A temperature of 99.8 degrees Fahrenheit (37.7 degrees Celsius) is slightly above the normal range of body temperature, which is typically considered to be between 97.7 and 99.5 degrees Fahrenheit (36.5 and 37.5 degrees Celsius) for most adults.
However, whether a temperature of 99.8 is normal or not may depend on various factors, including the age, health, and activity level of the individual. In some cases, such as after exercise or in response to a minor illness or infection, a temperature of 99.8 may be considered within normal limits.
It is important to note that temperature is just one indicator of health, and other symptoms or factors should be taken into consideration when assessing overall health. If you are concerned about your temperature or any other symptoms, it is always best to consult with a healthcare provider.
