When taking body temperature, the temperature tends to be relatively low in the morning and high in the afternoon compared to the morning, perhaps 37.2°C in the afternoon. In fact, this is the normal pattern of temperature change. 24 hours of body temperature is not a constant level of body temperature, and the body temperature will increase during the daytime activities, to sleep at night the body temperature will drop. By the afternoon when there is a lot of activity, the afternoon body temperature will be slightly higher than the morning body temperature, drinking or eating, or appropriate exercise, will also make the body temperature increase. Therefore, a body temperature of 36℃ in the morning and 37.2℃ in the afternoon is normal and not a fever. Secondly, the body temperature is also related to each person’s basal body temperature. Some people have a relatively high basal body temperature level and may also show a higher body temperature in the afternoon. Content source: Dr. You Lai
