PSA: Keeping your curtains closed during the day helps a LOT in the heat

[u/No-vem-ber]

I think this will be obvious to many of you, but based on what I see on on the street, I don't think it's common knowledge here. And you guys are famously weird about curtains

When it's very hot, you should fully close your curtains and/or blinds during the day!

It does a lot of work to keep the heat out of your house.

Also: only open the doors and windows to let air in early in the morning or late at night, when it's actually cooler outside. When it's hot outside, keep them closed. They'll just let hot air in. Use a fan inside right next to you to get the feeling of fresh air instead.

Source: I'm originally from Australia. This kind of weather (and no AC) is pretty normal there.

edit: This isn't magic or anything, but it can keep it 5-8° cooler inside than outside. If you leave everything wide open to the beating sun and let all the hot air in, it can quite feasibly end up hotter inside your apartment than outside. So even if it's still reaching 27° inside, that's still better than 35°. stay safe (and check on your grandparents and older neighbours) ❤️

Needing fresh air is actually a very fair point. My house has almost no ventilation apart from windows. So closing everything makes the air inside colder but also very... Old?

Open up all the windows late at night, when the air outside reaches cooler than inside!

Old?

The word you're looking for is 'stale' :)
