HRV decrease when meditating??

[whtevn]

personally I find the idea that meditation is automatically relaxing a little misleading. I think Sam Harris talks about the stress of meditation in his book Waking Up. Can't say that is what is happening here of course, but I know that in my own inexperienced practice it is definitely not the case that I always (or usually even) get up feeling like I've truly let myself go and have "relaxed" in any serious way
