The temperature is low below 38℃ and high above 39℃. The normal body temperature is not more than 37℃ on the oral surface and 37.6℃ on the anal surface. Oral thermometer is a thermometer for measuring oral temperature. The normal body temperature of children is higher than that of adults, which is easy to fluctuate.
Generally speaking, the normal body temperature of children is about 37.37 2℃, and the maximum body temperature of a few children can reach 37.4℃ a day. In addition, the child's body temperature will fluctuate greatly in one day. The temperature difference of children in one day can reach 0.5 ~ 1℃, and that of older children can reach 1℃ or above. After meals, exercise, bathing, crying, sweating and hot weather, the body temperature is higher in the afternoon. In contrast, the body temperature is lower in the morning and during sleep.
Extended data:
Higher vertebrates such as birds and mammals have gradually developed the function of body temperature regulation, which can keep the body temperature relatively constant in different temperature environments. These animals are called warm-blooded animals or warm-blooded animals. There are also some mammals, such as hedgehogs, which are between the above two animals. In warm seasons, the body temperature can be kept relatively constant; In the cold season, the body temperature drops and hibernates.
People standing still and running to keep warm in cold weather are all such adjustments. Humans can increase or decrease clothes according to different environmental temperatures, and create an artificial climate environment to get rid of the summer heat and keep out the cold, which can be regarded as a more complicated behavior regulation.
