Thiamine concentration in the sweat and blood, and its daily urinary excretion were estimated with 6 healthy male students exposed to hot environment (42-43℃, 100% humidity) for about 30 minutes. Average thiamine content of 0.24 μg/dl in the sweat indicates that the excretion of the vitamin in the sweat is extraordinary low. The thiamine concentration in the sweat varied with that in the blood plasma. No definite tendency could not be observed in the urinary thiamine level as well as in the urinary excretion of the vitamin in case of the exposure to hot environment. This finding shows that the exposure to hot environment might not promote the excretion of thiamine in the urine.
