House dust can make us fat. Scientists say we should keep our house clean. The scientists did research on mice. They found that house dust made the mice fatter. The dust changed the hormones in the mice and made them fatter. Even small amounts of dust made the mice fatter. We breathe in and swallow a lot of dust.
Dust has chemicals called EDCs. They are in sofas, carpets, cosmetics, food packaging and cleaners. EDCs are in most houses. They can be bad for our health. Children are at most risk. EDCs can lead to learning problems. They can also increase the risk of cancer. The researchers say we need to look at the safety of EDCs.
