what is the normal body temperature
Body temperature norms. Normal body temperature varies by person, age, activity, and time of day. The average normal body temperature is generally accepted as 98.6Â°F (37Â°C). Some studies have shown that the normal body temperature can have a wide range, from 97Â°F (36.1Â°C) to 99Â°F (37.2Â°C). A temperature over 100.4Â°F (38Â°C) most often means you have a fever caused by an infection or illness.
