It's entirely reasonable that you've tried napping and found it doesn't work for you, but assuming everyone is the same and therefore napping won't work for anyone is somewhat irrational. Lots of things affect people in many different ways. Napping clearly works for some.

As for suggesting taking a nap isn't "the natural thing to do", what does that actually mean? Nothing modern humans do can be considered "natural" because we've radically changed our environment to the point that it's unrecognisable from anything in nature. There's no such thing as "natural" in an age of electric lighting, computers, processed food, mechanised transport, etc.
