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: Oral (under the tongue): ()〔 Internal (rectal, vaginal): 〔 Different parts of the body have different temperatures. Rectal and vaginal measurements taken directly inside the body cavity are typically slightly higher than oral measurements, and oral measurements are somewhat higher than skin measurements. Other places, such as under the arm or in the ear, produce different typical temperatures.〔 Although some people think of these averages as representing the normal or ideal temperature, a wide range of temperatures has been found in healthy people.〔 The body temperature of a healthy person varies during the day by about with lower temperatures in the morning and higher temperatures in the late afternoon and evening, as the body's needs and activities change.〔 Other circumstances also affect the body's temperature. The core body temperature of an individual tends to have the lowest value in the second half of the sleep cycle; the lowest point, called the nadir, is one of the primary markers for circadian rhythms. The body temperature also changes when a person is hungry, sleepy, sick, or cold. ==Methods of measurement== Taking a person's temperature is an initial part of a full clinical examination. There are various types of medical thermometers, as well as sites used for measurement, including: * In the anus (rectal temperature) * In the mouth (oral temperature) * Under the arm (axillary temperature) * In the ear (tympanic temperature) * In the vagina (vaginal temperature) * In the bladder * On the skin of the forehead over the temporal artery 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Human body temperature」の詳細全文を読む スポンサード リンク
