Twenty-two undergrads lived in air-conditioned brick-based buildings while the other 22 lived in similar type buildings with no air conditioning.
Scientists added that the buildings the students lived in made the effect of heat on their brains even worse.
“These buildings have a hard time shedding heat during hotter summer days created by the changing climate, giving rise to indoor heat waves,” study co-author Joseph Allen told KDKA in a press release.
Those living in the buildings without air conditioning performed more than 13 percent worse on math and memory tests than their cohorts who lived in air-conditioned dorms.
“Most of the research on the health effects of heat has been done in vulnerable populations, such as the elderly, creating the perception that the general population is not at risk from heat waves,” Jose Guillermo Cedeño-Laurent, the study’s lead author said in the release.
