Can You Go in a Hot Tub When Pregnant in the UK?

Pregnancy is an exciting time, but it also raises many questions about what’s safe for both mum and baby.  One common concern among expectant mothers in the UK is, “Can I go in a hot tub while pregnant?”

While the idea of soaking in a hot tub to ease aches and pains is tempting, using one during pregnancy comes with potential risks. In this guide, we’ll explore whether it’s safe to use a hot tub during pregnancy in the UK, why healthcare professionals often advise against it, and what precautions you can take if you decide to use one.

In the UK, most health experts advise against using hot tubs during pregnancy, especially in the first trimester, because of the risk of overheating. Hot tubs can raise your core body temperature quickly, which could potentially impact fetal development and increase the risk of complications. However, if managed carefully, there may be ways to enjoy a soak under safer conditions.

We have created this guide to give a view of the guidance offered but we do not recommend our pregnant customer use hot tubs.

Why Can’t Pregnant Women Go in Hot Tubs?

The primary concern is the risk of hyperthermia, or an elevated core body temperature.  Hot tubs in the UK are typically set to temperatures of 38°C (100°F) or higher, and sitting in this hot water can raise your body temperature above safe limits.  Prolonged exposure to these high temperatures can be dangerous for both you and your baby.

Here are some reasons why elevated body temperature during pregnancy can be harmful:

• Risk to Fetal Development: High body temperatures during early pregnancy may increase the risk of neural tube defects in the baby. In the first trimester, the baby’s brain and spinal cord are developing, and prolonged exposure to heat can interfere with this process.
• Dehydration and Dizziness: Soaking in a hot tub can lead to excessive sweating, which may cause dehydration. Pregnant women are more susceptible to dizziness and fainting, and overheating can exacerbate these symptoms.
• Preterm Labour: Although rare, some studies suggest that extreme heat exposure, particularly later in pregnancy, can cause contractions and increase the risk of preterm labour.

How Long Can You Go in a Hot Tub When Pregnant in the UK?

If you decide to use a hot tub while pregnant, it’s essential to limit the time spent in the water. UK health professionals recommend staying in a hot tub for no longer than 10 minutes at a time to avoid overheating.

If you begin to feel lightheaded, flushed, or uncomfortable, it’s important to get out of the water immediately. Overheating can happen quickly, so pay attention to how your body feels.

To reduce risk, follow these tips:

• Monitor the Water Temperature: Keep the water temperature below 35°C (95°F). This lower temperature is safer for pregnant women while still allowing you to enjoy the warm water.
• Stay Hydrated: Drink plenty of water before and after using a hot tub to stay hydrated and help regulate your body temperature.
• Limit Exposure: As mentioned, keep your soak to 10 minutes or less, and if you feel overheated or lightheaded, get out immediately.
• Keep Your Upper Body Cool: If possible, sit so that your upper body, including your chest and arms, is out of the water to help maintain a safe body temperature.

Can I go in a hot tub if I’m pregnant in the UK?

Whether you can safely use a hot tub during pregnancy in the UK largely depends on how closely you control the water temperature and how long you stay in.  Pregnant women should avoid allowing their core body temperature to rise above 38.9°C (102°F).

To help ensure safer hot tub use, you can:

• Use a Thermometer: Invest in a water thermometer to ensure the temperature stays below 35°C (95°F).
• Limit Soak Time: Limit your hot tub sessions to 5-10 minutes.
• Avoid the Jets: Hot tub jets can increase your circulation and raise your body temperature faster, so consider turning them off.

The general advice from healthcare professionals across the UK is to avoid hot tubs during pregnancy, particularly during the first trimester when the risks are greater. However, some women may find it safe to use a hot tub in later pregnancy with precautions, provided their healthcare provider approves.

If you’re thinking about using a hot tub while pregnant, it’s a good idea to discuss it with your midwife or GP first. They can provide personalised advice based on your health and any specific pregnancy concerns.

If you still want to enjoy a soak, consider these safer alternatives:

• Warm Bath: A warm bath at home, with water temperatures below 37°C (98.6°F), offers a safe way to relax. Unlike hot tubs, the water will gradually cool, reducing the risk of overheating.
• Foot Soak: For swollen feet, a simple warm foot bath can provide relief without raising your core body temperature.

Conclusion
While hot tubs can be a relaxing escape, they come with risks for pregnant women due to the possibility of overheating. UK health professionals advise avoiding them, especially in the first trimester, to protect both mum and baby. With careful management, a short soak may be safe later in pregnancy.
