You know sleep labs, where people come to be studied for sleep disorders? Couldn't you give people a recording box and some electrodes or sensors to do those sleep tests in their own homes and beds? It seems odd that there tests can only be done in a lab where people won't sleep normally anyway. I can't help but think that must be skewing the results.
