It burns.
You know the feeling. Winter usually does the heavy lifting for flare-ups, thanks to dry air and central heating. But summer? It brings its own specific brand of misery. Shari Marchbein MD points out that atopic dermatitis doesn’t just hibernate in the warm months. Heat. Sweat. Seasonal pollen. The wrong sunscreen.
All of it adds up.
Sweating isn’t just gross. It’s chemical warfare against your skin. Susan Bard MD notes that perspiration contains zinc, copper, iron, nickel, even lead and cadmium. When that mixture dries on your epidermis, it leaves a crusty residue that screams irritation.
So how do you survive? Here is how to keep your skin from rebelling while everyone else is beach-combing.
Stop the Sweat Cycle
The most obvious fix? Stay cool. Daniel P Friedmann MD suggests avoiding extreme heat entirely. It’s hard. Try it anyway. Stick to the shade. Stay in air conditioning if the temps spike. Maybe add a humidifier if the AC makes the room feel like a desert.
Drink water. Seriously. Your internal thermometer matters. Wear light colors. Wear loose fabrics that wick moisture. If you run, do it in the dark. Early morning or late evening. The sun isn’t looking as hard then.
Sweat happens? Rinse off immediately. Cool shower. Do it fast. Don’t let the salt dry.
Mineral Sunscreens Only
Slapping on SPF is necessary. But most sunscreens hate eczema-prone skin.
Go physical. Or mineral. Avoid chemical filters that burn sensitive areas. Look for zinc oxide or titanium dioxide on the label. These sit on the skin rather than absorbing into it. They are generally less irritating and more moisturizing.
Some people get photoallergic reactions where sun + ingredient = dermatitis. If you suspect this, ask an allergist for a patch test. Find the villain. Ban the product.
Choosing the right protection is not optional. It prevents the burn.
Change Your Clothes. Now.
Damp clothes are a no-go. If your shirt sticks to your back because of sweat, swap it out. Immediately. Wet fabric against compromised skin triggers flare-ups faster than you think.
Dry is good. Damp is bad.
Filter the Air You Breathe
Pollen counts rise in summer. Joshua Zeichner MD warns that these particles can incite histamine release when you breathe them in, which manifests as itching.
Buy an air purifier. Preferably a HEPA filter with carbon. Zeichner notes more research is needed on air purifiers for eczema specifically but the theory holds. Clean air means less inflammation.
Check the Air Quality Index (AQI). If it is above 100, stay inside. Pollution worsens atopic dermatitis according to current data.
Indoors isn’t always safe either. Strong cleaners and heavy solvents pollute your home air. Use less.
Swim With Caution
Chlorine stings. Salt crusts. But swimming offers cardio without the excessive sweating of a run.
If you go in, rinse off immediately after you get out. Carry water if a shower isn’t nearby. Follow up with an emollient. Lock in the moisture that pool water tries to steal. Then reapply sunscreen. Protect the dry patches.
Wash Gently
Daily showers clear bacteria. They remove dust and old sweat. However recent studies suggest weekly bathing might offer the same clinical benefits as daily. It’s about quality not quantity.
Use mild soap. No dye. No fragrance. Lukewarm water only.
Do not scrub. No loofahs. Pat dry. Do not rub.
Apply moisturizer while your skin is still damp. This traps the water inside.
Feed the Barrier With Ceramides
Ceramides are lipids your skin needs naturally. When you’re dry they drop.
Put them back in. Marchbein recommends applying ceramide-heavy creams within 60 seconds of showering. It helps rebuild that protective wall.
If you have dry skin keep showers under ten minutes. Once a day is enough. Lukewarm temps only.
Will the summer be easy? Probably not. But it might be bearable if you respect the heat and hide from the pollen.
“It can help restore the skin’s protective barrier and hydration,” says Marchbein.
