[Health Column] Bathing and Showering for Atopic Dermatitis: How Should You Adjust Water Temperature and Duration?

Hello, this is Dr. Park Chi-young, Chief Director of Saenggi Korean Medicine Clinic Gangnam Station Branch.

If you have atopic dermatitis, you may have concerns every time you take a shower. Many people are confused because their skin feels tighter or itchier after washing, asking, "Should I avoid washing too often?" or, conversely, "Isn't it good to thoroughly wash away sweat and impurities?"

For atopic skin, water temperature, shower duration, the use of cleansers, and post-wash moisturizing methods are just as important as the frequency of washing. This is because even if you wash the same number of times, the skin's reaction can vary depending on how you wash.

Today, I will explain step-by-step atopic bathing methods and showering habits to reduce unnecessary irritation to the skin.

I. How is the atopic bathing method different from a regular bath?

Atopic dermatitis is characterized by a weakened skin barrier that causes moisture to easily escape and a sensitive reaction to external stimuli. Therefore, rather than focusing on washing the skin until it is squeaky clean, it is better to aim for bathing to gently remove sweat and pollutants while reducing irritation to the skin barrier.

In particular, the habit of soaking in hot water for a long time or taking long showers can make skin dryness and itching more uncomfortable. The basics are to use lukewarm water that is not too hot and not wash for longer than necessary.

If your skin feels severely tight, turns red, or itching increases after washing, you need to check if your current water temperature, bathing time, and cleansing habits are suitable for your skin condition. Your skin's reaction after showering is the most honest indicator.

II. How should I adjust the water temperature and duration for an atopic shower?

The important thing when showering for atopic dermatitis is to avoid prolonged exposure to heat and irritation. While washing with hot water may make it feel like itching is relieved momentarily, the skin can become dry and sensitive afterward.

Therefore, it is better to use lukewarm water that feels comfortable rather than water hot enough to make your skin burn. Similarly, instead of taking a shower that is longer than necessary, it is helpful to finish briefly just enough to wash away sweat and dirt.

However, the appropriate frequency and duration of bathing may vary depending on the season, amount of sweat, degree of skin dryness, and the presence of discharge. The standards for days with heavy sweating in the summer cannot be the same as those for dry winter days.

Above all, it is important to observe how your skin reacts after showering and adjust the dosage according to your condition. Think of it as a process of finding a comfortable range for your skin, rather than strictly adhering to a set number.

III. How should atopic soaps or cleansers be used in atopic bathing methods?

Having atopic skin does not mean you must absolutely avoid using soap. While areas heavily contaminated with sweat, dust, or external pollutants require proper cleansing, it is best to avoid scrubbing vigorously or using excessive amounts of cleanser.

When choosing soaps or cleansers for atopic dermatitis, you should check whether your skin feels excessively tight or stinging after use, rather than judging solely by the product name. This is because the label "for atopic dermatitis" does not guarantee that it is suitable for everyone.

Rather than scrubbing repeatedly with a rough shower towel, please wash gently with your hands and rinse thoroughly to ensure no cleanser remains on your skin. It is not uncommon for leftover cleanser ingredients to irritate the skin.

After showering, it is recommended to avoid scrubbing your skin vigorously; instead, gently pat it dry with a towel and then apply moisturizer. Similarly, choosing clothing made of materials that are less irritating and breathable, rather than those that cause repeated friction against the skin, can also be helpful.

IV. What is the reason for recurring itching even though I bathe regularly?

The condition of atopic dermatitis is not determined solely by bathing habits. Even with the same skin symptoms, there are cases where heat sensation and redness are prominent, whereas others exhibit severe dryness and scaling; furthermore, management methods can vary depending on whether the skin is oozing repeatedly or has thickened and roughened skin.

In Korean medical treatment, not only skin conditions but also changes in digestive status, sleep, stress, and lifestyle rhythms are examined. Depending on the individual's condition, the approach may involve considering herbal medicine while simultaneously adjusting lifestyle habits and applying topical treatments to manage skin itching or dryness.

In particular, it is advisable to use moisturizer appropriately after bathing and to examine whether there are any lifestyle factors that worsen symptoms, such as excessive drinking or lack of sleep. During periods of severe skin symptoms, it is important to adjust care methods according to your current skin condition rather than applying a one-size-fits-all approach.

V. When should I consider seeking medical attention if symptoms of atopic dermatitis persist even after changing my bathing routine?

If you have been consistently managing your lifestyle but itching keeps you awake at night, if scratches and oozing occur repeatedly, or if skin symptoms interfere with your daily life, it is advisable to have your current condition checked by a medical professional. Even if your skin suddenly swells severely or you experience pain or a sensation of heat, medical attention may be necessary rather than relying solely on self-care.

Atopic dermatitis management needs to be approached from the perspective of managing the acute phase, maintaining stability, and managing recurrence factors, rather than stopping at merely alleviating severe symptoms. Even after symptoms subside, identifying factors that affect you—such as seasonal changes, overwork, stress, and lack of sleep—allows you to respond to changes a little earlier.

The duration of treatment and management varies significantly from person to person, depending on the duration of atopic dermatitis, current skin condition, previous treatment history, and living environment. If you are currently using any medications or topical treatments, you should consult with your medical team to adjust them rather than arbitrarily stopping or reducing them.

When choosing a medical institution, it is advisable to check whether they thoroughly assess your skin condition and lifestyle factors and explain a step-by-step management plan, rather than emphasizing just one treatment.

🍵 Frequently Asked Questions

Q1. Is it okay to shower every day if I have atopic dermatitis?

You do not need to uniformly avoid washing every day. Since there are individual differences such as how much you sweat or how dry your skin is, you should consider not only the frequency but also the water temperature, washing method, and moisturizing after showering.

Q2. Washing with hot water relieves the itching. Is that okay?

While hot water may feel momentarily cool or refreshing, it can increase skin dryness or irritation. Although individual differences exist, lukewarm water at a comfortable temperature is generally recommended rather than water hot enough to cause a sensation of heat on the skin.

Q3. Do I have to use a product specifically designed for atopic dermatitis?

It is difficult to determine if a product is suitable for everyone based solely on the label "for atopic dermatitis." You should check for any tightness or stinging sensations after use, as individual differences exist depending on skin condition and the product.

Q4. When is the best time to apply moisturizer after showering?

Adopting the habit of gently drying the skin after washing and applying moisturizer before it dries out can be helpful. However, since general moisturizing care may not be suitable depending on the skin condition, such as in areas with oozing or severe wounds, it is advisable to consult a medical professional.

Q5. Can I receive Korean traditional medicine treatment in conjunction with conventional atopic dermatitis treatment?

The assessment may vary depending on current medications, topical treatments, and skin condition. It is important not to arbitrarily stop or reduce existing treatments, but to adjust the treatment plan in consultation with your healthcare provider.

🌿 Wrapping up

The important thing in bathing for atopic dermatitis is not simply distinguishing between washing frequently or not washing at all. You must manage a water temperature that does not irritate the skin, showering habits, proper cleansing, and moisturizing after bathing together.

Furthermore, even among those with the same condition of atopic dermatitis, current skin conditions—such as dryness, heat, and oozing—vary, so lifestyle management methods need to be adjusted to suit the individual. It is recommended to observe how your skin changes after showering and start by changing the habits that cause you discomfort, one by one.

If itching and skin damage persist despite lifestyle management, do not attribute the issue solely to your bathing method; instead, examine your current skin condition and any aggravating factors. If necessary, it is advisable to consult with a medical professional to determine the appropriate treatment and management plan for your specific condition.
