Histograms demonstrating the grouped T _reg, T _ax-10 s, T _ax-10 min, and T _ty data. Histograms of a T _reg (median = 36.2 °C, skewness = −0.40, kurtosis = 0.51), b T _ax-10 s (median = 36.4 °C, skewness = 0.04, kurtosis = −0.28), c T _ax-10 min (median = 36.5 °C, skewness = −0.66, kurtosis = 0.54), and d T _ty (median = 36.9 °C, skewness = −0.82, kurtosis = 1.02) in healthy young men and women (n = 141). The data for each temperature measurement method was divided into interval widths of 0.3 °C, from 35.1 to 37.2 °C, and less than 35.1 °C and greater than 37.2 °C. T _reg, the regular body temperature each subject reported in the questionnaire, T _ax-10 s, axillary temperature measured with a digital thermometer in a predictive mode (10-s measurement), T _ax-10 min, axillary temperature obtained using a standard method (10-min measurement), T _ty, tympanic membrane temperature by infrared thermometry
