How Long Can You Stay in a Hot Tub?

A long relaxing soak in a steamy hot tub is just what the doctor ordered for reducing stress and relieving sore muscles. However, there are hot tub safety rules you should adhere to when enjoying this soothing spa treatment. One rule in particular addresses the recommended time in a hot tub before you may be at risk of overheating.

How Long Can You Stay in a Hot Tub?

The length of time you can safely spend in a hot tub is based on several factors, so it is difficult to determine a precise number that applies to everyone. Use the items below to estimate the time limit that is best for you.

Water Temperature

The temperature of the water in your hot tub is one of the biggest factors affecting the recommended time in a hot tub. The hotter the water, the less time you should spend soaking. When your internal body temperature gets too high, you can become quickly dehydrated and overheated, so as a rule of thumb, keep the hot tub temperature between 100 and 102 degrees. At this temperature, a healthy person will most likely be able to soak safely for about 15-30 minutes.

Submersion Level

The more of your body that is in the water, the faster your body temperature will rise. So if you are submerged up to your neck, you will not be able to stay in the water as long as if you just put your lower body in the water.

Individual Health

If you are pregnant or have a medical condition, particularly one relating to the heart or cardiovascular system, you should consult a doctor before getting into a hot tub.


Children under 12 should not get into a hot tub that is greater than 104 degrees. Lower than that is acceptable for approximately 15 minutes or less, but it is recommended that children keep their upper bodies out of the water as much as possible. Some hot tubs have higher seats for this purpose. Healthy adults are generally fine, but should be aware of the signs of overheating.

Signs of Overheating

The most important things to remember when it comes to hot tub safety rules are to stay hydrated and listen to your body. If you start to feel discomfort or notice any of the following signs, it is a good idea to get out of the hot tub right away.

  • Headache
  • Dizziness or Lightheadedness
  • Tingling Sensation
  • Change in Heart Rate
  • Weakness or Fatigue
  • Intense Sweating or Lack of Sweating

In more extreme cases, you may experience some of the following symptoms. If these symptoms are persistent or get worse after you have dried off, cooled down, and had some water, you should see a doctor or call 911.

  • Vomiting
  • Nausea
  • Redness or Burns on Your Skin
  • Blurred Vision
  • Fainting
  • Becoming Unable to Focus or Concentrate
  • Confusion
  • Rapid or Shallow Breathing

Are Hot Tubs Safe?

After reviewing the above hot tub safety rules, a healthy adult may possibly stay in a hot tub for as long as they do not experience symptoms. However, it is highly recommended that you take frequent breaks and drink plenty of water. It is a good idea to get out of the hot tub every 30 minutes to cool off and hydrate.

Benefits of Owning a Hot Tub

There are numerous benefits to owning a hot tub, from spending time with family and friends to improving physical health. Regular use of a hot tub can ease muscle pain and speed up recovery after a workout. It can alleviate stress on your joints and reduce pain from arthritis and inflammation, as well as improve blood flow and lower blood pressure. And of course, it is extremely relaxing and great for reducing stress and anxiety.
