A range for normal temperatures has been found. Central temperatures, such as rectal temperatures, are more accurate than peripheral temperatures.<unk>  is generally agreed to be present if the elevated temperature is caused by a raised set point and: * Temperature in the anus (rectum/rectal) is at or over An ear (tympanic) or forehead (temporal) temperature may also be used. * Temperature in the mouth (oral) is at or over in the morning or over in the afternoon * Temperature under the arm (axillary) is usually under of the core body temperature. In adults, the normal range of oral temperatures in healthy individuals is among men and among women, while when taken rectally it is among men and among women, and for ear measurement it is among men and among women. Normal body temperatures vary depending on many factors, including age, sex, time of day, ambient temperature, activity level, and more. Normal daily temperature variation has been described as 0.5 °C (0.9 °F). A raised temperature is not always a<unk> . For example, the temperature rises in healthy people when they exercise, but this is not considered a<unk> , as the set point is normal. On the other hand, a "normal" temperature may be a<unk> , if it is unusually high for that person; for example, medically frail elderly people have a decreased ability to generate body heat, so a "normal" temperature of may represent a clinically significant<unk> . Hyperthermia Hyperthermia is an elevation of body temperature over the temperature set point, due to either too much heat production or not enough heat loss. Hyperthermia is thus not considered<unk> . Hyperthermia is not to be confused with hyperpyrexia (which is a very high<unk> . Clinically, it is important to distinguish between<unk>  and hyperthermia as hyperthermia may quickly lead to death and does not respond to antipyretic medications. The distinction may however be difficult to make in an emergency setting, and is often established by identifying possible causes.
