Since we now know that some people can change their heart beat at will, their body temperature or their immune system response, and that it's something you can train, I don't think anybody find that very surprising. But good to know.

I don't think anyone can control their heart muscle directly, but rather through meditation calm themselves and then their heart slows down. And body temperature is not controlled by a muscle so that is probably meditative as well. No comment on the immune system part.

I was once asked what drugs I had taken, which confused me because I had taken none. A mirror inspection revealed that my pupils were hella dialated, for no apparent reason. "On command" seems a plausible stretch from "spontaneously for no reason."

Hm, not really.

There are several reasons why you might have involuntarily diluted pupils, e.g. arousal, i.e. triggering a entirely natural response to a stimulus, even if it the stimulus is aehm "imaginary"/a thought (thinking about the sun).

This is called indirect control in the posted article.

Having voluntary control over your pupils is something entirely different, and just because you have dilated your pupils "by accident" doesn't mean your short of controlling them.

Is there any actual differece to a muscle if you think about it and it happens?

And some can see a fappilion more colors than the rest (terrachromats), and now COVID has caused some people to lose their sense of smell.. :(

Maybe in the future we’ll have to target products and services for wildly different human hardware just as we have to do now for age, sex, computers etc.

I'd consider "controlling" something to be more direct, but that's semantics I guess.

If I heard "control heartbeat", I'd think more like breathing, where one could "hold their heart" like they "hold their breath".

If meditation lowers heartbeat and temperature, I imagine that it's "control" in the strictest sense, but I'd use "influence" or some other term if I was personally describing it.

I didn't think this was special? I've done this in the mirrior? Not fast or anything, but it is "on demand".

Came here to say this as well, I can change mine without moving when looking in a mirror - to me it "feels" like I'm focusing my eyes on something that isn't there.

If you're interested, the article mentions that they're looking for more people with the ability. Theres some contact email address shown near the end.

Not all muscles have a spark plug at the tip delivering its own signal to pulse. The sinoatrial node does this in the heart, and it is a reciprocal system like a v8 engine where one side firing begets the other side firing next. When these signals to fire go out of whack, you get fibril movement, which is when a defibrillator is deployed, it shocks the SA node forcing a 'reboot' of sorts and if all goes well, normal sinus rhythm resumes.

This reminds me of the Bene Gesserit and other schools that sprung up in Frank Herbert's Dune. Once computing technology was forbidden, these schools started research in 'human technologies', learning to control and use their own (or another's) body as a kind of machine. I do wonder if there is any possibility of actually doing things like extending conscious control over more bodily functions, if we were to try at it for a few thousand years (both directly and through selective breeding).
