Your Brain Has Its Own Thermometer, and It Prefers 77 Degrees
People in some cultures around the world put a priority on mid-day naps and “siestas” . . . especially in the summer . . . and now, there may be some science to explain why that’s actually GOOD for productivity.
Neurobiologists from Northwestern University have studied the brains of FRUIT FLIES . . . and they say the brain has its own thermometer, and that it prefers 77 DEGREES.
Temperatures above that, for prolonged periods of time, may cause the brain to trigger a desire for SLEEP or rest. Again, they observed that in fruit flies.
If they were looking at just human brain cells, some of that desire might be learned cultural or behavioral tendencies. But the fruit flies do not have a cultural tradition of siestas . . . and the researchers believe that fruit flies’ brain cells operate similarly to human brains.
They’re including these findings in a larger study on how temperature affects brain power. They previously did research into why it’s harder to get out of bed on colder mornings . . . that’s something that fruit flies ALSO experience.
