[Work in very hot, dry climates: evaluation of stress and procedures for reducing strain on the human body].

Even in temperate zones of the earth such as Middle Europe quite a number of men have to work in very hot dry climates, particularly in salt mines. Problems of evaluation stress under these condition are discussed. Climatic chamber experiments at ambient temperatures mainly between 45 and 65 degrees C were performed in order to find out various possibilities to reduce heat strain. New methods are discussed for reducing extremely elevated body core temperatures.
