Exercise (mostly I've seen more intense than walking, but cardio like running, cycling, rowing, etc. - I haven't come across much for resistance training like weightlifting) has been very well studied to improve cognitive ability, as well as mental health (depression/anxiety). Depending on what you mean by proven, it's not gravity, but it's pretty good evidence compared to just about anything in medicine (just look at the numerous citations testing various aspects/study designs/different populations).

Just a few studies (there are countless): https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3951958/ https://pubmed.ncbi.nlm.nih.gov/20065132/ https://pubmed.ncbi.nlm.nih.gov/35153701/ https://ju.se/download/18.4662178a174aa5f82061c573/160103080...

I also read creatine, while used mainly to improve gym perf, helps wirh cognitive ability too.

That's odd. Creatine stores are in muscles. I'm not saying it isn't the case, the body is weird as fuck, but I'd be interested in understanding how that's the case.

It’s because creatine is used by the body to convert sugar into adenosine triphosphate (ATP). ATP is what your body actually uses for energy inside cells for things like contracting muscles and nerve impulses (like in the brain for things such as “thinking”).

ATP can’t be made in the brain, instead it is made by muscles. That’s why exercise and higher levels of creatine are good for cognitive performance and memory.

Wait I don't think this creates the logical connections to validate what he's asking

There are studies on creatine and cognitive performance.

I've been taking creatine monohydrate for years to improve cognitive function. There has been no visible cognitive effect, but it's greatly reduced exercise injuries.

My work performance has increased tremendously since assembling a treadmill desk. The book In Praise of Walking delves into why it works.
