Brief Summary: Extreme heat events are a significant global threat to health and wellbeing and result in more morbidity and mortality than all other natural disasters combined Thus a key priority is identifying effective and accessible heat resilience solutions to protect individuals from the potentially fatal consequences of heat stress Within a range of ambient conditions a fan has been recognized a low-cost heat resilience solution However when ambient temperatures exceed skin temperatures eg above 35C a fan will incur greater dry heat gain which may be counterbalanced with evaporation of sweat from the skin surface However at a critical indoor temperature the rate of heat gain will exceed the rate of evaporation resulting in net heat gain The critical indoor temperature has yet to be determined The purpose of this present study is to identify the indoor temperature at which a fan results in greater cardiovascular and thermal strain relative to still air in young adults using a simulated heat wave scenario of a warming room
