Water Temperature

Water temperature plays a key role in determining how long you can stay in a hot tub. The higher the temperature the less time you can spend in the tub. Hots tubs operate at a temperature of 100-102°F. However, the temperature can vary depending on personal preference.

Some people like to increase the temperature above this range while others prefer something cooler. Either way, high temperatures will shorten your time in the tub and lower temperatures will lengthen the duration of your session.  Check out our full guide – Hot Tub Water Temperature.

Outdoor Temperature

The outdoor temperature and weather conditions will affect how long you can spend in a hot tub. The ambient temperature will determine how long you can comfortably remain in the tub. And, if the device is located outdoors, the prevailing weather conditions will play a role. Wind, rain, and extreme weather events can bring an abrupt end to your session.

Personal Preference

Some people have greater tolerance for heat than others. This means some people will feel uncomfortable or lightheaded after a short time in hot water. And, others can tolerate much longer sessions. Are you a heat-sensitive individual? Or, do you prefer long relaxing sessions? You can adjust your time in the hot tub depending on your personal preference.

The 15-30 minute duration works well for most adults. However, children and the elderly are more susceptible to temperature extremes and therefore should limit their session. Elderly people will benefit from reducing the water temperature from 100-102°F to 90-95°F. Children should also spend less time in the tub and use reduced temperatures – more on children below.


It is inadvisable to consume alcohol when using a hot tub. Alcohol triggers dehydration. An effect compounded by the heat of the warm water. And, it impairs judgment. This means you may not recognize the warning signs of becoming overheated or dehydrated.

People consuming alcohol run an increased risk of spending too long in the hot water and suffering the consequences. If you intend to drink alcohol you should pay particular attention to the duration of your session in a hot tub.



Hydration plays a key role in your ability to use a hot tub safely. You should ensure you are properly hydrated at all times when resting in the warm water. Hot tubs heat the body and trigger a sweat. This results in the loss of fluids. All these fluids need to be replaced to prevent dehydration. The best way to stay hydrated is to drink water before entering the hot tub, sip water while inside, and continue to drink water when you get out.

While these side effects only occur in extreme situations it is important you limit the length of your stay in the tub and listen to your body for signs of discomfort and overheating.
