A small 2018 study, published in the journal PLOS Medicine, analyzed how 44 college-aged students fared throughout a Boston heat wave in different temperatures. Of the participants, 24 lived in dorms with central air-conditioning set at 71°F, and 20 lived without AC at about 80°F. Over a 12-day period, participants completed two cognition tests daily, which measured their attention, processing speed, cognitive speed, and memory. The results provided evidence that the inside temperature plays a role in brain function: Students living without AC performed 13 percent worse on the arithmetic test than those who did have AC and also gave fewer correct responses per minute by 10 percent, as study co-author Joe Allen, DSc, tells NPR.
The Goldilocks of temperatures that leads to the highest productivity level is 71.6°F.
Those results fit right in with what an earlier study deemed to be the Goldilocks of temperatures—aka not too hot, not too cold (because you can actually be allergic to the frigid air, BTW), but juuust right—that leads to the highest productivity level: 71.6°F.
The 2006 study dug deep into the effect higher temps have on office employees by conducting a meta-analysis on 24 studies that focused on work performance in professional settings. The results showed that when the employees' environment became hotter than the mid-70s in degrees Fahrenheit, their performance plummeted, further indicating that excessive heat really does put a damper on brain function. Using the same cross-examination of studies, then, the researchers were able to pinpoint the best temperature for productivity to be 71.6°F.
