Toward health or toward improving one's health and wellbeing.
From 'health' plus '-ward', a directional suffix meaning 'toward' or 'in the direction of' (from Old English 'weard'), found in words like 'forward' and 'backward'.
The '-ward' suffix gives us directional adverbs, and 'healthward' literally means moving in the direction of better health—it's rarely used today but shows how Old English spatial thinking (toward/away) got applied to abstract concepts!
