Your curtains can only be the culprit of that flu
It is easy to keep the curtains closed in the bedroom, for example, but according to research that is not a good idea at all.
Are your curtains usually closed or open?
It is winter so the curtains are closed more often than in the summer. It creates a cozy feeling, but it also keeps the heat inside better. People with a house on the street or where you can easily look inside also have the curtains closed a bit more often. However, this appears not to be so useful.
This is why you can keep your curtains open better during the day.
When you get up in the morning in the winter, it is often still dark outside and when you return to the bedroom after a long day, it is already dark. Many people simply leave the curtains closed, but if we can believe researchers from the University of Oregon, it's better to open your curtains in the morning.
According to the findings of the researchers at the American University, if you keep the curtains closed all day, the chance of a flu is increased. The researchers assume that natural light kills certain bacteria that are in space. However, the conditions in a dark room would be so favorable for these bacteria that they can survive and adversely affect us. In other words: we can catch a flu because of it.
To arrive at these findings, the researchers set up eleven rooms that were all identical to each other. The only difference was the amount of light that entered the room. After ninety days, the researchers took a closer look at the spaces and the darkest room contained twice as many bacteria as the room where a lot of light entered.
