Accurate temperature control is an important element of hot stone massage. For the safety and comfort of your clients, it’s important to make sure the hot stones are not hot enough to burn you or your client. Here are some tips on regulating the temperature of your hot stones.
A massage stone heater is specifically designed to maintain the proper temperature for hot stone massage, although other heating units may also work. The heating unit that you use to heat your stones must be able to maintain a constant temperature. A removable heating unit makes it easier to clean. You must heat your stones in water. Microwaves, hot plates, heating pads, and ovens are not safe options for heating your stones.
Place a white towel or rubber shelf liner on the bottom of the heating unit to make the stones easier to see and to prevent the stones from clanking against the bottom as you scoop them out or place them back inside.
Testing the Stone Temperature
Test out your stones and heating unit BEFORE using them with a client. To avoid delays in a treatment session, pay attention to how long it takes for the massage stones to reach the correct temperature. Give the stones adequate time to heat up before your client arrives.
Use a calibrated thermometer to gauge the temperature of the water. The optimum temperature is between 110 and 140 degrees Fahrenheit. Most heating units cycle on and off to maintain the set temperature. If the heating unit is set at a fixed temperature (with no temperature controls) and the water is hotter than normal, you may need to add more water to the heating unit. The less water that is in the heater, the hotter it will get.
The temperature of the stones should be comfortable enough to hold the stones in your hand for 5 full seconds without burning yourself. If the stone is too hot for you, it is too hot for your client. Never use a hot stone on a client before testing the temperature on your own skin first.
After placing stones back in the heater, let the stones reheat for at least 3-4 minutes before reusing them. Test the temperature of each stone on your own skin before use.
