I can't attest for that point scientifically or even personally.
The argument in #9 as I understand it is, over the course of your lifetime, the cumulative minuscule effect of how you sleep relative to the Earths magnetic field can have a negative effect on your health, increasing the risk of stroke or brain related conditions.
To prove or disprove would require long term study (in the order of a human lifetime) with equipment capable of detecting very small changes while eliminating all other effects.
I wouldn't downvote you (even if I could) for adding to the discussion, but this certainly isn't the sort of content I come to HN to explore. Outlandish claims without anything to back them up.
I didn’t downvote you but claiming meditation and yoga substitutes for sleep pattern matches to quack/idiot. Your link has the word guru in it which points the same way. Personally I find it credible because I’ve read studies before suggesting meditation can substitute for sleep 1 for 1 up to some threshold but I’m too lazy to search for them. If you make claims that are as credible as a homeopath or anti-vaxxer cite something that at least looks credible.
Fair enough. Was in a hurry. Was obviously a topic that needs more detail. Have also seen those studies (via HN) - in fact they were what originally got me curious about meditation about 5 years ago.
Edit: downvotes why?
