What if regular exercise is the best cognitive exercise?
At the risk of sounding to newage-y, I experience the benefits of exercising as energy balancing.<p>Solving problems, learning and building new things all day can be very mentally exhausting. Cardio, sports, lifting; helps re-balance the physical with the mental. I am sure there are more scientific words and biological descriptions that I lack the vocabulary for. If I get too mentally focused on a project/job/problem and go days without matching it with vigorous physical activity, I end up not sleeping as well, am less tolerant, more scattered and brain fog tends to start rolling in. If I counter it with the physical exercise or physical energy expenditure the mental clarity comes back, I sleep better, and don't have hair-triggered verbal impulse control issues. Otherwise, if I let it go for too long, lethargy sets in - which I attribute to the body/physical and mind/mental trying to rebalance itself. I dont think it cares that it makes me feel like crap overall, more that it's neutral in just wanting a balance however that comes about.<p>I often refer to exercise as me taking care of my mental health - as opposed to being physically fit. That could be seen as "exercise [being] the best cognitive exercise". Looking at it that way, exercise creates a mental-out imbalance, which causes the stored energy in the mind to be stimulated and need more output creating the mental sharpness. Obviously I have nothing to back up the claims other than decades of experiencing this to be <i>true for me</i> time and time again; though I do believe there are better biological explanations than <i>energy</i>.
