Why not? Many of us feel sort of guilty if we just get really comfortable and give ourselves permission to just rest and relax “on purpose” yet it is so healthful and something that all of us here in the west need so much more of. We may think we are resting by flopping on the couch and turning on the tv after work etc (and that’s fun too ) but to really let go…to turn off that fight or flight and to allow ourselves to switch from sympathetic nervous system dominance over to parasympathetic (the rest and digest wing of our nervous system) aka triggering the Relation Response as Herbert Benson M.D. coined in his 1975 book “The Relaxation Response” is something that we not only all need, but it is also a skill that needs to be learned by many of us and why Savasana is so important after a yoga class (and any other time you get the chance). Did you know that letting go on that very deep level is 80% of the value of real sleep? You owe it to yourself to “do less”. If you are worried about the time, set a timer, and if you fall asleep it only means that you are tired (as most of us are whether we are aware of it or not). Your props don’t have to be fancy. Mine sure aren’t. You can always improvise with books, pillows, cushions off your couch and rolled up blankets for bolsters. Just do it and allow yourself to restore. Don’t feel like pulling out a bunch of props?(although I highly recommend it) Just stretch your legs up the wall. It’ll be one of the best things you’ve done for yourself  in a while. You deserve it.
