In the second summer season, both arms will have air conditioning units, but those in the year two distribution arm (B) will receive an electricity subsidy, while those in the year one AC distribution arm (A) will not, allowing researchers to assess the effect of an electricity subsidy.\n\nParticipants will be randomized to receive an air conditioner and financial support for electricity costs in either the first summer season or the second summer season of the study.\n\n* Heat stress, heat strain, mental health, and healthcare utilization will be assessed via participant survey.\n* Air conditioner utilization will be assessed via continuous load monitoring devices.\n* Indoor air temperature will be assessed via continuous data loggers.",[84,85,86,87,88,89],"Hot Weather; Adverse Effect","Heat Effect","Heat Stress","Heat Stroke, Heat Exhaustion","Heat Exposure","Heat Strain",[91,92,93,94],"Cooling","Air conditioner","Heat related illness","stepped wedge","2026-01-21",{"date":97,"type":98},"2026-01-22","ACTUAL",{"date":100,"type":98},"2025-05-19",{"date":102,"type":78},"2026-10-15",{"name":5,"class":6},1]
