You think meditation is relaxation, you do not realise how much effort it takes. I'd suggest finding a tutorial and trying even 5 minutes.

As for the "sprinkle of woo", some meditation practices comes with buckets of foo, while some are entirely woo free.

I've done this for an hour or so on occasion. I don't find it a particular strain. I may be doing something different than what you are doing, though.

The point is not that it's a particular strain. The point is that most people can't just sit back and let their mind go - to maintain focus requires concentration, and concentration is not "free" - it takes energy. It may feel energising - especially after you're done -, the same way exercise does, but people who think that meditation is "just relaxation" usually have no idea what is involved.
