Basic Thermal Distribution for the Hand of Ordinary Persons

Our experiences in temperature measurements on the hand surface during relaxation have shown that some persons have high temperatures in the center of their palm and others have high temperatures at their thenar eminence and hypothenar eminence. This paper reports on a relationship between hand temperatures and patterns of 2-dimensional thermal distribution on the hand surface of 81 ordinary persons during relaxation. Differences in patterns of 2-dimensional distribution show all data can be classified into four groups:1) high temperature in the middle of the palm; 2) high temperature at both eminences; 3) intermediate type; 4) combination type. Hand temperatures differ for the types, but not for sex and age.
