Fever in the middle of the night is a common symptom. A condition like fever in the middle of the night may be caused by viral cold. In viral cold, besides symptoms such as sneezing, runny nose, nasal congestion and cough, patients may also have general symptoms such as fever, headache and aching limbs. Especially in the early stage of viral cold, this symptom is more obvious, and it is easy to have fever repeatedly. First of all, it can be treated with fever-reducing medication. If the body temperature exceeds 38.5°C, you can take drugs such as ibuprofen orally to play a role in reducing fever, and in addition, you can also apply the method of warm water bath to physically cool down the temperature. In addition, if the symptoms are accompanied by a cold, you need to take oral anti-cold medication, such as 999 cold spirit, Banlangen granules and other drugs. In addition, during the cold period, we should pay attention to rest, avoid exertion, light diet and balanced nutrition. If the symptoms are still not relieved after 3-5 days of medication, we need to go to the hospital for further examination to clarify the diagnosis.
