What causes dyshidrotic eczema in children?

The causes of dyshidrotic eczema in children are diverse, primarily including the following aspects: 1. Allergic reactions: Children may develop skin allergies due to contact with certain substances such as foods, medications, cosmetics, or detergents, leading to dyshidrotic eczema. 2. Environmental factors: Hot and humid environments, prolonged water exposure, or hot weather may cause impaired sweat excretion in children's skin, thus triggering dyshidrotic eczema. 3. Genetic factors: Some children may be more susceptible to dyshidrotic eczema due to genetic factors. If parents or close relatives have a history of dyshidrotic eczema, the child's risk of developing the condition may increase. 4. Psychological factors: Children experiencing tension, anxiety, or excessive academic pressure may also develop dyshidrotic eczema. 5. Other factors: Malnutrition, dry skin, other illnesses (such as hand-foot-and-mouth disease, chickenpox), or skin irritation from external friction or stimuli may also contribute to the occurrence of dyshidrotic eczema in children. During treatment, appropriate methods should be selected based on the specific cause, and proper daily care and preventive measures should be emphasized.
