Colder temperatures help people think clearly. Research shows that people perform tasks better when the room temperature is set at a cooler setting than a warmer one. What’s more, other research shows that people are less inclined to tackle cognitive problems in the summer, as opposed to winter, because the summer uses more glucose that’s needed for mental processes. So, getting outdoors for a brisk walk to a local coffee store in the wintertime could give you your next big idea for a work presentation.
