35.7 degrees is not considered to be a case of low fever. Low fever means that the body temperature is above the normal range, but within a certain range, for example, when the body temperature is measured in the armpit, the normal temperature is between 36-37 degrees, as long as the body temperature exceeds 37 degrees, it is considered to be a case of fever. However, when the body temperature is limited to 37-38 degrees, it is called a case of low fever. Therefore, 35.7 degrees is not considered a low fever, but a little low temperature is not very serious. First of all, it is necessary to exclude the low temperature caused by the measurement error, because it is not easy to clamp the thermometer when the temperature is measured in the armpit, in addition, if there is sweat in the armpit, it will also appear low temperature measurement phenomenon. If you exclude the error of measurement, the cold environment will also lead to low body temperature, wear more or drink some hot water can effectively raise the body temperature. In addition, if you take an overdose of antipyretic medication can also easily lead to hypothermia, drink more hot water, pay attention to keep warm, and promote the metabolism of drugs, the body temperature can rise.
