How Long Can I Stay Inside a Hot Tub? Check These 5 Factors

Make the most of all your hot tub sessions by soaking for the perfect amount of time. The time that you spend enjoying a hydrotherapy session can depend on a number of factors.

While it’s often suggested that you can stay inside a hot tub for anywhere from 15-45 minutes, this amount truly depends on your health, age, preference, and tolerance.

In this article, we’ll take a closer look and help you determine the right time for you.


If you prefer to soak at the maximum recommended setting — 104°F  — the duration of your dip needs to be scheduled accordingly.

While this temperature is safe for healthy adults, you should remain immersed for no more than 20 minutes at a time.

If you prefer a longer spa experience, you’ll need to lower the water temperature accordingly.


If you’re a healthy adult, it’s safe to use your spa at 102°F for as long as you wish. If you’re over 65, even if you’re in good health, you should consult your doctor to determine what’s right for you.

In many cases, you’ll get the green light to stay in the spa as long as you’re comfortable and feeling well.

As a general rule of thumb, most hot tub sessions last between 15 and 45 minutes. If after 45 minutes you want to keep soaking, we recommend stepping out for a bit to give your body a break. Hydrate, rest and then enter the spa again.

Children, however, aren’t so lucky. While teens can soak just like adults, children 12 and under can’t. They simply don’t sweat enough to be able to cool their bodies down.

Kids aged five to 12 should only be permitted in the hot tub if the water is set at 98°F or cooler. If you don’t like the water that cool, have your kids do partial immersion on your hot tub’s bench or jump seat.


Children aren’t the only demographic that need to exercise caution with hot tubs. Pregnant women should too.

No matter how good it feels to ease your aches and pains in the spa, if you’re pregnant, you should keep the water set at 101°F or below.

Medical experts also urge pregnant women to soak for no more than 10 minutes at a time.


The hotter you like your spa, the more at risk you are of dehydration. That’s why it’s so imperative that you take a cool drink with you when you head out to the hot tub.

By sipping at it throughout your spa time, you can replenish all the fluids you lost sweating.

Just remember, you should never drink alcohol while in your spa. Alcohol is dehydrating, making it and your hot tub a bad combination.


Anyone with high blood pressure, heart disease, diabetes or circulatory problems should not use their hot tub until they’ve spoken with their doctor. The same goes for those taking anticoagulant medication or pills that make them drowsy.

Once you receive your doctor’s advice for your safety, you should follow it to a T.

If you are of good health and your doctor has approved the use of a hot tub, you should still monitor how you are feeling when staying in for a longer soak or using the spa at a higher temperature.

If you start to feel dizzy, nauseous, or lightheaded, carefully exit the spa and find a seat to rest in.


Once you know how long to stay inside a hot tub and use it safely, you can really start to enjoy the benefits of hydrotherapy.
