Did I have hypo when asleep last night ?

Cold sweats are a common feature of both day and night hypos, but sometimes seem to happen more often at night purely because with a day hypo, you'll often catch it before it get's that far, whereas if you're sleeping, then there's a chance you'll miss it simply because you're sleeping. I've often woken drenched from head to foot and freezing cold. There's a wristband called Hypoband at www.hypoband.co.uk which measures temp and humidity on the wrist and alarms if it gets too cold and wet. I got one a few months ago but typically enough I've not had a cold sweat since then so can't say if it works! Maybe it's got some sort if weird placebo effect which stops them...

It'll obviously not stop a hypo because it only alarms once the cold sweat has started but I decided to get one anyway in the basis that it'll hopefully wake me early on so I can intervene before the hypo gets too deep.

I'm looking at some of the Libre hacks which make it alarm, some ingenious stuff out there.
