Yep, mental exhaustion is undoubtedly a thing! I'd love to see how heart rates change with something like test question difficulty. Since sweat is generally a product of heat and occurs when your heart works harder during exercise, I wonder if the heart also works harder to pump the brain with more oxygen to enable it to... think harder? Obviously just musing, am no physiology expert. |
