Harvard researchers say heat waves hamper your ability to think quickly and clearly.<br />In 2016, study researchers tested the mental performance of 44 students during a heat wave in Boston.<br />Half of the students were placed in newer dorm buildings with central AC, while the other half lived in older dorms without it.<br />Over 12 days, researchers had participants take cognition tests on their phones immediately after waking up.<br />The students living without AC took 13% longer to respond to questions, and their answers were 13% less accurate.<br />Results indicate that even if high temperatures don't pose immediate threats to someone's health, they can impair them.
