Aerobic exercise. Maybe too obvious and not crazy enough?
Totally anecdotal and subjective, but the year I started ultrarunning I felt that I had gotten a pretty sudden cognitive boost. It felt like more oxygen was flowing to the brain; not groundbreaking but noticeable.
I could attest to this! Had the same experience doing multi year marathons..
