Possibly. I don't know why not. Aunt Clair has indicated (if I remember correctly) that energy inflow is in the insoles and outflow is on the heels, so if you're 'lying in the 'tanning' machine', the 'dirty' energy could come out that way. Robert's 'baloon breathing' works in a similar way (but without the 'machine') only the 'dirty' energy goes out on the outbreath of the mouth.
