"My studies showcase special emphasis on cumulative recursive [permutative?] effects of one's hydration, nutrition, self-image, and general cognitive ability."
Basically, each of the four items affects any number of the others, which in turn affects any number of its others...
I would like to describe that each one has an effect that continuously affects the way that one or more or all the others affect it and each other one, which in turn again further ....
recursive permutations seems about right, but I would love to describe the subject 'effects' with a variation of 'permutations' used with 'recursive' as well.
Any ideas?
