Breathing Disease - A Cause of Homeless Sun

Mechanically, when we leave home, we let the blinds down, close the windows, or pull the curtains. For safety, of course, but for not allowing the sun to enter. And we often keep our rooms in shadow even when we're at home, because the very bright light is annoying. This practice turns out to be very wrong - the sun - caught rooms are healthier. This was revealed by researchers at the University of Oregon, who conducted a study on tiny dust environments to see if and how daylight influenced the presence of germs, especially those causing respiratory disease. The research, published in the medical magazine Microbioome, has shown that bacterial spread doubles in the dust of the rooms that remain in darkness.

Less sun, more bacteria

Experts used a mixture of dust collected from their homes and deposited it in miniature rooms, which were partly in darkness and part in the sun. After 90 days (the time it needs powder to be placed on the surface after absorption), they have analyzed the species of bacteria present.

A Natural Treatment Against Breathing Diseases

So it turned out that the rooms exposed to sunlight were those with fewer germs, about half of the vital bacteria (those that could grow), compared with the dark rooms. Rooms exposed only to UV (not visible light) had bacteria slightly less vital than those exposed to sunlight.

Bacteria at Home

Some 10,000 different types of bacteria circulate around the house, and many are present in the kitchen.
