Not Medical Advice: Normal body temperature is around 98.6°F (37°C). An abnormally low body temperature of 94.3°F (hypothermia) can be serious or life threatening. Low temperatures can result from shock, cold exposure, hypothyroidism, diabetes, or a serious infection like sepsis.
The elderly may also have body temperatures that hover around 94°F or 95°F. These people tend to be thin, less active, and lose their body fat. Less fat causes the core temperature of the body to fall and low activity prompts less of an appetite (less eating), which also causes the body to produce less heat.
98.6°F is an average of normal body temperatures. Your normal body temperature can safely rise or fall by as much 1°F depending on how active you are and the time of the day. Following ovulation, women's temperatures can increase by 0.4 to 1.0 degrees.
