Question
What causes a child’s pulse and heartbeat to increase when they have a fever?
Answer
Under normal circumstances, a child’s pulse and heartbeat will increase by 10 beats to cope with the rise in body temperature. Therefore, it is normal for a baby’s pulse and heartbeat to increase after they have a fever. If the pulse and heartbeat return to normal after the fever subsides, there is no need to worry; just observe. However, if the pulse and heartbeat remain unusually fast even after the fever has subsided, it may be necessary to rule out other diseases, and it is recommended to go to the hospital for examination and treatment. In daily life, it is important to ensure that the child drinks plenty of water, stays warm, avoids catching a cold, and avoids eating spicy or hot foods.
