What are the benefits of cleansing my house with sage after a Reiki session?

A few friends burn sage in their homes regularly and say it makes them feel calm and peaceful. I’m curious—apart from tradition, what are the actual benefits of saging a house, especially after something like a Reiki session? Does it really shift the energy, or is it mostly about the ritual itself? I want to know what people who do this regularly experience.
