Body temperature may be abnormal due to fever (high temperature) or hypothermia (low temperature). A fever is indicated when body temperature rises about one degree or more over the normal temperature of 98.6 degrees Fahrenheit, according to the American Academy of Family Physicians. Hypothermia is defined as a drop in body temperature below 95 degrees Fahrenheit.
Normal Body Temperature. Body temperature is usually measured by a thermometer placed in the mouth, the rectum, or the auditory canal (for tympanic membrane temperature). The normal oral temperature is 37Â° Celsius (98.6Â° Fahrenheit); rectally, it is 37.3Â° Celsius (99.2Â° Fahrenheit).The tympanic membrane temperature is a direct reflection of the body's core temperature. These values are based on a statistical average.. Hypothermia is a condition in which an organism's temperature drops below that required for normal metabolism and function. For people in stage 1 hypethermia, body temperature drops by 1-2Â°C below normal temperature (35-36Â°C).
