Lately I've been hitting a ceiling of fatigue after studying for about 4 hours (with breaks in-between where I go on a short walk, eat a meal etc). After I feel super burned out, like there is nothing left in my brain to give. There are days where I have a bit more mental energy, but I still will hit a limit at these days after maybe 5-6 hours. I guess it's normal to feel exhausted after mental exertion but I really want to know:
1) What is the mechanism behind brain fatigue? Excess serotonin, acetylcholine? Depletion of glycogen and/or ATP?
and
2) What to do about it, so how to stretch the amount of time I can focus intensely? There are obviously people that can work 10+ hours a day on mentally challenging tasks, and I'd love to be one of them (or get closer to their capacity at least).
Please give me all your recommendations to help reenergize the brain. Everything is fair-game, from lifestyle and diet advice, to legal and illegal supplements, drugs and hormones.
Cheers!
