Extended periods of soaking in a hot tub or being exposed to excessively high water temperatures can lead to significant risks, including overheating, dehydration, and low blood pressure. These conditions can result in symptoms such as dizziness, fainting, and in severe cases, potential complications like preterm labor or birth defects.
These findings are based on a 2006 research paper published in the National Library of Medicine, which highlights the serious impact of exposure to heated water pools exceeding 39°C (102.2°F) during pregnancy on the health of the unborn baby.
Specifically, individuals exposed to mild heat before the implantation of the embryo or more severely during the first trimester may be at higher risk of developing birth defects or experiencing pregnancy loss.
On average, most hot tubs and portable spas can reach temperatures up to 40.55°C (104°F). However, it is strongly advised against pregnant women using hot tubs and setting the water temperature to such high levels.
To prevent overheating and excessive core body temperature increases, it is recommended to adjust the hot tub temperature to a maximum of 37°C (100°F) or lower. Spending more than 10 minutes in a hot tub with a water temperature of 40°C (104°F) can easily raise the core body temperature beyond safe levels, which is why many healthcare professionals strongly discourage it.
If you are considering using a hot tub during pregnancy, it is crucial to consult with your doctor regarding any associated risks based on your specific health situation. Your doctor will be able to provide guidance on whether the benefits outweigh the potential risks when considering hot tub usage during this stage. Always prioritize safety first!
Safer ways to use your hot tub when pregnant:
If you make the decision to use a hot tub during pregnancy, it is important to take certain precautions to ensure the safety of both yourself and your unborn baby. Here are some guidelines for safely using a hot tub while pregnant:
- Use a hot tub with a temperature of 100°F (35C) or below. In order to prevent overheating and excessive increases in core body temperature, it is recommended to use a hot tub with a temperature of 35°C (995°F) or lower. It is important for pregnant women to avoid hot tubs and hot baths with temperatures exceeding 40°C (104°F) as they can pose significant risks.
- Avoid soaking in a hot tub for more than 10 minutes. It is advised to restrict your hot tub sessions to a maximum of 10 minutes at a time. Prolonged exposure to hot water can lead to an increase in your body temperature, which can pose potential harm to your unborn baby.
- Avoid using the hot tub in the first trimester when your developing baby is most vulnerable. During the first trimester of pregnancy, it is important for pregnant women to exercise caution when it comes to using a hot tub. This is because the baby's development occurs rapidly during this period, and there is a risk of water-borne infections that could potentially harm the developing life.To prioritize safety and well-being, it is advisable to refrain from using a hot tub until after the first trimester. However, if it is necessary to use a hot tub during this time, certain measures should be taken to mitigate risks. Ensure that the hot tub is thoroughly cleaned with chlorine, and regularly monitor the pH levels to prevent the growth of bacteria or any potential hazards. By following these precautions, you can help maintain a safer environment for both you and your baby.
- Make sure the hot tub is properly maintained and sanitized to reduce your exposure to harmful bacteria and chemicals. Pregnant women should be particularly mindful of the presence of germs and bacteria, particularly when using public hot tubs. Ensuring the proper maintenance and sanitization of the hot tub is crucial to minimize the risk of exposure to harmful bacteria and chemicals.Maintaining the hot tub properly entails regular water changes, frequent monitoring of free chlorine levels, a thorough inspection of all equipment and accessories, consistent chemical treatments and water testing, as well as regular disinfection of filters at least every two months.The Centre for Disease Control & Prevention (CDC) recommends maintaining free chlorine levels between 2 and 4 parts per million (ppm), bromine levels between 4 and 6 ppm, and pH levels between 7.2 and 7.8.Despite implementing these measures, it is advisable for pregnant women to exercise additional caution by avoiding heavily crowded hot tubs or spas with questionable upkeep. Ultimately, prioritizing the protection and well-being of both yourself and your baby should always be paramount.
- Keep hydrated while using a hot tub. To maintain hydration, it is important for pregnant women to consume ample water before and after using a hot tub. It is advisable to avoid alcohol or caffeinated beverages, as they can contribute to dehydration. The combination of excessive heat and the natural water retention during pregnancy can lead to feelings of dehydration.Dehydration poses various risks to the developing fetus, including the potential for preterm labor or decreased levels of amniotic fluid. Preventing these issues can be as straightforward as ensuring adequate fluid intake, particularly before and after using the hot tub.
- Get out of the hot tub immediately if you feel uncomfortable. If you begin to experience discomfort or excessive heat while in the hot tub, it is crucial to exit immediately. Take a break and allow yourself to cool down before considering re-entering. When an expectant mother starts feeling any form of discomfort during their time in the hot tub, it is vital to be attentive to these signs and take prompt action.Frequently changing positions or incorporating short breaks during the session can help ensure that the hot water does not pose any risk. Prolonged exposure to high temperatures is not recommended for pregnant women, so if you have been in the hot tub for more than 15 minutes, it may be time to exit.Maintaining awareness of your body temperature is essential for a safe and comfortable hot tub experience while pregnant. If something feels off, such as feeling faint, it is important to trust your intuition and promptly remove yourself from the hot tub.
- Monitor your body temperature. Utilize a thermometer to carefully monitor your body's temperature while enjoying the hot tub. If your core body temperature exceeds 37°C (101°F), it is important to exit the hot tub immediately and cool down.Monitoring your body's temperature serves as a simple and effective method to prevent accidental overheating while in the hot tub. Additionally, it is recommended to consider using a floating hot tub thermometer, which can be placed in the water during your soak. This device will provide you with an accurate measurement of the water temperature, enabling you to regulate your hot tub session and ensure that you do not exceed a safe and comfortable level of warmth.
- Sit on the opposite side of the water jets where the water temperature is slightly lower. For pregnant women, it is advisable to sit on the side of the hot tub opposite to where the water jets are positioned. This area generally maintains a slightly lower water temperature.
- Use caution when getting in and out of the hot tub. Exercise caution when entering and exiting the hot tub to prevent slips or falls. Make use of the handrails available and take your time. Having someone assist you when getting in and out of the hot tub is also recommended.Moreover, it is essential for pregnant mothers to always have a clear exit strategy in case any discomfort or changes arise during their time in the hot tub.
- Make a conscious effort to keep your chest above the water.
To minimize potential risks of using a spa during pregnancy, it is advisable to limit the duration of full submersion and avoid submerging the chest area. If feasible, restrict the submersion to the lower half of your body and exercise caution if you choose to soak above the upper torso and chest level, being mindful of the exposure time.
- Consult your doctor before using a hot tub. Prior to using a hot tub, it is crucial to consult with your doctor or midwife regarding any potential risks or concerns. If you have a high-risk pregnancy, high blood pressure, or other medical conditions, they may recommend against using a hot tub.
