One of the things I learned from researching sleep in preparation of becoming a parent is that sleep is sleep. Rest is not sleep. To get the benefits of sleep, you have to sleep.
Resting does give you benefits, but they are not those of sleep. You cannot replace sleep with rest and expect anything comparable. I don't remember the primary source but I do know it was emphasised in sleep management policies in military contexts.
That said, I agree with your overall theme. Get some relaxation and don't worry so much about the sleeping. It takes training to learn how to nap, especially in the high-stimulus environments of today. But if you stress over sleep, well, that surely won't get you to sleep!
