Have you ever been in a hot tub or public swimming pool and found red, itchy blisters all over your body a couple of days later? They're like pimples, but they're itchier. If that's the case for you, you may have a skin condition called Hot Tub Folliculitis . While the name may sound like a big deal, it's not that serious. But it's important to know a little about it. Let's talk about it in more detail, shall we?
So, what is Hot Tub Folliculitis?
Simply put, this is an infection of the hair follicles , the places where hairs grow on our skin. Imagine, we have tiny hairs on our bodies, and each hair starts from a small sac inside the skin. That's where this infection occurs.
The main cause of this is a type of bacteria called `Pseudomonas aeruginosa` . This bacteria loves to live in warm, moist environments. So, this bacteria can easily spread in places like hot tubs, swimming pools, and water parks that are not properly cleaned. If you stay in such places for a long time, this bacteria can enter your hair follicles and cause an infection.
Who is most likely to develop this?
In fact, anyone who bathes in water that contains the bacteria Pseudomonas aeruginosa can develop hot tub folliculitis. However, some studies have shown that girls and women are slightly more likely to develop the condition. The exact reason for this is not clear, but it may be due to factors such as the way you wear your swimsuit and certain hair removal methods.
What does Hot Tub Folliculitis look like on the body?
The main symptom is red, itchy blisters that spread all over the skin. They look like lots of little pimples. These blisters usually appear in areas where you've been in a hot tub, meaning anywhere that's been exposed to water. They can even appear under your swimsuit. These blisters are most often seen:
- On the face
- In the chest
- In the hands
- In the buttocks area
- In the genital area
- On the legs
Sometimes these blisters can develop into pus-filled blisters (pustules) . This means that the blisters have a yellowish-greenish liquid (pus) at the top. Very rarely, these blisters can also appear on the palms of your hands and soles of your feet.
Are there other names for this?
Yes, sometimes doctors call this condition `pseudomonas folliculitis` , because it is caused by a bacteria called `Pseudomonas`. It is also commonly called `hot tub rash`.
How common is this condition?
In fact, it's more common than you might think . This infection is most common in warm, humid environments like public and private swimming pools, water parks, and flotation tanks. Researchers say that at any given time, about two-thirds of hot tubs and swimming pools can harbor the bacteria `Pseudomonas aeruginosa`! Imagine that!
What is the exact reason for this?
As we mentioned earlier, the main cause of this is spending too much time in a warm, humid environment (especially a hot tub) that contains the bacteria `Pseudomonas aeruginosa` . This bacteria can enter the hair follicles on your skin and cause an infection.
What are the symptoms?
The main and most common symptom of hot tub folliculitis is an itchy, red, blistered rash . This usually appears a few days after exposure to a hot tub. These blisters can sometimes cause the area to become red and swollen.
In addition to these skin symptoms, some people may experience other symptoms, but not everyone will experience them.
- Diarrhea
- Eye pain
- Fever
- Headache
- Nausea and vomiting
- Sore throat
Remember, not everyone gets these additional symptoms. The main ones are itching and blistering of the skin.
Is Hot Tub Folliculitis Contagious?
Here's a question that many people ask. Hot Tub Folliculitis is not directly transmitted from one person to another . That means you won't get it from touching or being with someone who has the condition.
But, imagine that you and a few of your friends are in the same hot tub. If that bacteria is in that hot tub, you could all be exposed to that bacteria at the same time and all of you could develop this hot tub folliculitis. It's because of the water that has the bacteria, not because it's spread from person to person. Got it?
How does a doctor recognize this?
Most of the time, your doctor or midwife can tell if it's hot tub folliculitis from the details you give them (i.e., whether you've been in a hot tub or swimming pool recently) and by examining your skin.
It usually does not require special laboratory tests. The diagnosis is made based on the nature of the blisters on your skin and the details of your exposure to the water.
Does this require treatment?
The good news is that most of the time, hot tub folliculitis doesn't require any special treatment . The condition usually clears up on its own within a week or two.
However, if these blisters on your skin are getting bigger and bigger, the itching is severe, or if they don't get better after two weeks, you should definitely see your doctor.
What treatments can be done at home?
If your skin itching and redness are a bit severe, you may find relief with the following:
- To reduce itching and redness, you can use an ointment such as hydrocortisone skin cream, which you can buy at the pharmacy . These can be purchased over-the-counter without a doctor's prescription.
- You can also use antibacterial ointments to prevent bacterial infections , as scratching can damage the skin and lead to other bacterial infections.
Also, avoid scratching as much as possible. Scratching can damage the skin, make the condition worse, and may even cause scarring.
Can this cause complications?
Complications from hot tub folliculitis are rare . Sometimes, scratching or popping the blisters can cause skin damage, which can lead to another infection.
Very rarely, a pus-filled blister (pustule) can develop into a large abscess , which requires immediate medical attention.
Some people may also notice a change in skin color (darkening) in the areas where the blisters were after the hot tub folliculitis has healed. However, this is also very rare.
How long does it take to heal?
For most people, symptoms subside completely within a week or two . Using anti-itch creams can help many people manage their symptoms.
How do you know if a hot tub is safe?
Swimming pools and hot tubs need to be maintained to ensure they are safe for the health of those who use them. This means using the right amount of chemicals (such as chlorine ) to keep them clean and control bacterial growth.
However, it's hard to tell just by looking at a hot tub whether it's clean or safe. If possible, ask the person who maintains the hot tub how often they clean it and check the water quality. A hot tub that is maintained daily and checked for water quality is generally considered safe .
How can this be prevented from happening?
You may not always know if the hot tub you're using has Pseudomonas aeruginosa bacteria. However, you can take a few steps to protect yourself:
- Avoid removing body hair (shaving, waxing, using hair removal creams, etc.) immediately before getting into a hot tub, as this can cause minor abrasions and wounds on the skin, which can easily introduce bacteria.
- As soon as you get out of the hot tub, take off your bathing suit, wash your body thoroughly, and take a shower .
- Wash and dry your swimsuit thoroughly before wearing it again .
What should we expect if this situation arises?
Your symptoms should improve within a week or two . If they don't, be sure to see your doctor.
When should I see a doctor?
If the rash on your skin is getting worse, the itching is severe, it doesn't get better after a few days, or if you have these blisters along with symptoms like fever, nausea, and vomiting , you should definitely see a doctor immediately.
Sometimes, if these blisters become severely infected, you may need to take antibiotics .
How can I prevent this from happening to my hot tub?
If you or someone else develops hot tub folliculitis while using a hot tub or swimming pool in your home, be sure to contact a professional who is experienced in hot tubs or swimming pools. To prevent re-infection, the tub or pool should be thoroughly cleaned . The professional will also advise you on proper maintenance practices to prevent bacterial growth.
So, the last things to remember
Hot Tub Folliculitis is an infection of the hair follicles on our skin caused by the bacteria Pseudomonas aeruginosa, which is often found in hot tubs and swimming pools.
This is usually not a serious condition and will heal on its own within a week or two.
However, if the symptoms are severe, or if there are other symptoms such as fever, it is best to see a doctor immediately.
Also, when using hot tubs and swimming pools, paying attention to their cleanliness and following the safety measures we discussed earlier can go a long way in preventing this condition from occurring. So, be careful!
