Baby's body temperature of 37.9 is not normal, but rather a low fever. Therefore, physical cooling measures should be taken to address the baby's fever symptoms, and the cause of the fever should be promptly identified so that targeted treatment and solutions can be provided. In particular, some viral infections may lead to a continuous rise in body temperature, so parents should observe carefully. Regarding how to deal with fever, generally, for babies with a fever of 38 degrees Celsius or below, it is not recommended to use fever-reducing medication immediately. Instead, physical cooling methods can be adopted, such as using lukewarm water to repeatedly wipe sweaty areas for fever reduction, or applying a fever patch. Most babies develop fever due to viral or bacterial infections, so identifying the cause promptly is crucial for quick resolution. It is also important to remind parents not to blindly believe in traditional remedies for fever reduction, as many older generations may have their own various fever reduction methods. However, from a scientific perspective, these remedies lack scientific basis and may cause harm if blindly applied to children. When a child has a fever, the best approach is to promptly perform physical cooling measures, followed by a formal further examination at the hospital, which can quickly diagnose the disease and provide targeted treatment.
