monitoring basis at US military training camps and became widespread for the use
in workplaces and sports training facilities all over the world. It is suggested in the international standard
ISO 7243, OSHA (US Occupation Safety), Japan Society for Occupational
Health and the SMA (Sports Medicine Australia) in establishing the permissible
heat exposure limits in health, sports or other physical activities.
