What Happens If You Stay In a Hot Tub too Long?

Hot tubs are a fun way to relax and unwind, but people often wonder what will happen if you stay in a hot tub too long. While staying in a hot tub for a short while can provide relaxation and health benefits, staying in a hot tub for too long can create health problems that can even be life-threatening.

It is recommended by experts that one should not stay in a hot tub for more than 20-30 minutes as the temperature of the water in the hot tub is often in the range of 100-104 degrees F. Such a high temperature can be harmful to a person resulting in nausea, dizziness, fever, and in extreme cases even death.

What happens to your body when you stay in a hot tub?

The core temperature of the human body is 98.6 degrees F, and when the body faces temperatures higher than the core temperature, the body’s core temperature also rises. Higher core temperature can result in a feverish state where a person can feel dizzy and nauseous. As the heat transfers from your body to the water of the hot tub, your body’s core temperature also rises. The higher temperature can also cause low blood pressure, and the heart has to work harder to pump blood through the body.

Sitting in a hot tub is also a cause of dehydration as a person does not realize they are dehydrated because they are sitting in the water. The body starts to sweat to bring down the core temperature, and this can further aggravate the dehydrated state of the body.

Symptoms of an extended stay in a hot tub

How do you know that you have stayed too long in the hot tub and you should get out? If you feel any of the below symptoms, then it’s time to get out of the hot tub.

  • Dizziness
  • Fever
  • Confusion
  • Breathlessness
  • Skin irritation or burning sensation
  • Vomiting
  • Dehydration

How to Make Sure you Stay in a Hot Tub for a Safe Duration

If you are planning to spend some time in a hot tub, make sure you do it in the company of another person who can help you in case you feel dizzy or lightheaded. You can keep the hot tub on a timer so that when 30-45 minutes have elapsed, the hot tub should start lowering the temperature.

You can also sit in the hot tub for small durations and keep getting out whether to drink water or to interact with your friends. Also, you can try sitting in the hot tub till your waist or chest area so that your body can dissipate the heat better. Half sitting in the hot tub will allow your body to regulate the temperature better so that your body does not overheat. There are hot tubs with built-in seats and cushions that will enable you to sit up and keep your torso out of the hot tub.

Things to Keep In Mind

If you have any medical history or health issues that need medical attention, make sure you consult your physician before sitting in the hot tub. People who have problems associated with blood pressure or heart problems should practice caution while sitting in a hot tub.

Pregnant women and children should also avoid sitting in a hot tub as the high temperature of the water can be detrimental to their health. If you are facing skin allergies or seasonal allergies, talk to your physician if a hot tub session would be right for you as the heat can exacerbate certain skin conditions.


As you have read above, staying in a hot tub for too long can be harmful to your health. Practice due caution when soaking in a hot tub and make sure you are always accompanied by someone who can help you if you feel dizzy or nauseous. Keeping a timer next to the hot tub can remind you when to get out of the hot tub. A timed hot tub session will prevent your body from heating up too much.

Also, avoid letting children below five years of age soak in the hot tub as their bodies cannot handle the high temperature of the water in the hot tub. Another good habit is to stay hydrated while you are in the hot tub as the water can quickly dehydrate your body, and you might not even realize it as you are sitting in the water. Remember, in moderation, a hot tub soak can do wonders for your health, and you must practice caution if you want to stay healthy.
