In recent years, the number of dermatitis patients has kept rising, among which allergic dermatitis is prevalent. Its main symptom is unbearable itching that disrupts daily life and work and brings great distress to sufferers. To prevent recurrent attacks and stop the condition from developing into chronic allergic dermatitis, it is essential to identify its triggering factors.

Causes of Allergic Dermatitis

Weather and environmental factors

Long-term skin exposure to strong sunlight or polluted air damages the skin barrier and thins the epidermal layer, making the skin vulnerable to inflammatory lesions.

Physiological factors

Mental tension and excessive stress disrupt endocrine balance, weaken the skin’s natural defense and slow down its self-repair capacity.

Allergens

Contact with allergens is the primary trigger of allergic dermatitis. Common irritants include pollen, cosmetics, and certain foods.

Genetic factors

Allergic dermatitis is hereditarily linked. People with an inherited allergic diathesis have a significantly higher risk of developing the condition.

Dietary factors

Regular intake of spicy and highly stimulating foods generates internal heat, which facilitates the onset of allergic dermatitis.

Psychological factors

Prolonged severe stress disturbs systemic metabolism and endocrine function, inducing skin allergic inflammation.

Preventive Measures Against Allergic Dermatitis

Moderate outdoor activities

Gradually expose the skin to small doses of ultraviolet radiation and slowly increase exposure duration to boost skin tolerance to sunlight.

Limit photosensitive foods

Reduce intake of photosensitive vegetables such as rape, spinach and lettuce. Their special ingredients heighten skin sensitivity to UV rays.

Standardized skin care

During high-risk allergy seasons (spring and autumn), people prone to allergies should stop using cosmetics and stay away from all identified allergens.

Important Reminder

Allergic dermatitis deserves full attention. Severe flare-ups may even trigger anaphylactic shock that threatens life. Many minor daily details can trigger the disease, so consistent preventive care is indispensable and must not be overlooked.
