Sounds commonsensical since my mom always said things like "you're depressed because you're just sitting there, go outside more!" And she was usually right. But..I know a bunch of busy workaholics who are pretty depressed, if you go by alcoholism and self-hatred. And when you say "the right amount and type of sensory stimulation at the right time" it sounds like you're just saying "the cure for depression is to find something to do that'll cure your depression," unless you've got a sharper idea of what you mean.
