A new study reveals there are around 9,000 species of microbes in our houses. This doesn’t mean that we need to reach out for cleaning products right away because scientists say we shouldn’t be too worried about them.
A team of experts from the University of Colorado looked at dust samples taken from 1,200 homes from various parts of the United States. They asked the volunteers to provide dust located both on the interior door trim and the exterior one.
The participants were also surveyed related to the number of rooms their house had, how often their windows were left open and other aspects that could help them check certain factors after analyzing the samples.
The findings of the study published in the Proceedings of the Royal Society B showed that the dust predicts a lot about the people who live in that particular home. It provides information related to the predominance of male or female residents in the house, the type of pets they own and even the climate and geographical locations.
Most of the dust contained dead human cells, particles of insects, pollen, soil and various types of bacteria and fungi. According to the scientists involved in the study, most fungi came from outside the home, not from the inside and they did not represent a threat to human health.
Basically, people don’t need to worry about the particles of dust in their homes, even if the place we live in should be cleaned on a regular basis.
“People do not need to worry about microbes in their home. They are all around us, they are on our skin, they’re all around our home – and most of these are completely harmless. It is just a fact of life that we are surrounded by these microbes,” said Dr. Noah Fierer, an associate professor of ecology and evolutionary biology at the University of Colorado, who is also the lead author of the study.
Even if the study was conducted in the United States, the researchers believe that the same findings could be revealed if dust samples were collected from other parts of the world.
