The brain, like a muscle, requires challenges to grow but also has limits that need acknowledging. Cognitive tasks, such as solving puzzles, accumulate 'residue' akin to muscle fatigue. Research from the Paris Brain Institute shows that intense mental effort raises glutamate levels in the brain, indicating fatigue and the need for rest. This reflects that cognitive work not only demands effort but can lead to a state similar to physical exertion. Balancing productive challenge with recovery is essential for cognitive mastery and health.
“True mastery comes from balancing productive strain with recovery.”
“The brain has its limits. One of the greatest pursuits a curious person can undertake is learning how to push those limits farther, without breaking them.”
