Frequently, the physiological burden of crop production is overlooked while workers are in the fields. We completed a mixed-methods study using a cross-sectional survey among migrant and seasonal farmworkers about their experience with HRI symptoms (\n                    <jats:italic toggle=\"yes\">N<\/jats:italic>\n                    = 148) and conducted an intensive surveillance on a smaller group of workers (\n                    <jats:italic toggle=\"yes\">N<\/jats:italic>\n                    = 20) in field trials (\n                    <jats:italic toggle=\"yes\">N<\/jats:italic>\n                    = 57 trials) using a chest-strapped multi-parameter monitoring wearable sensor (MPMWS) that measured skin\/body temperature, heart and breathing rate, kilocalories burned per hour, and provided a physiological intensity (PI) score. The field trials were conducted across three classes of climate conditions and three PI score categories. We found that those in the uncomfortable category (PI score &gt; 4.0) had a statistically significant (\n                    <jats:italic toggle=\"yes\">F<\/jats:italic>\n                    ratio = 16.41,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    &lt; .001) higher body temperatures (\n                    <jats:italic toggle=\"yes\">M<\/jats:italic>\n                    = 100.05\u00b0F) than those with a mild PI (range = 0-5) score \u2a7d 2.5 (\n                    <jats:italic toggle=\"yes\">M<\/jats:italic>\n                    = 99.56\u00b0F) or moderate PI score &gt; 2.5-4 (99.84\u00b0F).
