Can You Go in a Hot Tub on Your Period? A Complete Guide Backed by Science

Yes, you can absolutely use a hot tub during your period, safely and comfortably. Many women wonder whether it’s hygienic or risky, but with the right precautions, soaking in a hot tub can even help relieve period cramps and stress.

Wearing a tampon or menstrual cup is key to preventing leaks, and practicing good hygiene, like showering beforehand and avoiding shared towels, keeps things safe. Add period-friendly swimwear, and you’re set for a relaxing experience.

Let’s explore the facts, bust some myths, and see how hot tubs and menstrual health can coexist with ease.

What Happens to Your Period in Water?

It’s a common myth that your period stops in water. In reality, water pressure may temporarily reduce menstrual flow, but it does not completely stop it. This is a physiological response, pressure can limit the outward flow, making menstrual blood less visible while you’re submerged. Still, prevention matters. Even diluted, blood may escape once you move or stand, especially in warmer, more active water like a hot tub.

To stay comfortable and confident, consider the following:

Use a tampon or menstrual cup: These internal products collect blood effectively and prevent leakage while in water.
Opt for period swimwear: Designed with absorbent, leak-proof layers, these garments offer added protection and peace of mind.
Choose well-fitting products designed for swimming: Menstrual cups made from safe, non-toxic silicone are ideal for use in hot tubs.
Be aware of hot tub pressure: Jets may affect flow more than still water, so product security is key.

Benefits of Using a Hot Tub During Menstruation

Using a hot tub during your period offers more than just relaxation; it can also provide real physical benefits. The warm water helps to relieve cramps, reduce bloating, and ease muscular tension, making it a gentle and natural treatment for menstrual symptoms.

Research supports these claims:

Hot water can ease period discomfort: A cross-sectional study found that regular intake of hot water significantly reduced cramp severity and improved mental well-being in menstruating women.
Many women already use hot baths as relief: In a 2023 study, 84.7% of Egyptian nursing students reported using hot baths to relieve menstrual discomfort, showing how common and accepted this practice is.
Historical medicine confirms this effect: A 19th-century clinical analysis concluded that warm or hot baths did not increase menstrual bleeding and were effective in pain relief.

Adding light aerobic exercise, such as stretching or gentle movement in the hot tub, can enhance these effects. One randomized controlled trial published in Lancet Public Health demonstrated that physical activity reduces the intensity of primary dysmenorrhea, the most common form of menstrual cramps.

To make the most of your soak, try:

Gentle leg and back stretches while seated in the tub.
Slow breathing exercises to promote relaxation.
A short swim or light aerobic movements beforehand, if your spa allows.

A hot tub during your period isn’t just safe, it’s a great option for boosting both physical and emotional well-being.

Is It Safe? Hygiene and Health Considerations

Using a hot tub during your period is safe, as long as you prioritize hygiene and use the right products. Choosing the correct menstrual protection is essential to prevent leaks and absorb blood effectively while ensuring you feel comfortable.

Here’s what’s safe to use in a hot tub:

Tampons: Effective for blocking menstrual flow, but they must be changed every few hours, never worn for more than eight hours.
Menstrual cups: A popular choice for menstrual cup use in water, these can be worn longer and collect blood instead of absorbing it.
Pads and panty liners: Less ideal for water as they are not absorbent when submerged and can shift or become saturated.
Swimming-specific period products: Newer various types of period swimwear can enhance comfort and security.

It's crucial to choose non-toxic, water-safe options designed for aquatic environments, especially for longer spa sessions. Also, be mindful of product placement, like a tampon string being securely tucked to avoid discomfort or exposure.

Real safety concerns arise only when hot tubs are not properly sanitized:

Some studies discuss risks like Pseudomonas folliculitis and “hot tub lung,” both caused by bacteria in poorly maintained spas.
There have been documented outbreaks of these infections in settings with low sanitation standards.
A recent study by Dahiya et al. (2024)confirms that menstruating women using well-maintained hot tubs face no increased risk.
For general safety, immersion at 40°C for up to 24 minutes was found to be safe even for people with controlled health conditions.

Maintaining a clean spa, especially with natural, bacteria-reducing products like O-Care, ensures a safe and worry-free soak.

Enhance Safety Naturally – The Role of Spa Care Products

The most important thing when using a hot tub during your period is ensuring the water is clean and hygienic. While menstrual products help prevent leaks, the condition of the spa water itself plays a crucial role in safety and comfort. Proper maintenance isn’t just a nice-to-have, it’s a must.

Debunking Myths About Periods and Hot Water

Despite the facts, many women still encounter misleading information about using a swimming pool or hot tub during their period. Let’s separate fact from fiction using scientific evidence and expert insights.

Common Myth 1: Menstruation Attracts Sharks.

This claim has been widely circulated, especially among ocean swimmers. Still, the Florida Museum of Natural History confirms there is absolutely no chance of increased shark risk due to menstrual blood. No data supports this theory, and competitive swimmers and divers regularly train and compete without issue.

Common Myth 2: Your Period Stops Underwater.

Water pressure may reduce menstrual flow, but it doesn’t stop it. When you exit the water or the pressure changes, the menstrual blood can flow again. This is why using period-friendly swimwear, tampons, or menstrual cups is recommended to manage flow discreetly.

Common Myth 3: Hot Tubs Increase Infection Risk for Menstruating Women.

While it’s true that unsanitary tubs can pose a risk to anyone, menstruation itself does not increase susceptibility. A randomized controlled trial by Dahiya et al. (2024) found no elevated risk when hygiene is maintained. This is echoed in decades of safe spa use among women across settings.

Whether in a pool, swimming, or relaxing in a spa, these myths don’t hold water. With the right precautions and products like period-friendly swimwear or internal protection, many women enjoy safe, stress-free water activities during menstruation.

Frequently Asked Questions

1. Can hot tub heat cause your period to be heavier or come earlier?

Warmth from a hot tub may promote blood circulation and muscle relaxation, which can sometimes lead to your period starting a little earlier if you’re already close to the onset. However, there’s no scientific evidence that hot tubs cause heavier bleeding. If anything, the warmth may ease cramps and reduce discomfort associated with menstrual flow.

2. Is it safe to go in a hot tub if you have an IUD during your period?

Yes, using a hot tub while having an intrauterine device (IUD), whether hormonal or copper, is safe. The IUD is placed inside the uterus and is unaffected by external heat or water exposure. Just be sure to use appropriate menstrual protection like a tampon or cup if you’re on your period to prevent leaks.

3. Can hot tubs worsen PMS symptoms like mood swings or fatigue?

Quite the opposite, spending time in a hot tub may actually help reduce premenstrual symptoms. The heat relaxes muscles and promotes the release of endorphins, which can improve mood and reduce fatigue. Light movement or stretching in warm water can also help release built-up physical tension.
