A soothing dip in a spa may appear to be the perfect way to invest a cool summer night. But in rare circumstances, danger may lurk beneath those soothing jets: Spa use has been associated with various kinds infections and injuries. Listed below are five methods for you to get hurt in a spa.

Spa lung

One unusual ailment associated with Jacuzzis is «spa lung,» a lung disease due to bacteria that may thrive in tepid to warm water. The bacteria, referred to as Mycobacterium avium complex (MAC), have a particular outer layer which allows them to stick to surfaces, instead of being washed away by water (as much other bacteria are). If a spa is contaminated with MAC, the bacteria can latch onto air bubbles and be aerosolized when the bubbles reach the top, according to a 2017 paper on the problem.

When people breath in the bacteria, they might develop «granulomas,» or small regions of inflammation, within their lungs. People who have spa lung may experience flu-like symptoms, including cough, trouble breathing, fatigue and fever.

About 70 cases of spa lung have already been reported in the medical literature, based on the 2017 paper. Most cases are linked with indoor hot tubs, where there is less ventilation. A lot of people see improvement within their symptoms if they simply stop moving in hot tubs, but some individuals may need treatment with corticosteroids or antibiotics, according to a 2006 study from the Mayo Clinic.

Spa rash

In the event that you use in itchy spots after utilizing a spa, you may have «spa rash.» It’s one of the most common illnesses associated with hot tubs, based on the Centers for Disease Control and Prevention (CDC). Contamination causes The rash with the bacterium Pseudomonas aeruginosa, and medical indications include itchy skin that risk turning right into a bumpy red rash or pus-filled blisters surrounding hair roots. The infection is often worse in the region under someone’s swimsuit, as the suit might keep contaminated water in touch with the skin, the CDC says.

The chance of catching this kind of infection in a spa is increased since the high water temperatures could cause disinfectants, such as for example chlorine, to breakdown faster, based on the CDC.

To avoid spa rash, the CDC recommends showering with soap and cleaning your swimsuit after getting away from the water. People can ask the spa operator if the disinfectant and pH levels are checked at least twice a day. The rash clears up without treatment usually.

Legionella infection

Steamy hot tubs may also pose a threat of Legionnaires’ disease, a kind of pneumonia due to Legionella bacteria. These bacteria are located in water naturally, and hot tubs that are not disinfected properly may become contaminated with Legionella, based on the CDC. People become infected if they breathe mist or steam from the contaminated tub, the CDC says. Making sure hot tubs have the proper degrees of disinfectants is vital to stopping Legionella infection, the agency says.


In very rare circumstances, engaging in a spa can raise the threat of urinary system infections (UTIs). At fault in these infections is Pseudomonas aeruginosa again, that may cause UTIs. (This bacterium also causes spa rash.) In the 1980s, researchers in Denver reported three cases of UTIs associated with spa use. In every three cases, the patients developed UTIs within 48 hours of using the tubs. Tests showed the infections were due to P. aeruginosa, that was within the tubs also. It is possible that water jets could have propelled this organism in to the patients’ urethras, the researchers said.

In ’09 2009, researchers in NY reported the case of a 38-year-old man who developed a potentially life-threatening condition called urosepsis after being in a spa. Urosepsis occurs when the bacteria that cause UTIs (in cases like this, P.aeruginosa) find their way right into a person’s bloodstream. The researchers discovered the man’s spa as the foundation of his infection. The individual reported having sex along with his wife in the spa, which likely increased his threat of infection, the researchers said.

Still, that is uncommon. A 2000 study of risk factors for urinary system infections among young women found no difference in usage of hot tubs between those that had recurrent UTIs and the ones who didn’t.

Allergic attack

Chemicals used to completely clean and disinfect hot tubs could cause allergic reactions in a few people. Specifically, a chemical called potassium peroxymonosulfate (PPMS), which can be used to remove organic contaminates from the water (in an activity called «oxidation»), has been associated with allergies.

This year 2010, several dermatologists in Ohio asked all their patients with widespread rashes if indeed they used hot tubs. During the period of a year, they found six patients who were allergic to PPMS and who had also used this chemical to take care of their hot tubs. All the patients were men, and most of them saw improvement within their symptoms if they avoided hot tubs.
