Let’s face it—pools aren’t the cleanest places when you really think about it. Even though many of us don’t love swimming in a pool full of chemicals, like chlorine, it’s probably better than letting nature take its course. Chlorine is essential for keeping the water sanitized, but that doesn’t mean we have to enjoy the harsh smell or the effects it has on our skin.
If you’re swimming outdoors, your main skin concern is likely the sun’s UV rays and the risk of a sunburn. That’s completely understandable. But even with the best sunscreen, after a swim, you might notice that your skin feels dry, tight, and flaky. This could be due to chlorine, which some people have a more intense reaction to, even leading to a rash. Here's what to know about chlorine rashes, how to spot them, and how to treat them.
What exactly is a chlorine rash?
First of all: The American College of Allergy, Asthma & Immunology (ACAAI) clarifies that a chlorine-induced rash does not indicate an allergy to the substance.
This rash is actually “irritant dermatitis,” which resembles a chemical burn and results from heightened sensitivity to chlorine. Chlorine is a natural irritant, which is why your skin feels so tight and dry after swimming. Additionally, if you already suffer from a form of dermatitis, chlorine may exacerbate it, according to the ACAAI.
What are the signs of a chlorine rash?
Generally, a chlorine rash presents with one or more of these symptoms, as noted by the ACAAI:
Redness, tenderness, swelling, or itching at the area of contact
Rashes or skin lesions
Scales or crust forming on the skin
Hives
How can you treat a chlorine rash?
The ACAAI suggests handling a chlorine rash in much the same way as other skin irritations: by “washing the affected area with clean water to help remove any lingering traces of the irritant”—in this case, pool water.
For more severe reactions, if basic washing doesn’t help, it’s wise to consult with your doctor or allergist to rule out an unrelated allergic reaction. Depending on the severity, your doctor may recommend a corticosteroid cream (and it’s important to follow the prescribed usage to avoid overuse). If hives appear, they may suggest an antihistamine, such as Benadryl.
Another good reason to rinse off with a quick shower after leaving a pool.
