Chlorine Rash And Swimmer’s Itch: Cause, Treatment And Prevention

Chlorine Rash And Swimmer’s Itch Cause, Treatment And Prevention

Both the swimmer’s itch and chlorine rash are swimming-related rashes. A swimmer’s itch is due to the microscopic parasites that dwell in freshwater, whereas a chlorine rash is a reaction of your body because of exposure to chlorine in the water.

In a swimmer’s itch, the parasites are from the snails which are present in the water. When you come in contact with them, the parasites can enter your skin. It can cause rashes that look like small pimples. Medically, this condition is known as ‘cercarial dermatitis.’

Knowing the difference between a swimmer’s itch and a chlorine rash depends on where you are swimming. Freshwater doesn’t have chlorine, unlike the swimming pools. If a pool is clean and well-maintained, it contains the right amount of chlorine, preventing the growth of parasites.

Meanwhile, you will be more likely to experience a swimmer’s itch when you swim in salt or freshwater. This is especially true when you swim in the shallow water by the shoreline.

This article will learn the causes of both the chlorine rash and the swimmer’s itch. Apart from the causes, you will learn the signs, symptoms, treatment, and prevention. 

Understanding Chlorine Rash

Chlorine Rash And Swimmer’s Itch Cause, Treatment And Prevention

Chlorine is a chemical that pool owners use to remove the bacteria in the water. With this, the pool becomes a safe environment to swim and enjoy. Because of its powerful disinfectant features, it has been currently added to various cleaning solutions.

Indeed, chlorine has multiple benefits. However, frequent exposure of swimmers to chlorine at the pool can cause several negative effects. This element can cause dryness and irritation of the skin. This is true even if you have regularly been swimming and haven’t experienced skin problems in the past.

If you experienced a rash after swimming, is it not automatically that you are allergic to chlorine. You might be sensitive to it. Luckily, there are ways on how you can treat chlorine rash without avoiding swimming early on.

Symptoms of Chlorine Rash

Chlorine rash can make the skin itch after swimming. The common symptoms are the following:

  • Crusting or scaling
  • Red and itchy rash
  • Hives or small bumps
  • Tender or swollen skin
  • Skin that can bleed or crack after frequent contact with chlorine
  • Blisters or sores

Your eyes can be irritated from chlorine exposure. Sometimes, it can affect the respiratory tract too. When you are exposed to chlorine, you might notice that you sneeze and cough frequently.

Cause of the Chlorine Rash

Not all swimmers experience a chlorine rash. People can often experience this when they repeatedly get themselves exposed to chlorine. The immune system may tag chlorine as a foreign invader similar to a virus or bacteria. As such, the skin becomes irritated and inflamed. Chlorine can strip off the natural oils from the skin, which causes it to dry.

Even if you rinse or bathe yourself after chlorine exposure, some residues can remain in the skin. Indeed, continued exposure can lead to prolonged irritation and agony. With this, those at risk for chlorine reactions are the swimmers, professional cleaners, and lifeguards.

Sometimes, the caretaker of the pool may add too much chlorine to the pool. Excessive chlorine in the water can be irritating to the skin.

Treatment of Chlorine Rash

You can solve a chlorine rash by buying over-the-counter (OTC) medicines. Examples of these are corticosteroid creams like hydrocortisone. However, most medical professionals don’t recommend hydrocortisone cream on the face. The skin on the face is thin, and the cream can irritate the eyes and mouth.

If you experience hives, you can take medications or apply diphenhydramine cream like Benadryl on the skin. You can also buy lotions or body washes that can remove chlorine and soothe the skin.

Avoid scented lotions, which can add irritation to the skin caused by chlorine. The topical applications mentioned above will help reduce the incidence of a chlorine rash. This can help you swim comfortably and enjoy the day.

When to Consult a Doctor

If you are experiencing a severe allergic reaction such as hives or difficulty breathing, you must consult a doctor immediately. An allergist will diagnose you and help treat the problems which are related to a chlorine rash. This is true especially for those who have a chlorine rash but still wanted to swim and continue their exposure.

Moreover, if your chlorine rash is not healed by the OTC medications, you must consult a medical specialist. For example, an allergist can give you stronger treatments, like the prescribed corticosteroid creams.

Understanding Swimmer’s Itch

Chlorine Rash And Swimmer’s Itch Cause, Treatment And Prevention

Cercarial dermatitis is due to a parasitic worm that clings to your skin. Don’t worry, and this parasite doesn’t live in humans. It accidentally attaches to the skin while searching for an animal host. Its normal life cycle is from the water animal to snail and vice versa. You happen to be present and swimming in the water when the parasite is looking for its natural host.

The worm can infect the waterfowl’s blood and all the animals that live near the water. Then, the animals or birds can pass the eggs of the parasites into the water by their feces. As soon as the parasite’s eggs hatch in the water, the larvae can swim around and find their second host, who is the snail. After the parasite infects the snail, it will develop in it. The snail will excrete other parasitic larvae in the water. Such larvae are known as the cercariae, which swim around in the water looking for water animals. Then, the cycle continues.

These larvae can live for 24 hours while hunting for a host to live and continue the cycle. Thus, if you swim in infected water, some of the worms can land on your skin.

Outlook for Swimmer’s Itch

During summer, a swimmer’s itch is a common ailment in different parts of the world. The rash can clear up on its own without experiencing further complications. As soon as the rash is gone, you can have a pigmented spot where the pimple was for some weeks.

Determining how long can the water remain infective will depend on several factors:

  • There are hundreds of species that can be the parasite’s host
  • There are various parasites species with their attributes
  • Waterfowl are migratory, and they can pick up the parasite in any part of the world
  • The life cycle of the parasite will depend on the infection the snails or birds present
  • The sunlight and temperature play a major role in the life cycle of the parasite.

According to a study in 2015, more research is needed to determine the control measures. For example, it is advised to know more of the particular species involved to determine its control efforts. Moreover, a warming climate can tend to increase the incidence of swimmer’s rash among us.

Indeed, control efforts are not an easy task. It is possible to cure the waterfowl using an anti-worm drug to decrease the parasite population. This will need us to capture, treat, and release the birds individually. Reducing the waterbird population in recreational areas is a hard task. It is also possible to use snail or poison. However, this can bring damaging effects on other animals.

Overall, it can be difficult to control the prevalence of the parasite in certain bodies of water. But take note that a swimmer’s itch is not a serious medical condition.

People at Risk of Swimmer’s Itch

You can be at risk of experiencing the swimmer’s itch whenever you swim in an infested freshwater. If you put in shallow water near the shoreline can put your life at a higher risk since the larvae can be present.

In addition, children can be at risk since they play and wade at the shore. If you have experienced a swimmer’s itch before, you will likely experience a worse reaction the next time you get exposed to it.

It is important to remember that chlorinated and well-maintained pools are safe to swim in. This won’t pose the danger of catching the swimmer’s itch on you. Moreover, a swimmer’s itch is not contagious.

Diagnosis of Swimmer’s Itch

Cercarial dermatitis can be challenging to distinguish from other skin reactions like bacterial infections, jellyfish stings, poison ivy, and insect bites. Your doctors might ask questions to aid in diagnosis. Some of the questions include:

  • When did the rash begin?
  • Have you been wading or swimming recently in salt or freshwater?
  • Are there any other people swimming with a rash?

Your doctor might ask about your medical history. Thus, you must disclose any allergies, medications, or supplements that you have. If the itching becomes severe, the doctor will prescribe stronger medicines for you.

Treatment of Swimmer’s Itch

You can rely on home treatments to calm the itch that you have from a swimmer’s rash. Some of the remedies available are the following:

  • Cold compress
  • Corticosteroid cream
  • Anti-itch cream or lotion
  • Baths with Epsom salts, baking soda, or colloidal oatmeal
  • Baking soda paste

When you think about swimming in freshwater, avoid wading in places where you know swimmers who experienced a swimmer’s itch.

How to Prevent a Chlorine Rash and Swimmer’s Itch
