All About Finding the Ideal Hot Tub Temperature for a Normal Spa, for Kids, for Pregnancy, for Seniors, and More...

Having the most ideal hot tub temperature is an essential element to get correct if you want to get the most out of your spa.

Perhaps nothing beats relaxing in a hot tub to cap a day of hard work in the office or at home, but safety must be the foremost consideration and part of it is setting the right hot tub temperature.

Just sitting comfortably in a spa right in your own home can recharge you and get your ready for another grind the following day. Here are some safety guides you need to consider when setting the temperature for your hot tub or Jacuzzi.

  • Recommended Settings

    Ideally, 104 degrees F is the ideal hot tub temperature. Any setting higher than that may be considered a health risk as it can make the body temperature rise to a level that is beyond what the body can safely tolerate.

    Because of this official recommendation, most hot tub manufacturers have put in place some form of precaution by limiting the heat settings in their models in such a way that it cannot be made to exceed the recommended 104 degrees F by too much. Some of them even suggest maintaining a heat limit that is a couple of degrees below 104 degrees F as this is what most hot tub users prefer and find satisfactory.

    Based on individual user preference, the warmth that hot tubs provide can be easily adjusted. This can result to people exceeding the 104 degrees F recommended limit. There are cases when the thermostat or sensors in hot tubs malfunction that causes it to misread the actual Jacuzzi temperature which without proper safety controls can reach dangerous levels of up to 110 degrees F.

    Prolonged stay under such conditions, regardless of what it feels like, is extremely dangerous and easily breaches the threshold of physical safety.

  • Personal Tolerance Levels

    Not everyone has the normal internal body temperature of 98.6 degrees F. Because of this, some are able to tolerate a few degrees higher or lower than the average. What other people may consider as too hot or too cold may actually be comfortable for some people.

  • Age and Overall Physical Condition

    Generally, adults can tolerate a higher hot tub temperature more than children who find it more difficult to adapt to temperature changes. A lower setting should therefore be maintained for kids.

    A high warmth setting is also bad for pregnancy, not necessarily for the woman, but rather for the baby she is carrying.

    Because the recommended 104 degrees F setting can increase blood pressure, people with hypertension and heart conditions should maintain cooler settings to avoid getting a heart attack or a stroke that may be fatal.

    Obese people generally have a more difficult time cooling themselves and may also be exposed to health risks with very hot water. People under medication or drugs, or have eaten foods that induce a relatively higher blood pressure must also stay in hot tubs at lower settings.

  • Number of People

    The more people are in a hot tub at the same time, the cooler the water becomes. This is why it may be necessary to adjust the thermostat to a higher setting when more people are in the tub. The hot tub temperature, however, should be kept lower when fewer people are using it.
