Calculations regarding the Required Sweat Rate Index (Table 5) show a risk for an excessive increase in internal body temperature in all three companies.
The Sweat Rate Index was calculated according to the NTP 350 (based on ISO 7933) using climate variables from the least favorable (highest 'high' WBGT) day in order to predict the evaporation, sweat, and humidity conditions necessary to avoid risk.
The present study demonstrates deficiencies in the Sweat Rate Index (specifically that it recommends restrictions that are impractical or impossible to implement) that could be improved through modifications of the index or implementation of new methodologies.
Both the Sweat Rate Index and the WBGT standards have been criticized as being overprotective of acclimatized workers in tropical climates (14) and in conditions where mean radiant temperature exceeds dry air temperature (15).
The Required Sweat Rate Index as applied in this study demonstrated conditions of concern since, according to this system, workers should only be allowed to work approximately 15 min, 13 min, or 24 min of every hour in Companies A, B, and C, respectively, on the days with the highest WBGTs registered.
Wet bulb globe temperature (WBGT) variables were measured with a heat stress meter and threshold value limits and the Sweat Rate Indexes were calculated for each workplace.
Sweat gland innervation index (SGII) was quantified with a new computerized area-based morphometric system.
Recently, we have developed a new morphometry-based method to quantify the pathology of sudomotor innervation on skin biopsies according to the parameter of sweat gland innervation index (SGII) (14).
Meanwhile, the Nasdaq Composite Index sweated off more weight as investors questioned record-high prices for technology and Internet-related stocks.
He reported no fever, sweats or weight loss (body mass index, 22.9 kg/m).
