Heat vs. Men

According to investigations made by the Pittsburgh Experiment Station of the U. S. Bureau of Mines, a man in a state of rest and in still air cannot endure indefinitely a temperature higher than 90DEG F. with 100% relative humidity. Stout men subjected to uncomfortably hot temperatures lose more weight than thin men, but, as a rule, can stand high temperatures longer and complain less of exhaustion.

It was found that the chief cause of irritation to the eyes of people working in conditions where the heat is extreme is the perspiration that gets into the eyes from the face and forehead.
