In this study, we collect real-time weather and physiological data using a wearable computing platform from 100 rickshaw pullers in Dhaka, Bangladesh. In parallel, we interview 12 additional rickshaw pullers to explore their knowledge, perceptions, and experiences related to climate change. We propose a Linear Gaussian Bayesian Network (LGBN)-based regression model that predicts key physiological biomarkers based on activity, weather, and demographic features. The model achieves normalized mean absolute error (NMAE) of 0.82, 0.47, 0.65, and 0.67, respectively, for the biomarker: skin temperature, relative cardiac cost, skin conductance response, and skin conductance level. Using climate model projections from 18 CMIP6 global climate models, we layer the LGBN on top of future climate forecasts to conduct a survivability analysis for both current (2023-2025) and future years (2026-2100). Based on the criteria\n                    <jats:italic toggle=\"yes\">\n                      T\n                      <jats:sub>WEGT<\/jats:sub>\n                    <\/jats:italic>\n                    &gt; 31.1\u00b0 C and\n                    <jats:italic toggle=\"yes\">\n                      T\n                      <jats:sub>skiin<\/jats:sub>\n                      &gt;\n                    <\/jats:italic>\n                    35\u00b0C, the analysis shows that a significant percentage of rickshaw pullers (32%) are already facing a high risk of heat-related illness or prolonged exposure to extreme heat\n                    <jats:italic toggle=\"yes\">\n                      (T\n                      <jats:sub>WBGT<\/jats:sub>\n                      &gt;\n                    <\/jats:italic>\n                    31.1\u00b0C) during regular work hours.
