Heat's impact on economic growth and aggregate productivity is well-established, but while individual impairments are well-understood as mechanisms, the role of interpersonal dynamics remain unexplored despite the growing prevalence of team-based occupations. In our experiment, programmers were randomly assigned to work individually or in pairs under warm (29°C) or control (24°C) conditions. We found that heat had no effect on individual performance but impaired team performance - not through decreased effort but likely through impaired collaboration. This negative impact was strongest in heterogeneous teams, suggesting heat exacerbates coordination challenges, confirmed by poorer partner evaluations in warm conditions.
