The causes of allergies in children are varied, mainly including the following aspects:
1. **Genetic factors**: If there is a family history of allergies, the child's risk of developing allergies increases accordingly. Genetic factors play an important role in the development of allergies.
2. **Environmental factors**: Allergens in the air, such as pollen, dust mites, mold, and pet dander, can all trigger allergic reactions in children. In addition, air pollution, cold air, and large temperature differences between indoor and outdoor environments may also trigger allergies.
3. **Dietary factors**: Certain foods, such as milk, eggs, peanuts, tree nuts, soybeans, fish, and shellfish, are common allergenic foods. Additives and food colorings may also cause allergic reactions.
4. **Contact allergies**: Children may develop skin allergies after coming into contact with certain chemical substances, such as detergents, soaps, cosmetics, and some plants.
5. **Medication allergies**: Medications such as antibiotics and vaccines may also cause allergic reactions in children, manifesting as symptoms like skin itching and hives.
