If you've been managing to sleep through the night over the past few days during this heatwave, please, tell us your secrets.
However, if not, then you'll probably be interested in the soft, cotton-blend nightdress that we've spied on the Marks & Spencer website.
The brand new Cotton Modal Lace Insert Nightdress epitomises everything we love so much about M&S: it's classic, simple, comfortable and affordable, without any airs and graces.
It's the perfect go-between for when it's not hot enough (or you aren't comfortable enough) to sleep sans clothing but also can't bear the idea of your usual, warmer nightwear.
If you aren't sold already, here's exactly why we love it so much - and why you're unlikely to catch us sleeping in anything else, all summer long.
Why we rate it
The cotton-blend fabric is combined with M&S' patented Cool Comfortable technology, which actively draws moisture away from your body as you sleep to keep your body temperature regulated and save you waking up feeling sweaty after a hot night.
Plus, the lace trim and V-neckline give the piece a soft, feminine feel and mean we'd feel comfortable pootling about the house wearing it in the morning as we make our breakfast (and let's be honest, work from home life means we'd probably leave it on until lunch).
It's available in sizes 6 to 26 and it's both washing machine and dryer safe, so cuts out any cleaning stress.
