Ice baths and cold plunges have become increasingly popular in recent years for their ability to help alleviate stress and muscle pain. However, if you’re pregnant, then it might not be your best option.

What Are Ice Baths?

An ice bath is a form of cold water immersion (CWI) where you submerge your body in ice-chilled water, typically ranging from 33°F to 60°F (0.5°C to 15.5°C). It has gained popularity thanks to figures like Wim Hof, "The Iceman," and is often praised for its potential recovery benefits. These include reducing muscle soreness, numbing pain, and possibly enhancing mood.

The primary idea behind an ice bath is that the cold causes blood vessels to constrict, which helps reduce swelling and pain after intense physical activity. Some people also believe that it offers long-term benefits, such as improving immune function and reducing inflammation [*][*].

What Are Cold Plunges?

A cold plunge is similar to an ice bath but generally less intense. The water temperature typically falls between 53°F to 60°F (12-15°C), making it a more manageable option for beginners or those who prefer a gentler experience. Cold plunge sessions usually last from 3 to 15 minutes, depending on your tolerance.

Cold plunge tubs are increasingly popular because they often have adjustable temperature settings, allowing you to fine-tune how cold (or not) you want the water. While less extreme than an ice bath, cold plunges still offer similar benefits. The moderate cold helps reduce inflammation, boost circulation, and accelerate muscle recovery, while also potentially improving mood and supporting the immune system [*][*].

Are Ice Baths Safe When Pregnant?

No, ice baths are not safe during pregnancy. While cold water immersion has benefits, it can also interfere with blood flow to the fetus and increase risks like preterm labor or stillbirth. It's best to avoid extreme cold exposure while pregnant.

Cold exposure, such as ice baths, causes the body’s blood vessels to constrict, which is a natural response to intense cold. This constriction happens as the body tries to preserve core heat and maintain internal temperature stability. However, when you're pregnant, this response can affect blood flow in ways that are not ideal for your baby.

When you do something like an ice bath, the cold causes your blood vessels to tighten, which can reduce blood flow to the placenta, the organ that gives your baby oxygen and nutrients. Less blood flow could lead to problems like poor fetal growth or even preterm labor. Your body already has a harder time regulating temperature during pregnancy, so adding stress with extreme cold can mess with your hormones and put extra strain on your pregnancy [*][*].

What Are the Potential Benefits of Ice Baths While Pregnant?

While it is generally not recommended to do cold plunges or ice baths during pregnancy, there are still a few common problems that come up during pregnancy that they may help with.

Relieving Inflammation

During pregnancy, many women experience joint inflammation due to the added weight and changes in hormone levels. Cold plunges, or ice baths, are often used for relieving joint inflammation in non-pregnant people, but their effect during pregnancy is more complicated.

While cold exposure can reduce swelling and numb pain by constricting blood vessels, it can also limit blood flow to the placenta. The body’s ability to regulate temperature and blood flow is altered while pregnant, so using cold therapy might cause more harm than good [*].

Stress Management

Cold water immersion can have a big impact on mood and stress. When you dive into cold water, your body goes into a cold shock response, your heart rate goes up, you start breathing faster, and your nervous system gets activated. This triggers changes in brain networks that help improve alertness, focus, and overall mood.

After a cold plunge, people often feel more energized, motivated, and less stressed or anxious. It’s also been linked to a reduction in symptoms of depression, like low energy and emotional distress [*].

What Are the Risks of Ice Baths While Pregnant?

Extreme cold exposure, like ice baths or cold plunges, can pose several risks during pregnancy, including an increased chance of preterm birth and restricted blood flow to the placenta. Here's a closer look at how these cold therapies might affect your pregnancy.

Increased Risk Of Preterm Birth

Taking ice baths during pregnancy might raise the risk of preterm birth, especially if you're exposed to extreme cold early on.

A study by the National Institutes of Health found that women who experienced very cold temperatures during the first seven weeks of pregnancy had a higher chance of delivering early. The research showed a 20% increased risk of delivering before 34 weeks for those who were exposed to cold early in their pregnancy.

The stress caused by the cold could mess with blood flow to the uterus and affect how the placenta develops, which might trigger early labor. While more research is needed, the body’s response to cold stress could make pregnancy complications worse [*][*].

Restricted Blood Flow to the Placenta

Exposure to extreme cold, like during ice baths or cold plunges, could mess with blood flow to the placenta in pregnant women.

When you're exposed to really cold temperatures, your body naturally constricts blood vessels to keep heat in, which means less blood (and oxygen and nutrients) gets to the uterus and placenta. This can be especially concerning later in pregnancy when the placenta is doing a lot of the heavy lifting for the baby.

Studies have shown that being exposed to temps below the normal range, particularly in the later stages of pregnancy, can raise the chances of having a preterm birth or a baby with low birth weight [*].

Increased Risk of Underweight Baby

Exposure to extreme cold temperatures during pregnancy can increase the risk of delivering a baby with low birth weight as well.

Since the placenta is responsible for delivering oxygen and nutrients to the baby, a decrease in blood flow can restrict the baby's growth, leading to low birth weight.

Studies have shown that pregnant women exposed to low ambient temperatures are more likely to have underweight babies, especially if the exposure happens during late pregnancy when the baby’s growth is most critical [*].

What Are Some Precautions You Can Take?

While subjecting your body to extreme temperatures during pregnancy is not recommended, there are some ways that you could limit any potential harm that could come from cold plunges.

Limit Cold Exposure Duration

If you do choose to try cold exposure, keep sessions short (no longer than 3-5 minutes). This can help reduce the strain on your body and avoid overwhelming your system, which might affect blood circulation to the placenta [*].

Avoid Early Pregnancy Cold Plunges

The first trimester is a critical period for fetal development, and exposure to cold temperatures during this time has been linked to an increased risk of preterm birth. It’s best to avoid cold plunges or ice baths during this stage [*].

Consider Water Temperature

If you decide to engage in cold water immersion, choose a more moderate temperature (above 50°F/10°C) instead of ice-cold water. A cold plunge tub with adjustable settings can allow you to fine-tune the temperature to ensure it's not too extreme [*].

Consult Your Healthcare Provider

Before attempting any form of cold therapy during pregnancy, it's always a good idea to discuss it with your doctor or midwife. They can offer personalized advice based on your health and pregnancy progression.

Ice Bath and Cold Plunge Alternatives

If you're looking for a safer way to ease muscle and joint pain during pregnancy, there are plenty of options that are gentler than ice baths.

Here are some alternatives that can help reduce stress, pain, and inflammation without the risks of submerging your entire body in freezing water.

Cold Shower

Cold showers can be an easier, more comfortable option for easing muscle and joint pain during pregnancy instead of ice baths.

Cold showers can help reduce inflammation, relieve pain, and boost circulation, which makes it perfect for sore muscles if you don’t want to have to immerse your entire body.

Plus, you can adjust the temperature and how long you stay in, making it a gentler and more manageable option compared to a full-on ice bath.

Cold Compress or Ice Pack

Using a cold compress during pregnancy can be a safer and more manageable alternative to cold plunges, especially for targeting specific areas of discomfort.

A cold compress helps reduce inflammation and numb pain, which is ideal for new or acute injuries, like strains or sprains.

It’s also effective for conditions like headaches, swelling, and joint pain.

The benefit of using a cold compress over a cold plunge is that it allows for more controlled application, so you can target problem areas without overwhelming your body with an extreme temperature change.

For best results, apply the cold compress for about 10-15 minutes, ensuring a cloth or towel is between the skin and the cold source to prevent frostbite or discomfort [*].

Warm Compress

On the other hand, a warm compress can be a better option for dealing with chronic or lingering discomfort during pregnancy. Warmth helps improve blood flow, relax tight muscles, and soothe aches, making it ideal for conditions like muscle knots, tension headaches, or even cramps.

Since it increases circulation, a warm compress can be especially beneficial for relieving stiffness in joints and muscles that have been under tension for a while.

A warm compress is a safer alternative because it’s gentle and less likely to shock your body compared to a cold plunge.

To use it effectively, aim for sessions of no more than 20 minutes, and ensure the temperature is comfortable to avoid burns or overheating [*].

Yoga

Yoga is another safer and gentler alternative to cold plunges for managing stress and relieving muscle or joint pain during pregnancy.

Unlike cold plunges, which can be intense and uncomfortable, yoga helps relax the body through slow, controlled movements, breathing, and mindfulness. It stimulates the parasympathetic nervous system, reducing stress, lowering heart rate, and easing muscle tension without any harsh impact.

What makes yoga especially great during pregnancy is that it can be easily adjusted to your comfort level. It targets both physical relief and mental calm, helping you manage stress and discomfort in a safe, sustainable way. Plus, it can improve flexibility, reduce pain, and promote overall well-being [*].

The Bottom Line

While ice baths and cold plunges are popular for pain relief and recovery, they are not safe during pregnancy due to risks like restricted blood flow to the placenta, which could lead to complications such as preterm birth or low birth weight.

Instead of extreme cold exposure, there are safer alternatives like cold showers, cold compresses, warm compresses, and yoga. These options can help reduce inflammation, relieve muscle and joint pain, and manage stress without the potential risks associated with cold plunges.
