Blanket for Chilling

[Yupo]

I read with interest this story on SOTT about weighted blankets:
https://www.sott.net/article/318676-Weighted-blankets-found-to-ease-anxiety-stress-and-insomnia
There is a comment attached there to the effect of 'too bad we can't use these near the equator as is too hot for blankets'. So it got me thinking about weight and thermal factors. FYI, I am trying to do without A/C this summer, so heat relief is much on my mind lately.
I decided to try to make a chilling blanket. I bought some soft but sturdy tulle-like fabric (a non-scratchy version of the medium gauge mesh) that was tear-resistant and some steel and copper BBs. I planned to try to make a few larger than bean bag type swatches in various stitch, layer and channel conformations for testing as cooling covers, given that the metal should contact skin a bit while being thermally conductive. Also want to test to see if the metal will hold up to an occasional dip for washing, or for exposure to perspiration. If the skin is warmer than the room, some chilling should happen.
Unfortunately, all 3 of my sewing machines broke, one by one, before I could sew a single seam. Weird! Not giving up, though.
I'm seeking some thoughts here on risks/benefits of metal on skin. The steel BBs are not stainless. The copper ones are all copper, so far as I can tell.

I remember going on school trips as a child and the thin cotton sheets would always be tucked under the mattress, so when i would slip under, the tension would still be exerting some pressure, and i remember sleeping very well. I guess it could be where the phrase parents say they'll 'tuck you in' comes from. I know the article kind of references it with swaddling a baby and so on.

(tuck someone in/up) Make someone, especially a child, comfortable in bed by pulling the edges of the bedclothes firmly under the mattress: Emily was only too willing to be tucked up in bed by nine

So maybe there's a low-tech option where you can find a way of adding tension to the sheets rather than actual weight. Maybe silk sheets would be particularly cooling? Expensive though. Plus the added anti-EMF effect may be interesting. I know it's not exactly what you were asking so fwiw Yupo :)

I think it may be okay as long as the metal is not in direct contact with your skin and is covered by the blanket. I'm just wondering about the metal conducting emf waves onto your body while sleeping. Do you use wi-fi in your house or sleep near an outlet?

If AC is a no go for you this season you may want to check this out:

Maybe using one of the emf shielding mesh fabrics would be a better choice in this case. I think the metal would have to touch the skin, just a little, for the heat to be conducted. Any other type fabric would insulate.
