Why does a child with a fever experience headaches?

Fever refers to an elevated body temperature. Generally, possible causes of fever and headache in children may include lack of sleep, dehydration, affected thermoregulatory center, upper respiratory tract infections, meningitis, and so on. Symptomatic treatments such as general care and medication may be needed. If discomfort occurs, it is recommended to seek medical attention promptly and undergo corresponding treatment under a doctor's guidance. Detailed analysis is as follows:

1. Lack of sleep

If children experience sleep deprivation due to staying up late or academic stress, their brains may not rest adequately, making headaches more likely during fever. Symptoms may include fatigue and difficulty concentrating. It is recommended to improve sleep habits and ensure sufficient rest to help alleviate symptoms.

2. Dehydration

During fever, the body cools itself through sweating and other mechanisms. If fluids are not replenished timely, dehydration may occur. Dehydration can lead to concentrated blood, decreased blood pressure, and consequently reduced blood supply to the brain, causing headaches. Symptoms may include thirst, reduced urine output, and decreased skin elasticity. Encouraging children to drink more water and maintain adequate fluid intake is advised.

3. Impaired thermoregulatory center

During fever, the hypothalamus attempts to raise body temperature to a higher set point. This process may cause vasodilation and inflammatory responses, resulting in headaches. Symptoms may include chills, sweating, and loss of appetite. It is recommended that children with fever stay in a well-ventilated room, wear appropriate clothing, and avoid being overdressed.

4. Upper respiratory tract infection

Infections caused by viruses or bacteria can lead to upper respiratory tract infections. During such infections, inflammatory responses may stimulate nerve endings in the head, causing headaches. Symptoms may include fever, runny nose, and sore throat. It is recommended to follow medical advice in using medications such as ibuprofen capsules, cefaclor granules, oseltamivir phosphate capsules, and others to relieve symptoms.

5. Meningitis

Meningitis is a serious condition caused by pathogens infecting the meninges and brain tissue, which can lead to symptoms such as fever, severe headache, and vomiting. Meningitis may be accompanied by nausea, vomiting, and neck stiffness. It is recommended to follow medical advice in using medications such as penicillin V potassium tablets, amoxicillin granules, dexamethasone acetate tablets, and others to alleviate symptoms.

When children have a fever, providing bland yet nutrition-rich food such as millet porridge and steamed egg may help boost immunity and promote faster recovery.
