We decided a few months ago to take down any blinds that did not interfere with our privacy. We did that because sunshine is so invigorating streaming into the house, and when it did, even on just a partly sunny day, we always were in a happier mood. So when we read the below article we knew that there is another great reason to have taken them down.
According to an article published in Science Daily, letting the sun shine into your home through the windows can actually kill bacteria that live in dust and this can help decrease the risk of respiratory issues. The article references a study published in the journal Microbiome, describing how researchers at the University of Oregon led by Dr. Ashkaan Fahimipour, PhD, created climate-controlled rooms and exposed the bacteria found in indoor dust to three different situations: one in a dark room, one in a room with visible light, and a third in a room with ultraviolet (UV) light. After 90 days, results were collected from each environment and studied, and there was a correlation between light exposure and the number of bacteria in the dust, noted the article. Bacteria that were kept in the dark were also more closely related to respiratory diseases than those that stayed alive even with exposure to sunlight.
"Our study supports a century-old folk wisdom, that daylight has the potential to kill microbes on dust particles, but we need more research to understand the underlying causes of shifts in the dust microbiome following light exposure,” said Fahimipour, an expert in experimental and computational biology at the university.
We are lucky that our home is situated in such a way that we were able to do this with most of our windows. I hope that you can consider doing this with many windows in your home as well.
