De onde vem e do que é formada a poeira que acumula na sua casa?

What makes up most of the dust in your home? Is it true that most of it is dead skin cells? Okay, fact: The average home collects about 40 pounds of dust per year. One of the most popular myths about house dust is that it’s mostly made up of your skin cells. But in reality, dust has a much more complex structure. You bring dust into your home from outside. And even if you never leave the house, you’ll open the windows to get some fresh air. That’s when even more dust gets in. If there are trees right outside your window, you’ll get a little more dust from bird feathers and dust mites. In addition, dust comes from carpet lint, clothing fibers, your pets, and even your food. Bits of fiber and food crumbs from your lunch contribute to the composition of dust. The same goes for your carpet, rugs, curtains, towels, and upholstered furniture. Your clothes shed fibers that turn into dust. If you use fabric softener, you're only making things worse. It gives fabrics a nice smell and extra softness, but that coating flakes off and creates more dust. And yes, you're a source of dust, too. But what about the percentage? #brightside TIMESTAMPS: Why Fabric Softener Makes Things Worse 1:34 You're a Source of Dust 2:18 Dust Mites 3:22 Dust Can Cause Serious Health Problems 4:36 What Would Happen If There Was No Dust? 5:35 Subscribe to Bright Side: https://goo.gl/ZHFt2x ---------------------------------------------------------------------------------------- Our Social Networks: Instagram   / ideias.incriveis.oficial   Facebook:   / incrivelclub   IDEIAS INCRÍVEIS http://bit.ly/2WNlEcw ---------------------------------------------------------------------------------------- For more videos and articles, visit: http://incrivel.club Music by Epidemic Sound https://www.epidemicsound.com/ Stock materials (photos, videos and others) https://www.depositphotos.com https://www.shutterstock.com https://www.eastnews.ru
