Category, where to take measurements, when to make measurements, notes:

• Mouth temperature: Let the thermometer be set under the tongue for 2~3 minutes, but this kind of measurement is prohibited to nurslings and those who will not cooperate, and must be allowed a lead time of 30 minutes for those who have just swallowed down hot or cold beverage.
• Armpit temperature: Wipe the armpit clean and hold clasped there for 2~5 minutes.
• Anal temperature: Lubricate the anus with Vaseline before insertion up to 3~5 cm into the anus for 2~3 minutes, this kind of measurement prohibited to those suffering from diarrhea or receiving chemical treatment and the newly born.
• Ear temperature: With the head immobilized, the ear way drawn straight, insert the thermometer into the ear way for 1~2 seconds, for those aged above 3 the ear should be pulled upwardly reawards.

The normal range of body temperature is 36~37.5 measured orally, 36.5~38 anally, and 35.5~37 in the armpit, in degrees Celsius. Body temperature will change as a function of activities, a change in ambient temperature and of the physiologic clock as well, the physiologic clock has it that the highest level of body temperature occurs shortly before nightfall and the lowest level comes in midnight or on daybreaking moment; with females the body temperature is higher prior to oval secretions, and, due to physiologic clocking, the amplitude of change in body temperature is greater than in the male case. For younglings and older people the body temperature is easily vulnerable to impacts due to ambient temperature, so they should be especially concerned about changes in weather conditions, on the infant side, with their body surface and subdermal fats being rather thin, that would lose heat sooner; and with their heat diffusion faculty not yet fully developed, the wouldn’t be able to release excess heat if exposed in an excessively hot environment, and would come off to an elevated body temperature. With older people, however, degraded metabolism, blood circulation and want of facility to conserve heat make them inept in responding to any fluctuation in ambient temperature condition.
