NOW that cooler weather is here, you may notice condensation starting to appear on your windows.
This occurs when warm air in your home meets the cold glass, and the water droplets that form can lead to unpleasant mould.
If your home becomes mould-ridden, it can cause a number of health issues, including asthma and bronchitis.
Condensation is more common in homes with poor ventilation and insulation, but thankfully there is an easy trick for banishing it.
One Reddit user shared the German concept of Stosslüften, which is when you tactically open a number of windows in your home at once.
While you may think this sounds chilly, if done correctly you can successfully remove condensation in a short period of time.
The person wrote: “In Germany, we have a technique called ‘Stosslüften’, or ‘shock ventilation’.
“What that basically means is that instead of having maybe one window open all day (which is a huge waste of energy), open several windows all over the house for three minutes, creating a strong draft to exchange most of the warm humid air inside the house with cold air from outside.
“A cool feature about cold air is that it can ‘hold’ less water vapour. If this relatively dry cold air enters your house, it warms up. Being warmer, it is suddenly capable of taking up some of the extra humidity from inside your house.
“This might sound a little weird at first but is advocated in schools and so on. I use that technique and it works. Do this several times a day and you should really see a change. Maybe get a device to show you the relative humidity inside your house.”
University researcher Raymond Galvin at Cambridge University backed this theory up.
Speaking to Politico, he said: “The correct way to ventilate a home is to employ the Stosslüften, or shock ventilation method.
“You open your windows completely for three minutes if it’s windy, five to 10 minutes if it’s not”.
