[Health Column] Atopic Itching: Why It Worsens at Night and How to Manage Nocturnal Pruritus

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

It is not uncommon for patients receiving treatment for atopic dermatitis to say, "It is bearable during the day, but it gets unbearably itchy at night." They may wake up scratching their skin in their sleep or discover the next morning that the wounds have expanded.

In particular, if itching recurs at night, it can lower the quality of sleep, leading to a vicious cycle where fatigue and stress further affect the skin condition. Today, I will explain step-by-step the reasons why atopic itching recurs and the points to consider when managing nocturnal pruritus.

I. Why does atopic itching occur?

The itching associated with atopic dermatitis cannot be viewed simply as a symptom caused by dry skin. As the skin barrier weakens, it becomes sensitive to external stimuli, and if the inflammatory response persists, it becomes easy to feel itching even from minor irritations.

The problem is that scratching due to itching damages the skin barrier again. Damaged skin becomes more sensitive, and as inflammation and itching recur, a so-called 'itch-scratching' cycle can continue. Therefore, it is important not only to get through the moment of itching but also to examine the conditions that cause the skin to repeatedly become sensitive.

II. Why does atopic itching get worse at night?

Several factors can contribute to itching worsening at night. When you go to bed, surrounding activities and stimuli decrease compared to the day, making it easier to focus on the itchy skin; additionally, the sleep environment, such as bedding and room temperature, can also have an impact.

In particular, if the room is hot or thick blankets cause your body temperature to rise and lead to sweating, the skin becomes irritated, making nocturnal itching feel more uncomfortable. Repeatedly scratching while asleep when the skin is dry is also a factor that increases skin damage.

If you are unable to sleep properly due to nocturnal itching, fatigue and stress may increase the next day. Since these changes can, in turn, affect your skin condition, it is advisable to monitor your sleep patterns as well as the intensity of the itching.

III. How does Korean traditional medicine approach recurring nighttime itching?

In Korean medical treatment, even for the same case of atopic itching, the direction of treatment is determined by examining both the skin condition and the patient's overall health. This is because it is difficult to approach cases involving redness, intense heat, and itching in the same way as cases involving dry skin with excessive keratinization that causes itching.

We assess not only skin symptoms such as oozing, redness, and dryness, but also factors like digestive status, sleep quality, stress, and fatigue. We apply herbal medicine treatment considering the individual's constitution and current condition, and approach the treatment by combining topical care with lifestyle management depending on the skin condition.

IV. What are some common incorrect management practices for nocturnal pruritus?

The most important thing to watch out for is scratching your skin hard or washing with hot water because you find it difficult to resist the itch. While it may feel cool or refreshing for a moment, it can cause additional irritation to the skin.

In addition, you should avoid arbitrarily and suddenly stopping existing medications or steroids just because your symptoms have improved slightly. Since reducing or changing existing treatments requires consideration of skin condition and duration of use, it is important to consult with your medical team before making adjustments.

The recovery process is also not the same for everyone. Even if redness subsides, dryness or itching may persist, and conversely, symptoms may temporarily fluctuate at certain times; therefore, rather than judging the progress of treatment based on a single symptom, you should examine the overall changes.

V. In what cases should I consider seeking medical attention?

If you frequently wake up from sleep due to itching or develop wounds from constantly scratching while asleep, you need to review your current care methods. It is also advisable to seek an evaluation from a medical professional if oozing or skin damage recurs, or if discomfort in daily life and sleep persists despite your existing care.

Managing atopic dermatitis does not end with merely alleviating discomfort during the acute phase; it is also crucial to maintain a stable condition and monitor factors for recurrence. Identifying conditions that repeatedly affect you, such as seasonal changes, overwork, stress, and lack of sleep, helps you respond more quickly when symptoms flare up again.

🍵 Frequently Asked Questions

Q1. Does atopic itching decrease immediately with treatment?

A1. Since the causes of itching and skin conditions vary from person to person, there are individual differences in the rate of change. It is important to monitor the progression by examining factors such as skin inflammation, the degree of dryness, sleep, and living environment.

Q2. How should I deal with severe itching at night without scratching?

A2. The basics are to keep the bedroom from getting too hot and to maintain proper moisture to prevent the skin from drying out. Keeping your fingernails short to reduce skin damage from scratching while asleep can also be helpful, but appropriate care methods vary from person to person depending on skin condition.

Q3. Can I combine existing steroids with traditional Korean medicine treatment?

A3. The treatment plan may vary depending on prior treatment and skin condition. In particular, do not arbitrarily stop or reduce your medication; you must adjust it through thorough consultation with the prescribing medical team.

🌿 Wrapping up

Atopic itching, especially recurring itching at night, can be influenced by various factors including not only the skin itself but also the sleep environment and lifestyle habits. Therefore, rather than simply aiming to 'not scratch,' it is necessary to examine what is making the skin sensitive.

Start by examining your daily lifestyle conditions, such as showering habits, moisturization, bedroom temperature, and sleep patterns. Even after your symptoms improve, it is important to maintain a stable state by identifying the factors that cause recurrence and affecting you.

In particular, if you frequently wake up at night due to itching or experience recurring skin damage and oozing, it is advisable to have your current condition accurately evaluated rather than trying to diagnose yourself. Since treatment methods and adjustments to existing medications can vary depending on an individual's skin condition and treatment history, please consult with a medical professional to make a careful decision.
