abstract: George Havenith, Dusan Fiala. Thermal Indices and Thermophysiological Modeling for Heat Stress. Compr Physiol 2016, 6: 255-302. doi: 10.1002/cphy.c140051 Corrections have been made to properly spell out the acronym PHS in two places in the article. The error was introduced during the copyediting process. On page 264, "which led to a new version of the standard, the Public Health System (PHS)" was corrected to "which led to a new version of the standard, the predicted heat strain (PHS)." On page 288, "PHS. To mitigate the adverse health effects…" was corrected to "Public health system. To mitigate the adverse health effects…."
