The baby's head is always hot, and it feels like a fever when touched, but the temperature is not high when measured.

Patient's question:

No

Doctor's answer:

Low-grade fever refers to a body temperature between 37.3℃ and 38℃. Many diseases can cause low-grade fever. Fever is a symptom, and conditions such as rheumatism, tuberculosis, chronic inflammation, and low immunity can lead to persistent low-grade fever. Long-term psychological stress and emotional instability can also disrupt the body's temperature regulation center, resulting in persistent low-grade fever. The key is to identify the underlying cause, as indiscriminate medication for unknown low-grade fever should be avoided.
