A, a curtain is used to screen you off, and if it's a very cold day we've got infra-red heat  we've got a lamp above the he , the couch and  we actually put on the infra-red heat so we warm you up first before you start, before we start  so your body is feeling nice and warm and you're feeling relaxed, we have nice music playing and it does help  right, with the tension that builds up on the shoulders.
