Why Stress Triggers Flare-Ups of Dermatitis, Eczema, and Psoriasis

Our skin is not only an external barrier but also a reflection of how the nervous and immune systems function. When the body is under stress, its response to both external and internal factors changes. That is why chronic skin conditions such as dermatitis, eczema, and psoriasis often flare up during periods of stress.

How stress affects the skin

The connection between the skin and the nervous system has long been studied. A review published in the journal Brain, Behavior, and Immunity notes that psychological stress is a significant factor in the development of many skin diseases. Under stress:

• inflammation increases

• immune system function changes

• skin sensitivity rises and wound healing worsens

• the skin barrier function becomes impaired

Scientific studies also show that stress intensifies itching in skin conditions through the activation of mast cells — key immune cells in connective tissue that protect the body. This creates a kind of vicious cycle: as itching increases, stress levels rise, which in turn further impacts the skin. Skin symptoms themselves also become an additional source of stress for patients.

Elena Lysogorskaya, neurologist at Kandinsky Clinic, PhD:

“The skin and the nervous system are closely connected. Stress affects immune processes and inflammation, so patient assessment should be comprehensive — especially in chronic skin conditions.”

Mechanisms linking stress and skin diseases

There are at least three ways in which stress can affect the skin, each requiring a different approach.

• First, stress can trigger conditions associated with repetitive skin damage — for example, compulsive scratching, picking, or other behaviors.

• Second, stress can worsen existing chronic skin diseases. This mechanism is most commonly seen in psoriasis, eczema, and dermatitis: under emotional strain, symptoms become more pronounced and the course of the disease less stable.

• Third, stress can act as a trigger for new conditions, when the first symptoms appear after significant emotional stress or major life events.

Skin symptoms associated with stress

When skin conditions first appear or worsen due to stress, patients most often report:

• intense itching

• redness and inflammation

• dryness and flaking

• a burning sensation

• overall deterioration of skin condition

It is important to understand that symptoms may intensify even without changes in external factors — purely due to internal tension.

Dermatitis, eczema, and psoriasis: complex conditions with multifactorial activation mechanisms

Dermatitis, eczema, and psoriasis are chronic skin diseases in which inflammation is sustained over time and depends on multiple factors—immune, behavioral, and environmental.

Dermatitis

In dermatitis, stress can increase skin sensitivity and disrupt the protective barrier. This leads to dryness and stronger reactions to everyday irritants. Itching often intensifies, which promotes scratching and perpetuates inflammation.

Eczema

Eczema is characterized by an unstable course, and stress often becomes the trigger for another flare. Under these conditions, the skin recovers more slowly and inflammation may persist longer than usual.

Psoriasis

Psoriasis is a systemic skin disease involving abnormal skin cell turnover. Stress can amplify immune responses, leading to new lesions or enlargement of existing ones. In some patients, the first manifestations appear after significant emotional strain.

In addition to dermatitis, eczema, and psoriasis, stress can affect other chronic skin conditions such as acne, seborrheic dermatitis, and urticaria. In these cases, emotional stress can also increase inflammation, heighten skin sensitivity, and trigger new breakouts.

Why it is important to consider stress in treatment

If the impact of stress is ignored, treatment may provide only temporary relief — until the next flare. This is because stress sustains inflammation and interferes with skin recovery.

That is why in such cases it is often necessary to address not only the skin but also the nervous system.

Alesya Yurakova, dermatologist at Kandinsky Clinic:

“Even with properly selected therapy, results may be incomplete if the impact of stress is not taken into account. In such cases, it is important to take a comprehensive approach — addressing both the skin and the factors that sustain inflammation.”

When to see a doctor

If you notice that dermatitis, eczema, psoriasis, or other skin conditions worsen during periods of stress, it is important not to delay consultation.

This is especially important if:

• symptoms recur regularly

• symptoms become more severe

• standard treatment is ineffective

• quality of life is affected

For initial evaluation, you can schedule an appointment with a general practitioner at Kandinsky Clinic in Dubai. The doctor will assess your overall condition and recommend further steps.

Anti-stress skin check-up at Kandinsky Clinic

For a more comprehensive assessment, Kandinsky Clinic offers an anti-stress skin check-up, which includes:

• consultation with a dermatologist

• consultation with a neurologist

• dermatological screening (skin check) with evaluation of moles, pigmentation, and other lesions

Examinations are conducted by experienced Russian-speaking specialists with extensive clinical experience, helping to identify why the body is under strain. The clinic also has its own laboratory, allowing patients to complete necessary tests and receive results without long waiting times.

Additional check-ups

The clinic also offers programs designed to assess the impact of stress on other body systems:

• cardiovascular system

• gastrointestinal tract

This approach allows for a detailed analysis of health issues and timely correction of factors affecting overall well-being.

You can book an appointment via WhatsApp or by calling Kandinsky Clinic at +971 456 312 00.
