Do you also like to close the curtains during the day?
You are certainly not alone in this.
But there's an important reason you should leave them open.
Anyone who is out of the house during the day feels more comfortable when everything is locked and locked.
The curtains or blinds are also often closed - either to ward off curious glances from neighbors, to make work more difficult for burglars * or simply to keep the apartment cool when the outside temperature is 35 degrees.
Leave the curtains open during the day - this is why it makes sense
Scientists working with the study director Ashkaan Fahimipour from the University of Oregan found an important reason as early as 2018, why you should leave the curtains open.
The research group has proven that
light inhibits bacterial growth
- especially sunlight.
For their study, the scientists created environments that should have the typical characteristics of a room.
Among other things, brightness, reflection and humidity were taken into account.
They then tested how the incidence of light affected the growth of bacteria - with an astonishing result.
