Thermal Work Limit (TWL) is a heat stress index that estimates the maximum sustainable work rate a worker can perform without exceeding safe physiological limits.
TWL considers multiple environmental factors:
Air temperature Humidity Radiant heat Wind speed (critical factor)Also considers:...
Chemical reactions in every cell are optimal at 37°C
