Is it OK to sleep in a room with the windows open when it's - 1?

Just that really... my kids window just wouldn't shut tonight. Its wide open, they have fleecy onesies on and duvet plus blanket. They're 9 and 12.

I always have the window open in the bedroom regardless of the temperature.
They sound like they are well wrapped up.
They will be fine op

Yes. I never close my bedroom window. I need the fresh air circulating!

Is the window secure when open? As a result of far too many True Crime podcasts I would be wary of leaving my kids in a room with an unsecured window...

I always sleep with the window open, they'll be fine, they'll wake up if they're cold, they're not tiny babies. It's much healthier to have an open window.

I used to live in the Swiss Alps, and would have my bedroom window open when it was minus 17.

I always sleep with all the windows open! Bed is warm though. Put on extra cover on if you're worried.

Well, they’ll live but it’s not ideal. Does it have to be ‘wide’ open?

I have it slightly open when there is snow even.

I always have my bedroom windows open.

I like the cold fresh air plus the warmth of being under the duvet.

I find it stuffy and awful without the fresh air.

So yes, they will be fine - in fact it's probably better for them.

I always had e my windows open, I did shut them when it got to minus 17, which was once about a decade ago.

I always have the window slightly open. -1 is nothing! If anything they'll be too hot in all those clothes, I'm currently in bed without clothes and with just a duvet.

It's -1 not -50! 😊. All our bedroom windows are open a smidge all year round.

The OP says "wide open", not open a crack. There is a big difference! I don't think it's ok at all and would have moved them into a different room. Given that it's now morning though I suspect it's done now.

@boomwhacker I take it you've never been camping at Easter? 😂 Now that really can be cold!
