AB  - Recent studies have characterized individually experienced temperatures or 
      individually experienced heat indices, including new exposure metrics that 
      capture dimensions of exposure intensity, frequency, and duration. Yet, few 
      studies have examined the personal thermal exposure in underrepresented groups, 
      like outdoor workers, and even fewer have assessed corresponding changes in 
      physiologic heat strain. The objective of this paper is to examine a cohort of 
      occupationally exposed grounds and public safety workers (n = 25) to characterize 
      their heat exposure and resulting heat strain. In addition, a secondary aim of 
      this work is to compare individually heat index exposure (IHIE) across exposure 
      metrics, fixed-site in situ weather stations, and raster-derived urban heat 
      island (UHI) measurements in Charleston, SC, a humid coastal climate in the 
      Southeastern USA. A Bland-Altman (BA) analysis was used to assess the level of 
      agreement between the personal IHIE measurements and weather-station heat index 
      (HI) and Urban Heat Island (UHI) measurements. Linear mixed-effect models were 
      used to determine the association between individual risk factors and in situ 
      weather station measurements significantly associated with IHIE measurements. 
      Multivariable stepwise Cox proportional hazard modeling was used to identify the 
      individual and workplace factors associated with time to heat strain in workers. 
      We also examined the non-linear association between heat strain and exposure 
      metrics using generalized additive models. We found significant heterogeneity in 
      IHIE measurements across participants. We observed that time to heat strain was 
      positively associated with a higher IHIE, older age, being male, and among 
      Caucasian workers. Important nonlinear associations between heat strain 
      occurrence and the intensity, frequency, and duration of personal heat metrics 
      were observed. Lastly, our analysis found that IHIE measures were significantly 
      similar for weather station HI, although differences were more pronounced for 
      temperature and relative humidity measurements. Conversely, our IHIE findings 
      were much lower than raster-derived UHI measurements. Real-time monitoring can 
      offer important insights about unfolding temperature-health trends and emerging 
      behaviors during thermal extreme events, which have significant potential to 
      provide situational awareness.
