We all have those days where the only thought getting us through the day is of our amazing hot tub at home, calling our names with plenty of bubbles, all the jets on, and a nice glass of wine.

When the day has pushed you to your limits, it might be tempting to get into your hot tub and never emerge out of it again.

Hot tubs have been proven to relax the mind and body and alleviate all stress from the day, so it stands to reason why people might want to remain in the hot tub for multiple hours.

If you think you need an extra dose of hydrotherapy, what’s the harm in staying in for a little while longer?

Well, while hot tubs are great for melting away your problems for a while, there are still risks associated with misusing your hot tub.

We know what you’re thinking – misusing a hot tub? Surely there’s no such thing! – well, unfortunately, there is such a thing, and many of us are guilty of doing it.

Below we’ll be looking into the safe amount of time to spend in a hot tub, as well as some of the risks that can be increased with prolonged exposure to the hot tub.

Knowing When Enough is Enough

The main worry of hot tubs is overheating and therefore dehydrating the body.

As the hot tub temperature is more than likely going to be higher than your internal body temperature, your body temperature will rise and therefore put you at risk of the health issues that we mentioned above.

Big deal, right? Just drink some water after you get out and you’ll be fine!

The Heater and The Pump

Well, actually overheating and dehydration is very dangerous – more worrying than many people make it out to be – and can cause lightheadedness and fainting. If you live alone, this can be very worrying.

Make sure you listen to your body when you’re relaxing in the hot tub.

If you’re beginning to feel uncomfortable, take yourself out of the hot water. You can always get back in once your body temperature has cooled down, so frequent breaks are advised.

How Long Is It Safe?

The majority of hot tub users say that you should only use your hot tub for around 15 to 30 minutes at one time.

We know that this sounds ridiculously short, but that is the safest amount of time to spend in the hot tub.

Having said that, if you’re in desperate need of a longer relaxation period, you can remain in the hot tub from anywhere up to 60 minutes. Any longer than 60 minutes is considered dangerous to your health, so don’t push the time limit no matter how tempting it is.

Factors Affecting Your Time Limit

Don’t be too disheartened just yet! There are a few different factors that could affect how long you’re allowed to remain in your hot tub.

15 to 60 minutes is a good baseline for the majority of people, but your health and circumstance might affect this so keep reading on!

External Temperature

The time of year will affect how long you can remain in the hot tub comfortably.

If it’s wintertime, the external temperature is going to cool down the water considerably more than you were surrounded by the summer heat.

So, winter hot tub sessions will be more comfortable than summer sessions, and therefore they can be longer.

Internal Temperature of Hot Tubs

The temperature of the water is another factor to consider, and this might just be the most obvious one.

If you’re planning to stay in the hot tub for longer than an hour, make sure to turn the water temperature down beforehand and wait for it to successfully reach that degree.

Your Health and Hot Tubs

Be reasonable with your hot tub use and only stay in for as long as you think is necessary for your body.

You’re the person who knows your personal health the best, after all, so you should be able to know your limits and act sensibly once you reach them.

Hot tubs should not be used by pregnant women and people with heart conditions or high blood pressure.

If you have any of these conditions or have been advised by a doctor not to use a hot tub, don’t use one! Why risk it?

If you are in good health; however, you might feel comfortable staying in for longer up to 60 minutes. If you have a health problem, don’t risk staying in for longer because you don’t feel too hot yet.

The heat could be affecting your health issue without you even knowing.

Water Volume Inside Hot Tub

When your body temperature rises from being in a hot tub for a long time, the area that isn’t in the water is the scapegoat for the additional heat.

So, if you sink into the water up to your neck, the only area available to allow heat out of is your face and neck.

This will stop the heat from being able to leave your body as well as if you were only submerged up to your chest.

Therefore you’ll need to get out of the hot tub quicker than if the water volume was lower.

Your Body and Hot Tubs

Children cannot regulate their temperature as well as adults and therefore cannot remain in the hot tub for as long as their parents.

It’s also been shown that women can withstand higher temperatures than men and therefore can remain in hot tubs for longer periods of time.

It is also implied that larger bodies find remaining in hot tubs for longer periods more uncomfortable, whether this being from muscle or fat mass.

Again this comes down to how you feel and listening to your body.


So, how long should you stay in a hot tub for the best results and safety?

The answer is that it depends on your goals.

If you’re looking to relax and ease tension, staying in for around 20 minutes will do the trick.

If you’re hoping to improve your circulation or get rid of aches and pains, aim for 30-40 minutes.

And if you want to achieve all of the above benefits plus enjoy some serious relaxation time, shoot for 60 minutes!

There are plenty of factors affecting how long you can remain safely in the hot tub.

We know that you’re trying to calculate the time by using the best possible version of yourself, so all we ask is that you’re careful and don’t push yourself.

Remember, If you feel uncomfortable, get out of the hot tub and allow your body to cool down.
