Why does the palm become red and itchy when rolling dumpling wrappers?

Generally, redness and itching in the palms during rolling dumpling wrappers may be caused by flour irritation, excessive friction, contact dermatitis, dyshidrotic eczema (sweat blisters), or tinea manuum (fungal infection of the hands). If discomfort occurs, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. Detailed analysis is as follows:

1. Flour Irritation

Proteins or dust particles in flour may irritate the delicate skin of the palms, triggering a localized reaction. Wearing thin cotton gloves when handling flour and rinsing the palms with lukewarm water afterward can help. Apply a gentle hand cream to moisturize the skin.

2. Excessive Friction

Repeated rubbing between the palms, rolling pin, and dough during wrapping may damage the skin's stratum corneum, leading to redness and itching. Reduce the duration of each rolling session, alternate between both hands, and use a smooth-surfaced rolling pin.

3. Contact Dermatitis

Allergic reactions to additives in dumpling flour or materials of the rolling pin activate the immune system, causing inflammation. Treatments such as mometasone furoate cream, loratadine tablets, or cetirizine hydrochloride drops may be used under medical guidance. Avoid re-exposure to the allergen.

4. Dyshidrotic Eczema (Sweat Blisters)

Excessive sweating during rolling can cause sweat to become trapped beneath the skin, resulting in a blistering skin condition accompanied by redness and itching. Under medical supervision, treatments like calamine lotion, hydrocortisone butyrate cream, or vitamin E emulsion may be applied. Keep the palms dry.

5. Tinea Manuum (Hand Fungus)

Fungal infection of the palm skin may worsen in the warm, moist environment created while rolling wrappers, causing redness and itching. Antifungal medications such as terbinafine hydrochloride cream, clotrimazole solution, or itraconazole capsules may be used as directed by a physician. Avoid sharing rolling tools with others.

In daily life, take preventive measures before handling ingredients: protect your hands, maintain hand hygiene and dryness, wipe away sweat promptly, choose natural flour without additives, and avoid scratching when symptoms appear to prevent secondary infections.
