These are the reasons
1) Various studies have indicated that sleeping with a weighted blanket can trigger an uptick in the brain’s production of serotonin 2)The other element that might explain our need for blankets is what Hoagland refers to as “pure conditioning.”
Surely that could be a result of conditioning.
This is actually the first time I've ever heard of weighed blankets. As someone with severe anxiety that's helped with a hard squeeze, I'm very interested in getting one, I just wish I could try one first.
> deep pressure touch improves subjective relaxation That could still be conditioning.
I'm not saying it definitely is conditioning, but I don't see enough evidence to rule it out.
For example, these animals could associate the pressure with the warmth and comfort of being the in the womb. So in a way they've been conditioned by being in the womb. Maybe animals grown in a 'test tube' wouldn't give the same results.
