In winter, temperatures are below zero in many regions of Germany.
Consumers often find that their windows are wet.
What helps against that?
Hamburg – Consumers in Germany often have to choose between two things in the winter of 2022: a cozy and warm apartment and a lower energy bill.
What can also often be observed on cold days is a multitude of water droplets on windows.
These can be quite dangerous if ignored.

Damp windows in winter: why does the water form?
Sharp increases in energy prices mean that many consumers in Germany tend to turn their heating down to a lower level.
But if you like it warmer, you will likely be confronted with a phenomenon at windows more often.
Windows often fog up, especially in winter, which is reflected in a large number of drops on the lower part of the window.
This is condensation – but how does it form?
The problem usually comes from the residents, as reported by 24hamburg.de.

The drops on the window form, among other things, when a warm inner wall meets a cold outer wall.
This is particularly noticeable at the window.
But that's not the only reason: especially in the bedroom, there is often high humidity.
When consumers sleep eight hours, around 1.5 liters of water per person are formed through breathing and sweating.
"If the warm air hits a window pane that is cold due to the low outside temperatures, the moisture condenses and settles on the inside of the window in the form of condensation," explains

The problem with condensation on the window is possible mold growth.
Mold prefers humid and warm air.
Mold is often only recognized when it has already spread behind wallpaper or furniture.
The consequences can be devastating.
Asthma, coughing and general breathing difficulties can be the result, especially if you stay in a room infested with mold for a long time.
But what can be done against condensation on windows?
First, consumers should wipe away the water that has formed on the window with a cloth.

It is important to check whether mold has already formed on the silicone.
If the condensation keeps coming back, the cause should be addressed.
Check that the windows are tightly and properly insulated.
You can test this with a simple window trick, for example.
If this is not the case, consider an exchange or contact your landlord.
A dehumidifier can also be bought for little money and work wonders.
The correct ventilation behavior is also immensely important: it is better to ventilate several times a day than to keep the window tilted open all the time.
Unfortunately, not heating is not a solution despite saving energy.
