What is the belief behind why I feel better after burning sage and getting rid of bad energy?

Whenever I burn sage, I actually feel lighter and calmer, almost like a fog lifts off my mind. But I’ve always wondered why that happens. Is it just psychological, or is there really something about sage that removes bad energy from my aura and space? I want to understand the deeper belief behind it — why people, including me, feel such a strong shift after cleansing with sage.
