When a child has pneumonia, it is crucial to pay close attention to keeping them warm during the illness to avoid getting chilled. During this period, it is also necessary to prevent the child from overexerting themselves while playing. The child should have a light diet, low in salt and fat. Keep the indoor environment well - ventilated, avoid dry air, and maintain appropriate indoor temperature and humidity. During this time, it is also important to closely monitor the child's body temperature. If the body temperature exceeds 101.3°F (38.5°C), this indicates a high - fever state, and ibuprofen can be taken to reduce the fever. If the body temperature does not exceed 101.3°F (38.5°C), physical cooling methods can be used to bring down the fever. A warm, damp towel can be used to wipe the child's armpits and areas where large blood vessels are located, which can help with physical cooling. At the same time, the child should drink plenty of warm water. This can effectively prevent dehydration caused by fever and speed up the excretion of toxins in the body, thus preventing the pneumonia symptoms from worsening.
