Description
In 2019, during the first big heatwave in Paris, I remember how exhausting it already was. In 2026, after four more heatwaves, I saw how much harder it gets for people without air conditioning. Cooling down at home is not obvious, and every window decision feels urgent when you are tired and hot.That is why I built Ventilate: a calm guide for heatwave days, when to open, when to close, and where to put a fan so it actually helps.
Heat is still hitting Europe hard, and I keep meeting people who open windows at the wrong hour or miss the short evening cool-down. Small habits make a real difference.
