If you’re living with atopic dermatitis, commonly known as eczema, you know that a bad episode of itchiness and inflammation can subside, only to flare up again — often worse than before.
“With atopic dermatitis, an overall worsening state could mean someone is experiencing an increase in the baseline severity of their flares, seeing an uptick in the total number of flares per year, or both. It really depends on the individual,” says Jonathan Silverberg, MD, PhD, an associate professor of dermatology at The George Washington School of Medicine in Washington, DC, and a leading researcher on the condition.
While there are treatments to help ease symptoms — and you should talk to your doctor if you find your discomfort growing — there are also behaviors you can change that might make a difference. That involves identifying how you might be aggravating your atopic dermatitis.
Here, experts offer insights on eight ways you’re making your eczema worse and what to do instead.
1. Not Taking Enough Care During Winter
Unless you’re living in a tropical climate, it’s nearly impossible to avoid the changes in temperature and air quality that come with winter. For people with atopic dermatitis, who have a genetic defect in a skin protein that makes the epidermis unable to lock in moisture, the drying effect of those cold, low-humidity months can be especially harmful.
“For some patients, their skin remains extra dry for the entire three or four months of winter, and they’ll find they can’t even handle showering or their regular personal care products like they used to,” says Dr. Silverberg.
Expert tip: First, run a humidifier all winter, says Angela Lamb, MD, an associate professor of dermatology at the Icahn School of Medicine at Mount Sinai in New York City. “Then, make sure you’re using moisturizers at least twice a day, especially within a few minutes of getting out of the shower, so you can lock in that moisture,” she adds.
2. Getting Stressed Out
The body’s physiological reaction to stress is the same whether the worry is temporary or chronic. The response, referred to as fight or flight, starts with the release of a cascade of stress hormones — namely, cortisol and adrenaline — that suppress the immune system and increase inflammation.
For people with atopic dermatitis, this inflammation can impair skin barrier function, research has shown, and potentially lead to more frequent flares. When stress is chronic and the immune system is suppressed for a length of time, you can also become vulnerable to more severe rashes, because the skin can’t fight off pathogens as it normally would.
“It’s almost inevitable that if someone with atopic dermatitis is going to be in a stressful situation, they’re going to flare,” says Silverberg.
Expert tip: Stress can be hard to manage, but tried-and-true stress busters, such as mindful breathing and yoga, can make a difference.
For some people, preventive drug therapy can also help. “We recommend the use of something called proactive therapy,” Silverberg says. “If you know you’re about to enter a stressful situation or period of work, why wait for a flare to happen? You can get ahead of it by using medications like steroid creams and other treatments on areas prone to flaring.”
Silverberg notes that this is not something he would recommend for every person with atopic dermatitis, so follow the guidance of your healthcare provider.
3. Indulging Occasionally in Long, Hot Showers
While a leisurely, hot soak may feel relaxing, extended exposure to hot water can strip the skin of moisture and essential oils, leaving the outer skin disrupted and more likely to flare, says Dr. Lamb. “It’s a balance, because washing and getting the skin wet is actually good for people with eczema.” That’s because water washes off any bacteria or irritants on the skin that might cause or exacerbate a flare-up.
Expert tip: Shower or bathe in water as cool as you can stand, wash with a gentle cleanser, and then lightly pat yourself dry. Within three minutes of coming out, “Wrap in that moisture with a really good, thick moisturizer,” says Lamb.
4. Using Products With Fragrances, Chemicals, or Preservatives
“Personal care products are definitely a major trigger for patients with eczema,” says Silverberg. That’s because fragrances, preservatives, surfactants, and other ingredients in these and other items, such as laundry detergent, can trigger itching and irritation that can make flares worse. A study reported that about 10 percent of people with contact hypersensitivity to topical preparations containing fragrances and preservatives (among other things) also have atopic dermatitis. The study found that prolonged use of these products can increase the risk of contact hypersensitivity and, as a result, cause an exacerbation in people with atopic dermatitis.
Expert tip: “Remember, ‘clean’ products, which I recommend to patients, doesn’t automatically mean natural or organic, because sometimes those contain essential oils and other ingredients that may be naturally derived but can also be quite harsh to the skin,” says Silverberg.
Make sure you avoid common skin-care additives that are known to irritate eczema, and look for fragrance-free, dye-free products with as few ingredients as possible, he adds.
5. Wearing Wool or Synthetic Fabrics
Certain synthetic materials, including nylon and polyester, don’t “breathe” well, leading to overheating, sweating, and irritation, especially in warm weather and during physical exertion.
Wool may be breathable and naturally moisture wicking, but it’s often too scratchy or rough for people with atopic dermatitis and can trigger itching that leads to worsening flares.
Rough seams, labels, and fasteners can also rub, causing additional issues for sensitive skin.
Expert tip: Not all wool is created equal: Fine-woven merino and soft cashmere may not cause the same aggravation to skin. In fact, a study found that wearing a base layer of fine merino wool lessened the severity of outbreaks for people with atopic dermatitis, which the authors suggest could be due to less friction against the body.
Aside from that, “Eczema patients typically do best with loose-fitting, cotton-fiber clothes,” says Silverberg. Clothing made of silk or bamboo should also be fine, but cut out any labels that might scratch.
And, be sure to wash all of your new clothes before wearing them, to remove any residue.
6. Getting Hot and Sweaty From a Workout
Quick changes in body temperature that occur when running, biking, or even walking can further inflame a flare and itch. So can sweat.
Still, the benefits of exercise are inarguable. “I’ve had patients come to me and say that other healthcare providers told them not to exercise, to avoid heat and sweat, and I think that that is highly inadvisable. The overall benefits of exercise on our health and longevity are essential,” says Silverberg.
Expert tip: Make sure your workout clothes are eczema friendly. “Loose-fitting, breathable fibers are going to be much better tolerated on the skin than a tight spandex that can really have a lot of friction and buildup of heat and sweat,” says Silverberg.
After your workout, immediately take a cool shower or bath, says Silverberg. Then, lightly pat yourself dry, add moisturizer, and apply any topical medication your doctor has prescribed.
Finally, remember that even a lower-intensity workout can be good for you. “You don’t need to be dripping in sweat to get the benefits of exercise,” says Lamb.
7. Scratching Your Itch
It’s hard not to scratch when a main symptom of eczema is terrible itching. And, when you do things that can make a flare feel worse, such as getting overheated, resistance can feel futile. “Whenever you raise your body temperature and start sweating, you get a histamine release, which can create more intense itching,” says Lamb. “Then, if you do scratch, the itching just gets worse, and it can become a chronic itch-scratch cycle.”
Expert tip: “If you feel the need to scratch, try patting yourself instead,” says Lamb. She also encourages using cool compresses, which can calm the inflammation. “Take a damp washcloth, put it in the refrigerator or freezer for a little while, and then just apply it to your skin,” she says. “It’s very soothing and really takes down that itch.”
If those methods don’t work, and you feel stuck in an itch-scratch cycle, talk to your doctor about whether you’re a good candidate for an oral or injectable medication to help calm the flare.
8. Staying Outdoors in the Heat
For some people, the summer months bring a reprieve from eczema flare-ups, but for others, it’s just the opposite.
Although heat can cause an inflammatory response in the skin that may intensify an itching sensation — leading you to scratch and potentially worsen the rash — the more likely culprit is sweat, according to the National Eczema Association.
Perspiration lowers body temperature on hot days, but for people with atopic dermatitis, research has shown that sweating can exacerbate the condition in two ways: by removing moisture from the outer layers of skin through evaporation, making skin drier and more susceptible to a flare, and by leaving behind an acidic residue of natural chemicals, including urea, lactate, and minerals, which can irritate rashes even further.
Expert tip: If you’re headed outside on a hot day, wear loose-fitting clothes made from a breathable material such as cotton, says Silverberg. If you find your clothes are getting damp, because you’re sweaty, change into a new outfit as quickly as possible, so the wet fabric doesn’t cling to your skin, potentially aggravating your eczema.
As soon as you can, “Take a cool shower to help bring down your body temperature and rinse the irritating sweat off,” Silverberg says.
The Takeaway
Certain everyday habits can aggravate atopic dermatitis symptoms, but changing those behaviors can help make a difference.
Avoiding long, hot showers, adjusting your skincare routine in the winter, choosing fragrance-free products, and reducing stress are just a few habits that can help you manage atopic dermatitis.
Talk to your doctor if you still experience discomfort despite following an atopic dermatitis-friendly routine.
