Exactly, the flushing effect. Which you can also feel when you do some forms of meditation :)

I'm curious - do you have a physical sensation when this happens to you? Is there any evidence to support this claim? I ask because I often feel similar to brushing my teeth when I meditate, it's hard to explain though.

I can relate, but I interpret it as mental cleaning. Letting go of garbage thoughts etc, not literal toxins through the blood, but I assume it also helps this process, by relieving of stress. A body under stress works intentionally different, than a relaxed body. (Stress means some kind of threat, not the time to do cleaning)

You have no physical sensors that would allow you to "feel" events up there.

Not literally, though 'feeling' does a lot of work in that sentence and rightly so. You don't exactly have a physical sensor to 'feel' sad either, which also happens up there mostly, but still people usually accept that we can 'feel' the experience of sadness. Becoming aware of mental states influencing perception is how you register events up there (using meditation), which is what 'feeling' means in this context.

You can also feel things which don't exist, or not feel thing which exist, that's not really a basis for scientific discussions

Your eyes can't feel infrared yet they exist, and your eyes can be tricked into feeling movement when there is none (optical illusions)

I can find you people who feel the influence of Saturn on their mood...

I'm always wary of people using scientific lingo to "prove" their "feelings"; "flushing", "waves", "energy", "toxins", it's way too easy to fall into new age mumbo jumbo

Obviously the article leave a lot of the science out, but this sounds like it’d be an easy thing to test for (which they’ve now done). Why wouldn’t this have been done years ago - I’m not trying g to say they should have done it earlier, as I genuinely don’t know. Is the tech to check this new? How much other science has been based off of this theory in the meantime?

Did they test it succesfully? Did they make some blunder? Did they misrepresented the importance of their results? Will it replicate? Does it apply to humans? I wouldn't be bothered with putting much faith on any of the papers coming out, unless I was a researcher in that space. The dust is far from settled.

Oh me neither, I’m less interested in the results and more that (to someone who has no idea behind the science - me), I’m surprised to hear it’s just now only being tested when I’ve heard this was the main theory of sleep for years.

This seems like a pretty strong claim. What do you mean by physical sensors?

How does the body "up there" manage itself without being able to sense and interact with the physical (and chemical) world?

And? Does it succesfully refute it? Or is the new study just another study with bad methodology that wont be replicating? Or maybe the first one is? Individual studies aren't worth considering, especially after they just came out. Call me when they have settled about it, 10+ years from now.

The way they refute it is interesting. > Those authors observed that fluorescent dyes injected into the cerebrospinal fluid (CSF) via the cisterna magna penetrated further into the cortex during sleep and anesthesia. They interpreted this as showing that molecular movement into the cortex must be faster during these states. However, the concentration of dye in any brain region will always be the difference between it…

Sensors? Heh :) Well, however I am able to do this, I do it. And I feel it. And you don't know. So, your model must be wrong.

It seems you don't trust your capacity for feeling. You need to develop that more, then maybe you will understand.

What you say is common among people who have not learned yet
