Suitable products and services for foot massage devices
For healthy adults, a foot spa is safe if three things are right: the temperature is below about 38 degrees Celsius, the duration is under 20 minutes, and the device is clean. It becomes risky for people with diabetes who have impaired sensation, open wounds, acute thrombosis, and poorly cleaned devices. Here are the reasons and the rules.
The three real risks
A scald that nobody notices. Those who can no longer reliably feel the temperature in their feet, for example due to nerve damage from diabetes, can suffer burns without realizing it. In this situation, wounds on the feet heal slowly, and this can quickly become a bigger problem. This is the most common serious complication.

Germs in stagnant water. Warm water in hoses and nozzles provides a breeding ground for bacteria. Those who don't empty and dry their device after each use risk developing athlete's foot and other skin infections, especially if there are small injuries between the toes.
Electricity by the water. A device with a damaged cable should not be used near a body of water. This sounds obvious, but it's the reason why these devices undergo testing and should not be used after a fall.
For whom it is not suitable
- Impaired temperature perception on the feet, regardless of the reason.
- Open sores, wounds, eczema, fungal infections. Warm water softens the skin and spreads germs.
- Acute thrombosis or suspected thrombosis. Heat dilates the blood vessels, which is undesirable here.
- Acute phlebitis. Warm and reddened means: do not warm.
- Pronounced varicose veins. Not forbidden, but heat often intensifies the feeling of heaviness. See Is it okay to massage if you have varicose veins?.
- Pregnancy. Hot baths should be avoided; lukewarm baths are usually unproblematic after consultation. See Foot massager during pregnancy.
The right temperature
Thirty-five to thirty-eight degrees Celsius is the usual range. This feels pleasantly warm, not hot. If you're unsure of the temperature, measure it with a thermometer or have someone else put their hand in. The elbow is a better place to test than the hand because it's more sensitive.
The same caution applies to heat as to armchairs with a heating function: heat relaxes, but it also masks pain, which would be a warning.

Hygiene that is truly necessary
- After each use, drain the water, wipe out the basin, and leave it open to dry.
- Regularly rinse nozzles and hoses; for devices with a circulation pump, descale according to the instructions.
- Do not use any additives that foam or leave an oily residue unless explicitly permitted by the manufacturer. Oil will build up in pipes.
- If you have athlete's foot in your family, don't share any equipment without disinfecting it in between.
What to stop at
Dizziness, palpitations, a persistent tingling sensation, or skin redness that remains after drying. After bathing, dry your feet thoroughly, especially between the toes, and examine your skin. Those who bathe daily should check their feet daily.

Briefly summarized
- Safe for healthy adults at temperatures below 38 degrees, for less than 20 minutes, and with a clean device.
- The greatest risk is scalding in people with impaired sensation, such as those with diabetes.
- Stagnant warm water is a breeding ground for bacteria, therefore empty and dry after each use.
- Do not use on open wounds, in cases of acute thrombosis and acute phlebitis.
- After the bath, dry your feet and look at the skin, especially between the toes.
