When experiencing symptoms of a cold such as headache and fever, one should first measure their body temperature and adopt corresponding treatment measures based on the severity of the fever. Fever can cause headaches, fatigue, body aches, and may even lead to complications like nausea and vomiting. If the body temperature does not exceed 38℃ (100.4°F), one can take vitamin supplements, drink ginger tea, and use physical methods to reduce fever. If the body temperature is above 38℃ (100.4°F), one may consider taking antipyretic and pain-relieving medications like ibuprofen or aspirin to alleviate symptoms. Generally, once the body temperature returns to normal, headache symptoms will gradually improve or disappear. (The use of medications should be based on specific conditions and under the guidance of a doctor.)
