I do not think it means what you think it means.
Whenever you become anxious or stressed, outer purpose has taken over, and you have lost sight of your inner purpose. Your state of consciousness is primary. All else is secondary.
For a room with a heart, I assume you can only heal upon entering (not starting your turn there), just like picking up a token from a room. Correct?
From the rules:
"Fountain of Healing — When you enter a room
with a Fountain of Healing, heal 1 damage."
