Heatwaves Can Affect One's Ability to Think and
Make Decisions New research says heatwaves hamper your ability to think quickly
and clearly. For the study, researchers at Harvard tested the mental performance of 44 students during a heatwave in Boston
in 2016. Half the students were placed in newer dorm buildings with central AC, while the other half lived in older dorms without it. Over 12 days, researchers had participants take cognition tests on their phones immediately after waking up. The students living without AC took 13% longer to respond to questions, and their answers were 13% less accurate. Results indicate that even if high temperatures don't pose immediate threats to someone's health, they can impair them.
