How hot can a spa be when pregnant?

Soaking in a hot bath, spring, or spa pool can raise your core body temperature so it’s important to consider how to stay cool.

During pregnancy, medical professionals often suggest that your body temperature shouldn’t rise above 39°C. Especially during the first trimester, professionals recommend this precaution because a rise in temperature could result in birth defects, such as brain and spinal cord abnormalities.

If the hot pool you are considering has an adjustable temperature, you could turn it down to 36°C or lower. The lower the temperature, the lower the risk.

How long should I stay in the spa while pregnant?

In the first trimester, many medical professionals suggest it is best to be cautious and avoid hot tubs altogether or only use them for a very limited period of time, under 10 minutes. An alternative is to dip your feet in the warm water or sit on the side of the spa for a short period of time.

If you're using the spa pool with friends or family, ask if they'd be willing to reduce the temperature ahead of time. A lower temperature significantly reduces your risk of overheating and will be more comfortable for you.

An average hot tub will take between 30 minutes to 1 hour to reduce in temperature by 1°C. You can kick start the process by leaving the cover off for a few hours, running the jets to allow the water to circulate and adding some cool water or even adding a bit of ice to the water.

Before using a hot tub you don’t own or visiting a hot pool facility, it's a good idea to ask a few questions.

  1. What temperature is the water?
  2. How frequently is the water replaced?
  3. Is the water tested daily using pool strips?

What are my alternatives to a spa when pregnant?

If using a spa is not an option or you have decided not to use one but still want the relaxing benefits of hydrotherapy, then a warm bath is a great alternative. In a bath, much of your upper body will remain out of the water, making you less likely to overheat. Additionally, the water in a bath begins to cool off, as opposed to a hot tub which is designed to maintain a consistent temperature, further reducing any risk of overheating.

If you love the water and want to keep enjoying it when pregnant, you could also try swimming. Swimming is a great low-impact exercise option while pregnant and can help to reduce strain on your muscles while providing great resistance for a workout. Most public pools are kept between 27° to 29°C and often offer fitness classes for pregnancy. If you would rather swim at your own pace jump in a lane and make the most of the relaxing water.


We hope this article has helped you understand the key things to think about before using a spa while pregnant and the great alternatives available.

If you do decide to jump in the spa, remember to keep a close eye on your temperature, stay hydrated and seek the advice of your primary medical provider first for peace of mind.
