14. A method of measuring hydration of a subject comprising the steps of:
-
a. measuring an initial core body temperature of the subject; b. measuring a subsequent current core body temperature of the subject; c. subtracting the initial core body temperature from the subsequent core body temperature; d. multiplying by the subject'"'"'s weight; and
,e. dividing by a factor of ambient compensation. - View Dependent Claims (15)
