Cool Touch Bedding - How to keep cool in this awful heatwave?

[Nachtvlinder]

With this heatwave we're having, I'm not coping very well at all being post-menopausal, plus my bedroom is the hottest room in the house. I can't have the fan as I can't stand the noise, and I have the lightest duvet tog (4.5) but usually my legs, back and arms stick out.

I've heard of these "cool" bedding, and I'm wondering if these are worth the investment? Do they stay cool on your skin constantly or do they eventually absorb your body heat, so then you'll have to move to the untouched parts of the bedding to cool yourself again? I have no idea on what to choose, and my budget can be stretched to a £100 or so if they are definitely worth buying. I'm always hot on my head/neck, back and armpits and leg areas.

Having the window open last night didn't make a jot of difference as there was no breeze. Thank goodness for the downpour we've had earlier (first rainfall for 4 weeks here, but it won't last as the temps will rise again this week).

Last year's heatwave was awful; resorted to having in feet soaked in water WFH (feet got very wrinkled - not a good look!) Fan had strips of wet cotton in front of it that didn't work. Roll on winter!!

I have just a sheet artfully draped over me and then flung off at about 3am

Surely you don't need a duvet? I know some duvets are meant to have cooling functions etc but I can't see how 4.5 tog won't make you hotter.

I'm from a hot country (for context, I don't ever find UK heatwaves hot in the least, and I'm in the "hottest" part of the UK) and we don't use duvets at all, only extremely thin cotton or silk blankets. Those don't have to be £100!

We use duvet covers without the duvets inside. Also those medical ice packs are great wrapped in a pillowcase.
We've got all the windows open (with bug screens) and children have powerful fans. We've got an air conditioned annexe in case any of us feel too hot but try not to use it too much as it's expensive to run.

Oh and by cotton blanket I don't mean the thick throw kind I see on amazon UK. I mean one that's the thickness of a flimsy beach t-shirt or cheap bedsheets

When it's hot like this we ditch the duvet and just use a flat cotton sheet. Natural fibres like cotton or linen are key, any sort of polycotton feels hot I find.

Dh sleeps on top of the duvet for about 75% of the year anyway but when it’s warm like this I just get a bottom sheet out and use that, I can’t sleep with nothing! And actually I still find that I’ve crawled underneath the duvet come morning!
I don’t like the fan noise but it does drown out some of dhs snoring so I tolerate it.
It’s not that hot here, my bedroom is measuring 27 so certainly warm but last year it was 32 for weeks at night in my room. This house is bloody well insulated.

I was asking about these so-called "cool bedding" that are on the market from JL, Tempur etc. I will of course, revert to using a cotton sheet rather than the summer tog duvet.

I have the comfortably cool stuff from M&S and really like it

I have cool bedding and it is excellent in this weather

I’ve never tried the ‘cool’ duvets you’ve mentioned but linen bedding is really good for not holding the heat.
