How Long Can You Stay in a Hot Tub?

While there are no hard and fast regulations for how long you may safely soak in a hot tub, there are some suggestions, such as being aware of certain elements that may increase your risk of danger.

There's nothing better than a relaxing soak in your hot tub after a long day at work. Hot tub owners can dream all day of that moment when they can finally sit back and relax in the hot water.

Though spending time in a hot tub has been shown to provide health advantages, users should be aware that there are limitations to making the experience safe.

While there are no hard and fast regulations for how long you may safely bathe in a hot tub, there are some suggestions, such as being aware of certain elements that may increase your risk of danger.

At Epic Hot Tubs, our team is committed to helping you understand everything about hot tub safety. We're sharing how long you can stay in a hot tub and the side effects of staying in too long.

Factors To Consider When Soaking in a Hot Tub

Hot Tub Temperature

The most important factor in choosing a safe soak length is the hot tub temperature. Sitting in a hot tub of 98-degree water is unlikely to damage you because the temperature is close to your average body temperature.

However, if the water temperature is higher than the normal temperature, then sitting in it for extended periods can have side effects.

When it comes to calculating how long you should soak, the general guideline is that the greater the temperature, the shorter the hot tubbing session.

Personal Health

Another aspect influencing how long you can stay in the hot tub is your general health or physical condition. For instance, pregnant women should refrain from sitting in high-temperature water for an extended period.

People with particular health risks, such as high blood pressure, heart disease, diabetes, or circulation difficulties, should consult their doctors about hot tub safety before using a hot tub.

Additionally, if someone has sensitive skin, they should also consult a dermatologist to avoid skin irritation in the hot tub water.


A healthy adult can spend the suggested amount of time in a hot tub. However, depending on their age and the temperature of the water, children should not be allowed to stay in a hot tub for longer times.

Similarly, elderly people who are more prone to heatstroke and decreased blood pressure should refrain from soaking in a hot tub for long periods.

Position in the Hot Tub

If you are in good health, it's fine for you to use your hot tub at a temperature of 102°F for as long as you want. However, if you're over 65, talk to your doctor about your potential limitations.

Teenagers can soak in a hot tub just as long as adults, but children under the age of 12 can't. They simply don't sweat enough to cool down their bodies. Kids aged five to 12 should only be allowed in the hot tub if the water is set at 98°F or lower. For a safer experience in higher temperatures, have your children only partially submerged in the hot tub on the jump seat or bench.

The Outside Temperature

With regards to an outdoor hot tub, soak times also depend on the outside temperature. For example, if it is chilly outdoors, your body may naturally cool itself at a rapid rate, allowing you to spend a longer time in the tub. On the other hand, you should avoid a long soak on a particularly hot day to prevent dehydration.

How long should I stay in a hot tub?

The average healthy adult doesn't normally feel any adverse side effects after soaking in a hot tub for 30 minutes. But does that mean you should go on soaking? It's always better to be on the safe side. That's why we recommend taking a short break every 20-30 minutes.

Finally, how long you soak relies entirely on your degree of comfort. If you feel fine, you most likely are. If you start feeling dizzy, dehydrated, or nauseous, your body's telling you it's time for a break.

What happens if you stay in a hot tub for too long?

To use a hot tub safely, you need to be on the lookout for any signs your body might be giving you. These can include:

Feeling Dizzy

If you start to feel dizzy or lightheaded during hot tub use, it might be a clue that your body is getting hotter than you realize. Get out and take a 15-minute walk to cool yourself.

Feeling Nauseous

Heat exhaustion or heat stroke can produce nausea and vomiting in some people. However, this isn't always the case. Even if you don't think the symptoms are related to heatstroke, nausea is one of the body's warning indications that you should leave the spa and drink plenty of cold water.

Irritated Skin

If you notice your skin reddening or burning, it is also a sign that you should exit the hot tub. Alongside the hot water, there are often hot tub chemicals that can irritate your skin. Though it may be nothing more than a heat rash, you should interpret it as a message that your body wants to cool down.

Lowering of Blood Pressure

Symptoms such as dizziness, nausea, fainting, an inability to concentrate, or blurred vision could also indicate a decrease in blood pressure.

If you feel your body sending you any of these signals, it is a sign that you've been in the hot tub too long and it's time to get out.
