benefits than risks

As we have seen, during pregnancy we do not have to stop applying moderate heat on the belly. The sources of heat that come from hot water bottles, cherry pit pillows or a hot shower can have beneficial effects because favor, muscle relaxation. The heat allows vasodilation and generates an influx of blood in the treated area, reducing the contraction of the organ.

For know if the water temperature is adequate if we do not have a thermometer that can be submerged in water we can do the test with the foot. If we can get into the water normally, the water is fine. If we have to do it little by little and gradually it means that it is too hot. Touch wait for it to cool down.

This kind of heat is not moderate, it is too strong and it is better to avoid it during the pregnancy. Excess heat can cause certain malformations in the baby, affecting the development of the spinal cord, the spinal column or the brain and can even cause an abortion, especially in the initial stages.

As for the heat sources for ease the pain, Electric blankets are usually not recommended during pregnancy because many of them have temperatures higher than 37,7ºC. Even so, there are electric blankets with various temperatures and the minimum is usually lower than this value. We must pay attention to the temperature we use.

Hot water bottles or cherry pit pillows commonly used for tummy or back pain they are not large enough to change body temperature. They are considered safe for pregnancy. Anyway, it is better to limit the time and use them at most 20 minutes and repeat it every 4 hours.

First and second trimesters

During the first and second trimester of pregnancy the local heat on the belly helps to relieve pelvic pain caused by small uterine contractions and intestinal colic. It can also be useful in case of indigestion or difficult digestion. But always remember the limits of temperature and time that I have mentioned before.


Third trimester
