Household Dust Can Cause Obesity, Research Points Out

There are a whole lot of factors that contribute to one’s growing weight. From one’s diet, physical activity, genes to sugar, insulin, leptin resistance, etc. Now science has taken the veil off another factor which can contribute to the problem – household dust.

So how does dust cause weight gain? Research says that dust contains chemicals that can trigger the development of fat cells which, in turn, may lead to obesit. This is in connection which the effects that endocrine-disrupting chemicals which can be found in cleaning products have.

Not only are these chemicals which disturb the endocrine system a contributing factor for obesity, but they can also cause cancer, liver disease as well as fertility problems. Chemicals found in cleaning supplies can also irritate the throat and the eyes.

A new study talks about this further saying that household dust can cause obesity because it contains endocrine-disrupting particles.

What Does This New Study Reveal?

The research which was led by Christopher Kassotis, Ph.D. proves that household dust can increase the growth of fat cells because it comprises of endocrine-disrupting chemicals. The findings of this research were presented at ENDO 2019 which was held in New Orleans, LA.

For the purpose of the study, Kassotis and his team looked at existing research that shows the link between these chemicals and impaired fat regulation in animals. They collected 194 different household dust samples from central North Carolina to study the effect that this dust had on the metabolic health of the inhabitants of those houses.

The research team took out the chemical particles from the dust samples and analyzed them. It was found that low amounts of these chemicals did encourage the development of precursor fat cells and hence, fat cell growth. This discovery is worrying considering children ingest this dust. As per EPA, children take in about 60 to 100 milligrams of dust on a daily basis.

About 100 different chemicals in the samples of dust were present and 70 of these could accelerate the growth of fat cells. The researchers also said that these chemicals were present in high amounts in the dust samples which were collected from the homes where overweight or obese children lived.

Kassotis and his team are currently taking this research further to study the link between common household cleaning products and the growth of metabolic conditions.


It can be concluded that a factor that chips in obesity is dust. Dust particles contain chemicals which can disrupt the endocrine system and trigger the growth of fat cells. This can cause obesity. This is worrisome because children ingest this dust.

Researchers behind this study are working on it further to be able to find the link between cleaning products which introduce the chemicals with the development of metabolic conditions.
