Preventing dry skin involves a combination of lifestyle changes and skincare routines. Ensuring that the child is adequately hydrated by drinking plenty of water can help maintain skin hydration. Using a humidifier in the child's room can counteract the drying effects of indoor heating during winter months. Limiting bath time to about 10 minutes and using lukewarm water instead of hot can also help. Additionally, dressing children in soft, breathable fabrics like cotton can reduce skin irritation.
