36.5–37.5 °C (97.7–99.5 °F)
Normal human body temperature varies slightly from person to person and by the time of day. Consequently, each type of measurement has a range of normal temperatures. The range for normal human body temperatures, taken orally, is 7002309950000000000♠36.8±0.5 °C (7002309927777777777♠98.2±0.9 °F). The normal human body temperature is often stated as 36.5–37.5 °C (97.7–99.5 °F). In adults a review of the literature has found a wider range of 33.2–38.2 °C (91.8–100.8 °F) for normal temperatures, depending on the gender and location measured. Most people think a normal body temperature is an oral temperature (by mouth) of 37°C (98.6°F) . This is an average of normal body temperatures. Your normal temperature may actually be 0.6°C (1°F) or more above or below this. Also, your normal temperature changes by as much as 0.6°C (1°F) during the day, depending on how active you are and the time of day. Body temperature is very sensitive to hormone levels. So a woman's temperature may be higher or lower when she is ovulating or having her menstrual period Most people think of 'normal' body temperature as 37C (98.6F), measured using a thermometer in the mouth. 'A Critical Appraisal of 98.6F, the Upper Limit of the Normal Body Temperature, and Other Legacies of Carl Reinhold August Wunderlich', JAMA. 1992;268(12):1578-1580. 'Normal Body Temperature: Rethinking the normal human body temperature', Harvard Health Publications. NHS Direct. Fever symptoms. A fever is a high temperature when the body's temperature rises above 37.5C (99.5F). The normal body temperature is between 36C-37C (96.8F-98.6F). The high temperature or fever often lasts around two to three days. Check for high temperature or fever using an appropriate thermometer and following the instruction Most people think of a normal body temperature as an oral temperature of 98.6°F (37°C) . This is an average of normal body temperatures. Your temperature may actually be 1°F (0.6°C) or more above or below 98.6°F (37°C) . The body is very good at keeping its temperature within a narrow, safe range in spite of large variations in temperatures outside the body. When you are too hot, the blood vessels in your skin expand (dilate) to carry the excess heat to your skin's surface. Normal human body temperature, also known as normothermia or euthermia, depends upon the place in the body at which the measurement is made, the time of day, as well as the activity level of the person. Nevertheless, commonly mentioned typical values are: The normal human body temperature is often stated as 36.5–37.5 °C (97.7–99.5 °F).
