In the most ordinary house dust contains more than 9 thousand various microbes. This was recently reported by scientists from U.S.Awho conducted special tests to determine how house dust affects the state of the human body. In the process of the study, experts were able to find out the types and types of such microbes and even the places where they are located.
University of Colorado staff discovered 7,000 chemical bacteriaand 2000 fungi. In the course of this large-scale study, scientists examined 1,200 homes located in different parts of the United States. For samples used a sample taken from the vestibule of the doorway. As a result, scientists found that mostly dust gets into the home from the street, flying through the windows, and also brought on clothes and shoes. To prevent the negative impact of such a number of microorganisms, experts recommend cleaning up indoors, ventilating rooms and going out into the fresh air as often as possible.
By the way, scientists at one time already investigated the composition of house dust and concluded that it can tell a lot about those who live in this house. By identified colonies of fungi, scientists could even determine the location of the house. And by the composition of the bacteria, they easily found out who lives in the house - men or women, and what is the age of the residents. They also determined whether there were animals in the house.
By the way, earlier scientists expressed an even more incredible theory. According to them, dust in the house can affect receptors associated with obese. Researchers at Duke University in the USA claim that substances found in lubricants, flame retardants, and plastics get into house dust and, therefore, act on the PPAR gamma receptor. It is this receptor in the body that regulates fat metabolism. Most alarming is the fact that dust affects young children who swallow it very much, crawling on the floor.
