I’ve learned that not wearing pyjamas just soaks the bed with sweat, so might as well wear them and just change them out in the middle of the night as and when needed.
I’ve learned that sleeping with the window open only does nothing but ensure that I hear the birds at 5 in the morning
I’ve learned that a decent blindfold works better than any curtain
If you don’t already, wear breathable pyjamas, and cotton bedsheet/duvet cover. And ideally, a non-synthetic duvet.
This will at least reduce the liquid sweat, by allowing it to evaporate better.Keeping track on when it’s hot/not/rainy can help get the house temperature under control.
When it gets cooler at night, you can open the windows to cool the fabric of the house down.
Then close everything up first thing in the morning, including south facing curtains.
The cooler you can get the house overnight, the more heat it can absorb the next day.
So here, I left the window open on one room, (red) and closed on another (dark blue and teal).
When the outside temperature (purple) dropped to 15 overnight, it dragged the orange room down significantly.
(Then I forgot to close the window in the morning, so it kinda got negated 😬)Other than that, a dehumidifier may help if feeling less muggy, though it will raise the temperature of the room overall slightly, since it’s going to use energy to run.
Externally run aircon is, unfortunately, the only real step beyond that. And it’s a bit of a chunk of change (£500 for a basic DIY one, £1500+ for one room professionally).While a cheap evaporative cooler doesn’t help with the humidity you can boost the cooling effect dramatically by adding cooler blocks to the water and even more by placing more cooler blocks in a plastic under-bed container in front of the fans.
If the sound is disrupting then closing the bedroom door and running it in the evening before bedtime works fine.Cooling yourself with evaporative anything is counterproductive: the extra humidity reduces your body’s ability to cool off with sweat.
Essentially, it transforms dry heat into wet heat, which is much worse.
And OP’s sweat problem is gonna get much worse.
If you wanna get cool, there ain’t too many ways to avoid getting an AC.
There is a dehumidifier setting on most ACs that does the job well at about 10% of the cost. We use this in Spain with the temperatures, when they’re reasonable but high with humidity.
Most portable units you will need a tube/bucket set up for the runoff.
We use the water accumulated to water our plants…Win-Win.
I have a dehumidifier at home that does only this and the heat is exhausted indoors instead of outside…
It’s not that useful as the room heats up more than the humidity being removed is worth, but I’m considering getting a cheap portable ac unit but I’m worrying about how to install it on my window… And the efficiency being much worse than a properly-installed heat pump where I can close the window when I use it…
oh no, the excess heat should be vented outside, usually with a tube connected to something rigged up to close the window.
We’ve used cardboard cut to fill the gap, with a circle cut out to fit the tube, and the whole thing sealed with duct tape…ugly but got the job done so you can sleep (and make a better solution)
Yeah, I’m aware the heat needs to go outside… But I’m not a fan of isolating things with cardboard. And the dehumidifier is just that and doesn’t have an exhaust pipe.
Much depends on the house. Traditional UK family housing with 2 plus stories and fron and back windows are far easier then modern subdivided multi flat buildings.
The older building allowed concentrating on air flow by opening highest widows and drawing curtains that face the mid day sun. While opening lower windows on the low sun side. During the night crated a natural flow of air.
Modern housing means the internal divisions and often lack of non concreted areas. Often prevent cooler air being able to flow. Or existing if the concrete hass 0 shading from the days sun,
Single level can still do it. But much less effective as the temp difference is less. But when the internal layout limits airflow from the high sun to low non sun side. Way harder.
Downstairs fans running overnight while sleeping with upstairs top windows open. Can be a huge difference.
Or just remembering the direction goal of fans. iE removing higher air while pulling in from lower.
It’s common for folks to place the fan between them and the window blowing at the bed. This is the worst thing as you are preventing hot air from leaving. Assuming you are not on the lowest floor.
