When visiting humid or extremely hot regions, focus on internal and external cooling. Offer cooling, hydrating foods like cucumber, curd, ragi, and plenty of fresh fruit juices like watermelon or orange. Increase bath frequency to at least twice a day. To manage indoor temperatures, place buckets of water or hang wet clothes in the room to increase moisture and lower the ambient heat. If your child's skin is irritated or pink from the heat, barrier creams like Aquaphor can provide relief, and always prioritize staying indoors during peak sun hours.
