A review of heat stress research with application to forestry.

Heat is a work factor faced by many forest workers all over the world, and yet grossly neglected by ergonomic research in forestry. This review of heat stress research which focusses on its applicability in forestry concluded that (a) the accuracy of the two ISO heat stress indices has to be considered in the light of the accuracy of the suggested work load determination methods, (b) dehydration studies are highly desirable for forestry, and (c) a standard research method to determine comfort of protective clothing is required. Further areas reviewed were heat stress studies on self-pacing, work/rest schedules and performance.
