Personal warning temperature (PWT)
The Personal Warning Temperature (PWT) is a method of determining a person's personal warning temperature that defines a fever for that person. The method includes analyzing a person's body temperature measurements taken over time when the person is healthy, in order to find the person's average temperature; standard deviation; a channel defined by an upper and lower temperature bound using the average and standard deviation, and a selected multiplier for the standard deviation, such that nearly all body temperatures fall within the channel; and a personal warning temperature similarly defined using the average, standard deviation, and another selected multiplier for the standard deviation. The method also determines a correction or interpretation of a person's body temperature based on the time of day to account for known variations associated with circadian rhythm. A person can use their personal warning temperature for improved and accelerated awareness of their health status.
