From @english.lemonde.fr (paywalled): "To avoid overheating from the electrical activity of thought, [the brain] deliberately downgrades certain cognitive functions." 😱 www.lemonde.fr/en/environme...

"Losses of control and concentration can be explained by a defense mechanism in the brain, which tries to protect itself from heat. Trapped inside a box with no ventilation system, the brain has to struggle to maintain its optimal operating temperature. To avoid overheating from the electrical activity of thought, it deliberately downgrades certain cognitive functions. It cannot stop the heart, blood circulation, or a basic level of awareness of our immediate surroundings. So, it downgrades everything else."
