What's the main difference between "fresh" and "refresh?" Or are they interchangeable?

"Fresh" means something that is new, recently made or harvested, while "refreshed" means something that has regained freshness, or energy. Ex: In the morning when I wake up, I feel fresh, and in the afternoon, I take a nap to refresh myself. Ex: The vegetables are fresh from the garden, I'll put them in some cool water to refresh them before cooking them.
