Can A Hot Bath Bring On Labour At 39 Weeks

Can a Hot Bath Bring on Labour at 39 Weeks?

I know you’re nearing the end of your pregnancy and looking for any natural ways to bring on labor. Trust me, I’ve been there too! One method that often comes up in the conversation is taking a hot bath. But can a hot bath really bring on labor at 39 weeks? Let’s dive in and explore the topic in-depth.

The Theory

The theory behind using a hot bath to induce labor is that the warm water can help relax your muscles and potentially stimulate the release of oxytocin, the hormone responsible for triggering contractions. Some believe that the heat from the bath can also increase blood flow to the cervix, leading to dilation and effacement.

Relaxation and Stress Reduction

One of the main benefits of taking a hot bath during pregnancy is the relaxation it provides. All those aches and pains can melt away as you soak in the warm water. And when you’re relaxed, your body naturally produces less stress hormones like cortisol. This can be beneficial because high levels of stress hormones have been associated with delayed labor. So, by promoting relaxation, a hot bath may indirectly support the onset of labor.

Increased Circulation

Another possible way that a hot bath could potentially help induce labor is by increasing circulation. Warm water causes blood vessels to dilate, improving blood flow throughout the body. This increased circulation could potentially bring more oxygen and nutrients to the uterus, which may help stimulate contractions.

Oxytocin Release

As mentioned earlier, proponents of using a hot bath to induce labor believe that the heat can stimulate the release of oxytocin, the hormone responsible for triggering contractions. While there isn’t much scientific evidence to support this claim, anecdotal reports from women who have tried this method suggest that it may have worked for them.

The Risks

Before you jump into the bathtub hoping to jumpstart labor, it’s important to consider the potential risks involved. Hot baths can raise your body temperature, and excessive heat exposure during pregnancy can be harmful to both you and your baby. Here are a few things to keep in mind:


Raising your body temperature too high during pregnancy can increase the risk of birth defects and other complications. It’s recommended that pregnant women avoid hot tubs, saunas, and baths that raise their body temperature above 100 degrees Fahrenheit for an extended period of time. So, before you immerse yourself in a scalding hot bath, take a moment to check the water temperature and make sure it’s safe for you and the baby.


Hot baths can cause sweating, which can lead to dehydration if you’re not careful. Dehydration can contribute to uterine irritability and potentially trigger contractions. It’s important to drink plenty of fluids before and after taking a bath to stay hydrated.

Slippage and Falls

As your belly grows larger, your center of gravity shifts, and you may become more prone to slips and falls. Getting in and out of a tub can be tricky, especially if you’re feeling off-balance. To minimize the risk of accidents, consider using a non-slip mat in the bathtub and have someone nearby to assist you if needed.

Frequently Asked Questions

1. How long should I stay in the hot bath?

It’s generally recommended to limit your time in a hot bath to 10-15 minutes. Prolonged exposure to hot water can increase the risk of overheating. Soak for a short period of time and monitor your body temperature to ensure it stays within a safe range.

2. Can a hot bath induce labor if I’m not 39 weeks yet?

While a hot bath can be a relaxing and enjoyable way to ease pregnancy discomforts, it’s unlikely to induce labor if your body isn’t ready. The best approach is to let labor happen naturally when your baby and body are ready.

3. Are there other natural ways to bring on labor?

Yes, there are several other natural methods that may help stimulate labor, such as nipple stimulation, walking, acupuncture, and certain herbal remedies. However, it’s important to consult with your healthcare provider before trying any of these methods to ensure they are safe for you and your baby.

Final Thoughts

As you near the end of your pregnancy, it’s natural to look for ways to encourage the onset of labor. While a hot bath may provide relaxation and some potential benefits, it’s important to approach it with caution. Be mindful of the potential risks, maintain a safe water temperature, and stay hydrated. Remember, every pregnancy is different, and what works for one person may not work for another. Trust your body and the natural course of labor, and consult with your healthcare provider for personalized guidance. Soon, you’ll be cradling your newborn in your arms, and the journey of motherhood will begin.
