Chlorine Rash

Chlorine rash is the common name for a dermatologic reaction to chlorine. This article will discuss the symptoms, diagnosis, and treatments of Chlorine rash. You can also find various pictures of how chlorine rash presents itself.


Chlorine intolerance vs chlorine allergy

A reaction to chlorine can present itself as a rash or red itchy skin. It may at times even appear with bumps. Rather than an allergic reaction, this is considered irritant dermatitis or a chemical burn. Another intolerance or reaction to chlorine can present itself as dry skin. An allergy to chlorine is usually presented as respiratory issues such as asthma.  (1,2)

The following are specific examples of symptoms from chlorine allergy. These issues are not ever present in the case of intolerance or sensitivity. If you note these reactions please seek medical attention. :

  • Breathing or respiratory issues.
  • Swelling noted in the lips, tongue, or face
  • Dizziness
  • Syncope

Chlorine rash cause and prevention:

Most Chlorine rashes are caused by hot tubs or swimming pools. In rare cases, the chlorine may be an additive in cleaners or insecticides. (1,2)
The cause may simply be too much chlorine in a pool or hot tub which causes the “burn” on the skin.

Often times a rash is caused by a bacteria called pseudomonas aeruginosa. This occurs due to poor pool maintance resulting in a low amount of chlorine being used in a pool or hot tub. Some other causes of this type of infection are, extended time in pools or hot tubs as well as too many people in the swimming area. (2, 4)

Ways to prevent chlorine rash:

  • Ask pool or hot tub owners what the chlorine level is.
  • Take off swimsuit and wash with soap and warm water after leaving the pool or hot tub.
  • Wash your swimsuit after use in public swimming areas
  • Avoid use of public swimming areas
  • Check to be sure your swimming suite isn’t too tight.
  • You can buy pool strips to check the PH and chlorine levels. Here is a quick list of adequate
  • levels according to the CDC.
  • Pools should show 1-3 ppm (parts per million)
  • Hot tubs: 2-4 ppm
  • Ph:7.2-7.8 (2, 3, 4)

Chlorine Rash Symptoms:

A dermatological sensitivity to chlorine may present itself as one of the following:

  • Lesions or bumps on the skin surface.
  • Skin redness
  • Tenderness to the touch.
  • Inflammation
  • Itchy irritated skin
  • Hair follicles filled with pus
  • Crusty or dry skin.
  • The affected area may be where the swimsuit was covering the skin. (1,2, 8)

If untreated and an infection begins the following systemic symptoms may be noted:

  • Fever
  • Headache
  • Achy body
  • Weakness
  • Earache
  • Tenderness near lymph nodes
  • Red eyes (4, 8)

Diagnosis of Chlorine rash:

Diagnosis should be made by a doctor or an allergist. They will do a visual exam of the skin and ask you’re most recent activates. The rash usually occurs within 45 hours of chlorine contact. For this reason, your recent history of activities is very important.

It is  also important to receive medical attention if you are not certain where your rash came from. Chlorine rash could be mistaken for any of the following issues:

  • Bromide sensitivity (Bromide is often used instead of chlorine in pools and hot tubs)
  • Acne
  • Bug bites
  • Staph infection (1, 3, 4, 8)

Treatment

If a severe allergic reaction is considered, a trip to the emergency room is needed. In general, treatment is to support the symptoms noted. If the reaction is only on the surface of the skin and not causing major pain then the following are common treatments:

  • Wash the affected area well, preferably with hypoallergenic soap.
  • If hives are noted then an antihistamine may be needed.
  • Corticosteroids may be administered if there is a lot of inflammation of swelling noted. (2,3, 8)

There are also many home remedies that may be tried:

  • Warm or cold packs may help relieve pain and or itching.
  • Baths with corn starch can help sooth the itching.
  • Fresh aloe vera or even aloe vera gel can be applied directly to the affected area. (3)
