Eczema is prevalent in young children and often causes intense itching and skin damage with significant oozing, which can worsen especially in the fall and winter. Parents and friends often ask how eczema in children should be prevented. Although eczema is a chronic inflammatory disease of the skin with predominantly genetic factors, environmental triggers also play a key role in the onset and development of eczema. Therefore, avoiding known environmental irritants and keeping the skin clean and moist are important aspects of preventing recurrent eczema flare-ups. Not only does eczema cause physical discomfort in children, but frequent flare-ups can also have a significant impact on the child’s psychological development. Parents need to educate and help their children develop good skin care habits, such as warm baths and keeping the skin clean and moist, to avoid and reduce the recurrence of eczema. 1, dry skin is an important reason for the frequency of eczema (which does not contradict the exudation from the lesion area), eczema is not really wet skin, wet mainly refers to the skin exudation from the affected area. Hot baths tend to dry out the skin, especially in winter, and frequent hot baths should be avoided. Overly hot water and longer bathing times can lead to loss of skin moisture, loss of sebum components, and greater sensitivity to environmental allergens. Bathing should try to use warm water bath, the water temperature to not feel cold, and bath time should not be too long. 2, should choose a less irritating bathing solution, should not use aromatic soap. The area with skin lesions should avoid getting wet to prevent infection. At the end of the bath, try to pat the skin dry with a towel, do not use the towel to wipe the skin excessively. A skin moisturizer (such as petroleum jelly) can be used after the bath and applied evenly to the skin. Even when using hormonal creams, you can also use skin moisturizers at the same time. Just choose a regular mild moisturizer, you should avoid using moisturizers containing alcohol, because alcohol tends to aggravate dry skin. 3, clothing should be loose, soft, try not to give children wear easy to irritate the skin clothes, such as wool or rough woven materials, try to wear soft cotton fabrics. Bedding should also be made of cotton, avoiding wool and silk products. 4. In the rash area, you can use a towel for wet compresses to prevent itching and prevent skin damage. The child’s nails should always be clipped to reduce the skin lesions caused by scratching. Avoiding sweating and overheating can also reduce the recurrence of eczema. Any known allergens such as certain foods, dust, animal fur, should also be kept away as much as possible, especially in the home living environment, which should be kept clean and hygienic. 5, night itching often interferes with the child’s sleep, try to let the child wear comfortable clothes, if scratching is serious you can let the child wear gloves at night while sleeping. 6, food allergies are also an important cause of eczema attacks, should stay away from known allergic foods, diet should be light. Encourage your child to drink more boiled water, which helps to keep the skin moist. In addition, there are studies that breastfeeding and probiotic supplementation can reduce the occurrence of eczema, while the timing and dosage of probiotic supplementation has yet to be confirmed by further research. 7. Children with eczema are susceptible to skin infections, especially staphylococcal and herpes virus infections. Therefore, parents should promptly take their children to the doctor when they notice any early signs of skin infection, such as fever, redness, heat or pus in the rash area, or the appearance of skin herpes. Sudden changes or worsening of eczema symptoms should also prompt medical attention. Although recurrent eczema can be a distressing experience for both parents and children, it can be well controlled by taking active preventive measures and seeking timely medical help.
