Although 37.1℃ is a normal body temperature and is not considered a fever, if it is combined with other symptoms such as fever, chills, sneezing, nasal congestion, dizziness, headache, cough, coughing and other symptoms, you should monitor your body temperature, drink more water, keep warm and give symptomatic treatment for other symptoms.

In clinical practice, antipyretics should be used only if the body temperature is higher than 38.5℃.
