On checking your temperature, you find that your body temperature is 1.5 degrees below normal. Suggest some possible reasons for this situation. Answer: There are several reasons why your body temperature may have dropped. Your body may be losing heat faster than it is being produced. This, however, is more likely to occur on a cool day. Various chemical factors, such as hormones, may have caused a decrease in your metabolic rate, and thus your body is not producing as much heat as it normally would. Alternatively, you may be suffering from an infection that has temporarily changed the set point of the body ʹ s ʺ thermostat. ʺ This would seem to be the most likely explanation considering the circumstances given in the question.
