Choose village life for a healthy life


Are you a hardcore fan of urban living? If so, you have better chances of getting all lifestyle diseases, though you think your surroundings are clean. It is not a belief anymore, but now it is a fact endorsed by research.

On the other hand, living in a jungle hut or rustic village will come with lots more positive effects.

Studies done by researchers at Rutgers and other universities found city homes are filled with industrial chemicals, cleaning agents and fungi that love warm, dark surfaces, while jungle huts had fresher air, more sunlight and natural materials with which humans evolved.

The impacts are also different on our health. Urbanization is associated with a reduction in infectious diseases, but also with a worldwide increase in obesity, asthma, allergies, autism and other disorders as well as a massive loss of diversity in the human microbiome, the beneficial germs living on and in our bodies.

The researchers compared microscopic materials in homes and people’s bodies, spanning the spectrum of urbanization in the Amazon basin. The locations included a remote Peruvian jungle village of thatched huts with no walls; a Peruvian rural town with wooden houses lacking indoor plumbing; a Peruvian city of 400,000 residents and more modern amenities; and the metropolis of Manaus, Brazil, which has a population of two million.

“Urbanization represents a profound shift in human behaviour. Modern living literally walls us off from the natural environment and shuts us in with industrial compounds, higher carbon dioxide levels and skin-loving fungi,” said senior author Maria Gloria Dominguez-Bello, a professor in Rutgers University-New Brunswick’s Department of Biochemistry and Microbiology and Department of Anthropology. “This study sheds light on how human-created environments affect our health and how we can think about improving them.”

The study found that the diversity of chemicals clinging to indoor surfaces increases dramatically with urbanization. Molecules derived from medications and cleaning agents were part of the interior environment of homes in the metropolis and city but not in the rural or jungle homes.

Although the urban dwellers reported cleaning more frequently, surfaces in their homes had a greater diversity of fungal species associated with human skin. This may be because the fungi have become resistant to cleaning products, the study said.

It may also reflect the urban homes’ warmer temperatures, reduced air exchange, lower levels of natural light and higher loads of human skin flakes. Samples from people in the different environments also found a greater diversity of foot fungus on the urban dwellers. Also, in the rural and jungle homes, the researchers found a greater variety of bacteria and fungi that live outside, and fewer species known for colonizing the human body.
