Brief Summary:
With the increasing incidence and severity of extreme heat events accompanying climate change there is an urgent need for sustainable cooling strategies to protect heat-vulnerable older adults who are at increased risk of adverse health events during heat stress Health agencies including the World Health Organization the United States Centers for Disease Control and Prevention and Health Canada currently recommend visiting a cooling centre or other air-conditioned location for 1-3 hours per day during extreme heat events to mitigate hyperthermia and strain on the cardiovascular system and therefore the risk adverse health events However our recent trial shows that while brief air-conditioning exposure is effective for reducing body temperature and cardiovascular burden in healthy older adults the physiological impacts of cooling abate quickly following return to the heat The purpose of this project is therefore to assess whether shorter but more frequent air-conditioning exposure provides more effective cooling than current recommendations a single 1-3-hour cooling bout in older adults with or without common chronic health conditions associated with increased vulnerability to extreme heat This will be accomplished by evaluating physiological strain in older adults with and without diabetes andor hypertension exposed for 8 hours to conditions reflective of extreme heat events in temperate continental climates 35C 60 relative humidity Participants will complete 3 separate simulated heat event exposures i a control trial no cooling throughout the 8-hour heat event ii a recommended cooling trial 3 hours of heat exposure followed by 2 hours cooling and iii a hybrid cooling trial 2 hours of heat exposure followed by 1 hour cooling another 2 hours heat exposure followed by 1 hour cooling and a final 2-hour heat exposure
