Ask Lemmy

During winter, having them open for any significant time would risk plumbing freezing. During summer, it's usually a matter of opening them at night so the coolness lasts through the day.

In the winter I have no control over the heat. My radiator has a direct line to the pits of hell. So the windows are open all winter long. They are open in the spring and fall as long as the temp inside will be comfortable. Closed in the summer because AC.

I rarely ever open windows unless someone asks me to. I get a lot of complaints during the summer of how hot it is indoors, but I adore the heat.

I open the windows during winter even when it's like -30c, at some point the air gets stale and circulation is needed. The stuffy air also makes my headspace feel weird, like something is irritating me but I can't tell what it is.

Then at some point I open the windows, I also runna huge flan to circulate air around.

My building is on an old chiller system, so my AC is off ~5 months out of the year. My windows are open the entire time, and I usually have fans set up too to try and keep things cool.

When my AC is on, absolutely never. It is hot here like 7 months out of the year. 

A lot less than I want and need to. My social anxiety is ridiculous with small stuff like this, just opening the windows easily gives me anxiety because I hear people outside. It sucks but I often manage to do it for a while before I have visitors, just so the air fresher.

Whenever it's vomfy

German here: yes. 24/7

Paris here, we sleep usually windows (slightly) open, yes even now in winter

Spain, in winter at least 15 minutes in the morning after waking up and 15 minutes in the evening. In Summer I try not to open the windows during the day only at night because I will be naked alive otherwise

When we taste the air is a bit a stale, we open the all the windows and sliding doors to exchange the air during all seasons.

Daily, all year roun,for a short time.

Let me introduce you to Stoßlüften.

I got a Technoline WL1030 meter for my room and whenever it reaches 1500 ppm CO2 I open the window until its back down below about 600-700, then I close it to not waste more heat than necessary

Edit: To give some more context, my room is 14 m^2 and about 2.50m high so roughly 35 m^3 of air minus some occupied by furniture call it 30 m^3 maybe. It is a modern house with good insulation and energy retention rating (built to the "Minergie" standard we have here in Switzerland), but without forced air, so not much air is exchanged when the windows are closed. With this I end up roughly having to exchange the air every three hours or so.

Almost never. I lived in a bad neighborhood for too long, so I doubt that habit will change.

Still too much! I haven't migrated everything to Linux yet (poor me).

In the winter, Stoßlüften, especially to get moisture out in winter, to reduce and clear out condensed water on windows and prevent mold. I guess bathroom after a shower more than other rooms either way. In the summer, full night, none during the day.

Sometimes not for a few days, sometimes multiple times a day, sometimes open all day. Depends on the season and a few other things.

I find that I need to open them 2-3 times a day.

I open them when humidity goes above 60% in my room, and keep it open until it reaches under 50.

This usually means opening them 2-3 times daily.

Otherwise I get the same suffocating feeling.

This definitely varies by region.

Dane here. I open all windows for five minutes two times a day, also in the winter.

I use linux

Rarely, I just have my AC on to make it hot or cold and the solar panels make it almost free.

Window open means bugs get in, and they tend to like lights like my computer screen and I'm sick of cleaning bug goo off the screen.

Southern US, windows are only open in winter, basically whenever it's comfortable outside. Never in the summer. The A/C runs basically 24hrs a day during the hottest 2 months of the year.

Windows on the car are basically left cracked for the opposite time. Rain deflector are installed to allow for this without rain getting in.

Where I live, there's usually 3-4 months out of the year that it's better to open the windows to let the air in than to use central air. Cheaper as well. In the winter we usually get a day or two where it's warm enough to open up to let air circulate. But swamp ass summer and deep winter here suck eggs to be opening the windows.

Honestly. I used to always keep my window open* over the night. This winter was the first I have regularly not opened my window and just opened it for a bit during the day (yes stoßlüften), which I of course did before as well, since I'm German 😅

* when I say "open" I mean my window would usually be tilted open ("gekippt") not fully opened wide

Spring: Never, my partner is allergic to tree pollen released during the spring, nor does the indoor temperature warrant opening the windows

Summer: Sometimes in late summer - I am allergic to grass pollen highly prevalent in early summer. Once they clear, I open the windows when it's warmer inside than outside, to cool down my apartment slightly

Autumn: Rarely. The temperature usually does not warrant opening the windows

Winter: Never. It's far too cold to let heat intentionally escape

How I avoid suffocation: my apartment is well-ventilated, this is not an issue whatsoever

I never open Windows regardless of season.

I like the fresh scent of Mint in my house instead.

I basically never open my windows. This winter, I don’t think I opened them at all except maybe during a big cleaning day.

In Japan, ventilation is required by law, and most modern houses are equipped with a 24-hour ventilation system. Because of that, we don’t really need to open the windows to get fresh air — the system continuously circulates air for us.

At the same time, it doesn’t make the house noticeably colder in winter or hotter in summer. The air also goes through filters, which is especially nice during pollen season.

So I don’t really feel suffocated even with the windows closed, since the air is still being exchanged constantly.

Only close them if it's raining

I hate Windows

Northern Spain here, they remain closed all winter except the few times I open them to ventilate. Next month I'll probably start opening them during the day and at some point in May or June they'll remain open until the end of September or so.

Never of course. Don’t know exactly what Winter and Summer mean, some desktop environments maybe? And what is fresh air?

I try to keep windows open as much as possible. I also struggle with breathing when they are closed. During winter tho it’s a struggle. My mom gets furious when I turn the radiator on and set it to anything above level 2 and she never ups hers above level 1. So I’m suffocating and freezing. Sometimes I gotta turn the fan on for a half hour just to get some relief.

Honestly I’ve given up on trying to save on heating during the winter. Even with everything closed my house is drafty as fuck. I’ve got one whole room on the ground floor that was an addition built later and no one bothered to run ventilation into it, so it needs a space heater. Yeah it gets stuffy but I’d rather be warm.

Spring and summer are a different story. I love spring and summer air and I open everything.

Your parents are right in terms of energy waste, im sorry to say.

I'm quite similar though and air about five times a day but with a timer so that the air gets circulated completely without cooling out the house itself.

The breathing struggle is most likely a mix of dust sensitivity and psychology. For me an air cleaner made a huge difference in my comfort level.

I'd you want to go the scientific approach get a CO2 monitor (the most important element for brain performance when talking about home air) and a PM2.5 sensor for dust levels.
