The influence of high temperature on the rate of esterification of thiamine in the body was examined by exposing DD-strain mice to hot environment. The treatment did not exert any influence on the content of thiamine phosphate and the rate of esterification in the organs, or the promotion of thiamine metabolism. The findings obtained suggest that the principal cause of thiamine deficiency which is apt to occur in the summer and in the case of exposure to hot environment might be the shortage of thiamine intake through foods due to the loss of appetite and the change of taste at high temperature.
