What if you could control your blood sugar levels with your mind? A new study suggests that you can—just not consciously, Ars Technica reports. Researchers instructed type 2 diabetics to play video games in a room for 90 minutes, along with a clock that ran faster, slower, or the same speed as actual time. Asked afterward, those in the room with the “slow” clock (which had a 45-minute delay) thought less time had passed—and their blood sugar dropped about half as quickly as those in the “fast” room (which had a clock that ran for 180 minutes), the researchers report this week in the Proceedings of the National Academy of Sciences. The results highlight just how much power our minds have over our bodies. And the researchers say that this power could even lead to novel strategies—like mindfulness meditation—for dealing with the effects of diabetes.
