Help me survive this week’s heatwave

Not really an AIBU, posting for traffic. In brief: I usually work (in home office) and sleep on the third floor of my house (kids are on second floor), but the third floor becomes unbearable above about 27 degrees, which of course is becoming an issue with increasingly hot summers. We’re also unfortunately near a busy road which makes opening the window unpleasant (didn’t used to be like this but has become busier over time).

I’m looking into permanent air con, but I have a work deadline this week and need to be able to sleep and work. May be able to work in the local public library which has air con, but I need to be able to sleep!! Hit me with your best recs for portable air con units and/or light roll up mattresses that I can use to sleep temporarily on the ground floor and/or anything else? Am I right to think portable air con units will all have a hose that needs to go out an open window? In which case, unfortunately, it’s not a great solution for my house due to traffic noise. Very open and grateful for any proposed short-term solutions…

Tepid shower before bed, wet your scalp. Don't towel dry just wrap a sheet around you lie down and let the water evaporate.

Sleep on the sofa on the ground floor.

Yes, I noticed the Meaco fans someone mentioned have gone up in price too. Naked Profiteering at its finest.

Cooling mats made for dogs! £12 in pets at home. My daughter really wanted one and she has been sleeping with it over her. It also has a nice bit of weight so is relaxing too. I think I might borrow it and take it to work tomorrow (school, no air con)

It was these people. It looking at their website now they have much less on offer than they did when I looked. But might be worth calling them.

The delivery man didn’t bring it up the stairs - had to prevail on male friends to help…no way I could have done it myself!

Thanks so much - I’d had no idea they were something you could hire. It looks like that service is in London unfortunately, but I’ll have a search to see if I can find one closer to me.

Oooh now this is interesting! Who did you rent it from @easterb?

Thanks to everyone for the recs!

Completely sold out now, sorry but the delonghi pinguino air conditioner has been transformative for our room. Yes it does need to be vented out a window but once set up its ability to cool the room provides a cool haven.

I’m no longer apprehensive when hot weather is forecast.

When we got it, a good few years ago, the weather broke on the very day it was delivered. Kicked myself at the time but now it’s so good to know it’s available when needed

Itsnotallaboutyoulikeyouthink · 23/06/2026 06:59

I live in a three storey house and you won’t be able to sleep on the top floor. My son hasn’t been able to for about a month now as it gets so hot. Just move your mattress onto ground floor and sleep there.

alternatively hang a sheet on the outside of your windows to stop the sun directly hitting the window. That will take and edge off and help it generally be cooler but you still won’t be able to sleep there.

Hire aircon unit for the wk. Pricey but so worth it

If you freeze your hot water bottle repeatedly, don't use it for hot water in future as it weakens the rubber and can lead to splitting. You can buy cold packs online which are specifically designed for repeated freezing. Just wrap them in pillowcases and take to bed with you or wherever you need them.

Bamboo satin pillowcases and sheets.

There are some really good freestanding fans on Amazon which have a cooling effect despite not being air conditioning units. They're best on a low setting blowing air straight at you, but you might find that they help cool the room down very slightly.

Came here to say this. Best idea, if you want to do the hot/cold water bottle thing is to have two separate ones (different colours so you remember which is which - maybe red and blue).

You do not want to risk damaging the bottle rubber or the seal - could be disastrous when filling with boiling water in the winter.

Wash your hair and don’t dry it, go to bed with it wet

Bluewombler · 23/06/2026 00:37

Library with air-con???? Good luck with that

GaIadriel · 23/06/2026 00:20

I'm fine with a floorstanding fan and earplugs to block out the noise. And I'm defo somebody that runs on the hot side and doesn't really feel the cold.

I bought a gel cooling mat for my dog, but looking at the reviews people use the large pet ones to sleep in in bed

This is exactly what I was going to post. My dogs weren't interested in them so I put them on the sofa and in the bed. I don't know how much they are now, but I paid £5 for each of them a few years back from B&M.

These are the bra inserts https://issviva.co.uk/products/issviva-cooling-bra-inserts
it says £19.99 but seems to give a £5 discount at checkout, or a slightly bigger discount if you buy two pairs.

They are amazing and should be better known!

I have a Dyson fan which is pretty good.

You can get a flat thing you freeze and put in your pillowcase and your pillow will be cooler for much longer.

I have some cool gel inserts I put in my bra. I freeze them and they are amazing. Because they are over your chest/heart they really make a difference.

On holiday in Italy with no air con we froze large pans of water and put them in the bedroom an hour or so before going to bed. This was quite effective and the ice cracking sounds might help cool you as you pretend you are in icy seas.

I drink a hell of a lot of water - if you are like me and risk drinking too much, put a pinch of salt and sugar in to replace electrolytes and ensure you stay hydrated.

I've bought this blanket off amazon. It came today. I don't know how it works, but it's absolute saving me right now. Just me, my period pants and this blanket are having a fabulous time. It's 23 outside right now which is hotter than the 28 in my bedroom so I've got the window open for as long as I can.

I absolutely cannot sleep with them (windows) open through the night. Hard no. We are very rural and have bats etc.

We are in a Victorian loft conversion and it’s hot. Through trial and error I have pretty much decided that it’s actually better to leave the windows open (velux one side, normal the other) as other wise the heat gets trapped and it ends up like an oven. I understand the theory about not letting the hot air in but I think there a limit as to how effective that is. I do have thermal blinds on the velux windows but keep them open.

I keep both bedroom doors open to make the most of any breeze.

I sleep in the lounge on the sofa in this heat.

Tolodex · 22/06/2026 18:45

OP I also sleep on the top floor of the house and work here and it’s baking. When it gets above 30 my brain actually doesn’t work and fans don’t help. I finally gave in and ordered an ac unit last week. I only use it for 2 to 3 hours in the afternoon, but gosh it makes such a difference.

I was stressing so much I decided to rent a heavy duty air conditioner unit - £55 per week plus Vat. I’m going to have it for two weeks. They delivered it the same day I ordered it and also collect at the end of the rental. Delivery was £30. It’s brilliant and has made me feel much better about the coming week! It is heavy (35kg) though and a cumbersome shape so it required two strong men to get it up the stairs.

Expensive I know but I feel so much better and will hopefully be able to sleep this week.

Did the delivery men bring it up the stairs for you? I don’t have a strong man in the house unfortunately…

Same problem but sleep on a Jay-be folding bed downstairs (Argos). Failing that I recommend a Vango inflatable mattress, one of the 15cm plus thickness ones.

TheSandgroper · 22/06/2026 07:01

Australian here in Perth.

We have a reverse cycle air conditioner and mostly run it on Dry mode. I save the Cool mode for the worst part of the day. Movement of dry air by fan is much more comfortable than still humidity. So, my biggest tip is to close up your house and get out your dehumidifiers. You really will be so much more comfortable.

I find a larger airspace cooler than a smaller, enclosed room so often sleep in my lounge room near the doorway as that’ll be where the air is moving.

I may also have a fan on. I don’t like the fan on me directly so point it at the wall and have the air slide over me that way.
