Can You Use a Hot Tub When Pregnant? | Hydropool Midlands

When it comes to pregnancy, there are numerous questions and concerns that expectant mothers face, and one common query is about the safety of using hot tubs. The warmth and relaxation offered by a hot tub or jacuzzi can be appealing, but it's crucial to understand how this indulgence might affect both the mother and her unborn baby. 


This blog aims to explore the medical guidance and considerations surrounding the use of hot tubs and jacuzzis during pregnancy. Drawing upon advice from healthcare professionals and current research, we will delve into the potential risks, recommended precautions, and safe practices to ensure the wellbeing of both mother and child. 


It’s always best to check with your doctor and seek expert medical guidance before getting into a hot tub spa when pregnant.


Understanding the Risks

The decision to use a hot tub while pregnant should be approached with a keen understanding of the potential risks involved. Let's explore some of these risks to help expectant mothers make well-informed choices.




One of the primary concerns with hot tub use during pregnancy is the risk of overheating, medically known as hyperthermia. Pregnant women are more susceptible to overheating, and elevated body temperatures, especially during the first trimester, can pose risks to foetal development. Studies have indicated that an increased core body temperature might lead to complications like birth defects.


Dehydration and Low Blood Pressure


Soaking in a jacuzzi hot tub can also lead to dehydration and lowered blood pressure. During pregnancy, maintaining proper hydration is crucial for both the mother's and the baby's health. The hot water can cause extensive sweating, leading to dehydration, which in turn can result in dizziness and fainting, posing a risk to the mother.


Risk of Infections


Hot tubs, if not properly maintained, can be a breeding ground for various bacteria, including those causing Legionnaires' disease, a severe form of pneumonia. Pregnant women have a somewhat altered immune system and may be more susceptible to such infections, which can be harmful to both the mother and the foetus.


In light of these risks, it is imperative for pregnant women to have a comprehensive understanding and seek advice from their healthcare provider before deciding to use a hot tub. While the allure of relaxation and relief from pregnancy aches might be tempting, prioritising safety is paramount.



Medical Recommendations


Navigating the do's and don'ts of pregnancy can be challenging, especially when it comes to understanding the medical recommendations regarding activities like using a hot tub or jacuzzi spa. Let's break down what healthcare professionals say about this topic.


Guidelines from Medical Authorities


The American College of Obstetricians and Gynecologists (ACOG) provides guidance on this matter. They caution against the use of hot tubs during pregnancy, primarily due to the risks associated with high body temperatures. Similarly, the National Health Service (NHS) in the UK advises pregnant women to avoid using hot tubs. These recommendations are grounded in research that suggests a link between elevated maternal body temperature in the first trimester and certain birth defects.


Understanding the Concerns


Medical professionals are particularly concerned about the sustained high temperatures in hot tubs. Unlike a warm bath, where the water gradually cools down, (you may also want to be cautious about using warm baths whilst pregnant) hot tubs maintain a constant high temperature. This constant heat can raise a pregnant woman's core body temperature to levels that might be risky for the foetus, especially in the critical stages of development in the first trimester.


Duration and Temperature


If a pregnant woman chooses to use a hot tub, healthcare providers usually recommend limiting the time spent in the hot tub to less than 10 minutes.

As per the official NHS guidance the water temperature should not go above 95 degrees Fahrenheit (35 °C). These precautions are suggested to minimise the risk of overheating.


Consultation is Key


Most importantly, medical experts advise that pregnant women should consult with their healthcare provider before using a hot tub. This consultation is crucial as it allows for personalised advice based on the individual's health, pregnancy history, and any specific risk factors they may have.

Safe Practices for Hot Tub Use


While medical authorities generally advise against using hot tubs and jacuzzis during pregnancy, some expectant mothers may still choose to enjoy a soak. If you're considering using a hot tub, it's essential to follow certain precautions to minimise potential risks. 


Limit Your Time


The most critical factors are the duration of time spent in the hot tub and the heat of the hot tub. It's advisable to limit your soak to less than 10 minutes. This helps reduce the risk of raising your core body temperature too much, which is especially important during the first trimester.



Monitor the Temperature


Ensure that the hot tub's water temperature is not higher than 95 degrees Fahrenheit (35 degrees Celsius). Temperatures above this can increase the risk of overheating. Some hot tubs are preset at higher temperatures, so it's important to check and adjust the settings accordingly.


Stay Hydrated


Dehydration is a risk when using a hot tub. Drink plenty of water before and after your soak to ensure you stay well hydrated. Avoiding or limiting caffeine and alcohol, which can contribute to dehydration, is also wise.

Enter and Exit Carefully


Pregnancy can affect your balance and coordination. Be extra cautious when entering and exiting the hot tub jacuzzi to prevent slips and falls.


Pay Attention to Your Body


Be mindful of how you're feeling while in the hot tub. If you start to feel dizzy, nauseous, or uncomfortably hot, exit the hot tub immediately. These could be signs of overheating or dehydration.


Post-Hot Tub Care


After getting out of the hot tub, it's a good idea to cool down gradually. Avoid jumping into a cold shower immediately, as the sudden temperature change can be a shock to your system.


Regular Maintenance


Ensure that the hot tub is well-maintained and the water is regularly treated and tested for bacteria. This reduces the risk of infections, which pregnant women may be more susceptible to.

Consider a self-cleaning hot tub, to make maintenance easier.


Listening to Your Body


Recognising Overheating Signs


Overheating is a primary concern with hot tub use. Signs of overheating include feeling excessively warm, sweating profusely, dizziness, nausea, and headache. If you experience any of these symptoms while in a hot tub, it's essential to get out immediately and cool down.


Understanding Dehydration Symptoms


Dehydration can occur quickly when using a hot tub. Symptoms include dry mouth, feeling thirsty, reduced urine output, dark yellow urine, and feeling lightheaded. Staying well-hydrated is key, and if you notice signs of dehydration, increase your fluid intake.


Monitoring for Dizziness or Faintness


Changes in blood pressure and dehydration can lead to dizziness or fainting, which is particularly risky during pregnancy. Be aware of these signs and take them seriously. If you feel dizzy or lightheaded, it's time to exit the hot tub and rest.


Paying Attention to Discomfort


Pregnancy can bring about various aches and pains. If you feel any discomfort or pain while in the hot tub, don't ignore it. Pain can be a sign that something isn't right, and it's better to be cautious and stop what you're doing.


Being Aware of Your Limits


Every pregnancy is unique, and what may be comfortable for one person may not be for another. Understand and respect your limits. If you feel that the hot tub isn't suitable for you, trust that instinct.


Seeking Medical Advice When Necessary


If you experience any unusual or concerning symptoms after using a hot tub, don't hesitate to seek medical advice. It's always better to be safe and consult with a healthcare professional.




The decision to use a hot tub during pregnancy should be made with careful consideration and consultation with a healthcare provider. While hot tubs offer relaxation and certain health benefits, the risks associated with high temperatures, such as overheating and potential harm to the developing foetus, cannot be overlooked. 


Pregnant women who choose to use a hot tub should adhere to guidelines like limiting the time spent in the tub, monitoring the water temperature, and paying attention to their body's response. Ultimately, the safety and well-being of both the mother and the baby should be the paramount concern when deciding whether to use a hot tub during pregnancy.
