For the average person, a body temperature of 37°C is not considered feverish. Diagnostically speaking, this body temperature is within the normal range. However, there are some special people who may have a low basal body temperature, so when the body temperature reaches 37℃, it should be considered feverish and there will be physical discomfort, this situation needs to go to the hospital to identify the cause and timely symptomatic treatment. Normal body temperature values: oral sublingual temperature of about 37 ℃ (range 36.3-37.2 ℃ are normal); rectal temperature of 37.5 ℃, higher than the oral temperature of 0.3-0.5 ℃; axillary temperature range 36.0 ℃ -37.0 ℃ is normal. Body temperature varies at each specific time of day, generally between 2:00 to 5:00 in the morning body temperature may be at a lower level; and by 1:00 to 5:00 in the afternoon, a person’s body temperature is relatively high. During some special physiological periods, a woman’s body temperature may change, for example, it is lower during ovulation and may be a little higher than usual during the menstrual cycle. Body temperature is not fixed for different people and different genders. For example, the body temperature of newborns is more influenced by the external temperature, plus the neurological development is not yet complete, so the body temperature is higher compared to adults; while some older people have a low metabolic rate and may have a lower body temperature. When emotionally excited, the body’s sympathetic nerves are excited, the heartbeat is accelerated, and the body’s metabolism increases, which may lead to a higher than normal body temperature. Generally speaking, a body temperature of 37℃ is not considered a fever; however, for people with a low basal body temperature, a body temperature of 37℃ accompanied by physical discomfort, it is better to go to the hospital for examination, except for fever caused by infection.
