Most people think of a normal body temperature as an oral temperature of 98.6Â°F (37Â°C) . This is an average of normal body temperatures. Your temperature may actually be 1Â°F (0.6Â°C) or more above or below 98.6Â°F (37Â°C) .
In addition to varying throughout the day, normal body temperature may also differ as much as 0.5 Â°C (0.9 Â°F) from one day to the next, so that the highest or lowest temperatures on one day will not always exactly match the highest or lowest temperatures on the next day.he normal human body temperature is often stated as 36.5â37.5 Â°C (97.7â99.5 Â°F). In adults a review of the literature has found a wider range of 33.2â38.2 Â°C (91.8â100.8 Â°F) for normal temperatures, depending on the gender and location measured.
