Beebop said:So what is the mechanism that cortisol uses to reduce brain fog? I know this is a process that is not helpful over the long-term, but maybe it's worth understanding.
Having mental clarity would help us survive in a life threatening situation so it makes sense that cortisol would promote that. But how?
My understanding is that stress hormones helps to raise temperatures and your brain benefits from it. And indeed, if I become incredibly stressed (say an exam) then my brain doesn't do too bad, but its short lived and probably not as good as if the brain was working well from a healthy metabolism.
Actually getting those stress highs were the only reason I was successful during my studies and work, otherwise I was a lethargic piece of wood. When the adrenaline kicked in, I finally could do things and I was thankful for the stress. Its only after reading RP that I understood it wasn't healthy and my body can't continue working just on stress highs.
