According to Dr Parsonnet, the normal human body temperature is not 98.6°F. Based on a study done by her, the body temperature depends on age, gender, weight, time of the day, etc. Since the last 200 years, the normal human body temp has been cooling down. Certain evidence shows that the fall is true and is not because of the difference in thermometers. This temp fall is not new to us, it is happening since the industrial revolution
