What is important to know about the temperature in a hot tub?

Making Sure Your Spa Water Isn't Too Hot

Although hot tubs and home spas provide the perfect setting for relaxation, they can become very dangerous systems if general rules are not followed accordingly. One of the most important rules you need to follow is the temperature of the water in your tub. Water temperatures that exceed a certain level can potentially become dangerous to individuals using the tub, so a hot tub thermometer is always recommended.

The water temperature in your hot tub or spa should not, at any point in time, exceed 104-degrees Fahrenheit or 40-degrees Celsius. Immersion in water above these temperatures, especially for prolonged amounts of time, can lead to a variety of heat-related illnesses such as stroke, heart attack, nausea and brain damage. Worst case scenario, these temperatures can result in death.

It is important to recognize special considerations when setting the temperature of your hot tub. Children do not adapt to heat as well as adults do. That said, if children are going to be in the hot tub, the temperature should be lowered at least a couple of degrees in order to ensure their safety.

In addition, it is important to recognize the dangers involved with pregnant women. For the most part, pregnant women should avoid hot tubs throughout their pregnancy. The heat from the water (even if it is lower than what is recommended) can potentially harm the fetus. This can ultimately lead to birth defects or possibly even miscarriage. Should the female decide to go against recommendations and enter a hot tub regardless, the temperature of the water should not be greater then 100-degrees Fahrenheit and she should limit her exposure to 15 minutes or less.

Generally, 102-degrees Fahrenheit seems to be accommodating to all bathers and is not considered a health risk. Depending on the individual, some bathers prefer the effects of warmer temperatures. Use your own judgment when it comes to the temperature and use common sense. If studies prove that temperatures higher than 104 degrees Fahrenheit put you at risk, it may be best to follow their recommendations.

Ultimately it is your decision; make it wisely. The choices you make will have a great impact on your health and the health of all individuals using your spa.

The Harmful Results from Hot Tub Water that is too Hot

The question "can you really cook your brain?" is a difficult question to answer because it depends on each specific situation. If you're speaking literally, then the answer is no. It is impossible to completely cook your brain, just from using a hot tub, but there are a few minor exceptions.

Children's bodies are more sensitive to extreme temperatures than adults, and therefore have a different reaction when exposed to high temperatures. Small children should not be in a hot tub to begin with, but if they are for some reason, they are at risk of damaging their brain and other parts of their body. When a child's head is immersed underwater, the heat that is absorbed can greatly damage the brain. Because children are already susceptible to risk in a hot tub, it will not take long for injury to occur. A good rule of thumb is to keep small children out of a hot tub altogether. Older children can use a hot tub but only for short periods of time -10 minutes maximum - and should never completely immerse their head underwater.

The other exception is related to pregnant women. During pregnancy, women are advised to stay out of hot tubs because of the effects of hot water on the fetus. If a pregnant woman immerses herself in water as hot as what is usually found in a hot tub, she puts her baby at risk of severe brain damage. The hot water will cause the woman's body temperature to rise and the stomach (since it's underwater) will literally become like an oven to the baby. When it comes to pregnancy, it's best to avoid hot tubs and spas at all costs.

So back to the question "can you really cook your brain?" It all depends on what you consider cooking the brain. Burning the brain and severely damaging it is very possible, especially for unborn babies and small children. It would be difficult for an adult to cook their brain in a hot tub unless they purposely raised the temperatures to an extremely high degree and then intentionally immersed their head underneath the water for a long period of time. Can you damage your brain? Yes.

Use caution and common sense when operating a hot tub. In order to decrease the likeliness of brain damage associated with hot tubs, a;lways use a hot tub thermometer to make sure the temperature of the water does not exceed the optimum level recommended by doctors.
