The Composition of Sweat, with Special Reference to the Vitamins*
نویسندگان
چکیده
Knowledge as to the composition of sweat is as yet fragmentary and many points are subject to dispute. Reasons for this are numerous, some of the more obvious being the difficulty of making satisfactory collections, variation in composition of sweat elaborated by different regions of the body, and the fact that exploratory work cannot be done on animals. The subject assumes considerable importance, however, when it is realized that in the tropics and hot deserts sweat production may amount to 5 to 12 liters a day (Dill (8) and Dill et al. (9)) and that this sweat is by no means a simple excretion of a dilute salt solution. If vitamins are lost in sweat, as has been claimed recently, there is a possible basis of support for such claims as that of Mills (22) that vitamin requirements are elevated in hot climates. This paper is a report on the composition of sweat with special reference to vit,amins and some organic substances and to variations in composition of sweat collected from different parts of the body and at different times. Great care was taken in the sampling procedures and in the analytical methods used.
