Polluted air affects weight gain

Chemicals in polluted air cause weight gain. Researchers from the University of California discovered that there is a connection between pollution and obesity. They followed more than 2300 American children from early childhood and discovered that at the age of ten, youths exposed to higher traffic pollution averaged about four pounds [1 kg] more than children living in clean air.

Child lungs scans showed that weightiers living in more polluted areas had far more signs of physical lung damage. Scientists believe that polluted air causes a deterioration of inflammatory reactions in the body. First, polluters irritate small air bags in the lungs, placing a stress response that involves releasing hormones. These reduce the body's ability to absorb energy (or glucose) from food, leaving sugar levels in uncontrolled blood. When blood sugar levels are unstable, mood swings increase.

The contaminants also cause the release of molecules called citotoina, which send the immune system to overload, causing inflammation in the brain and body. Rat studies have shown that this brain inflammation can lead to overuse. Trucks, buses, and oil cars are especially harmful because of the amount of nitrogen oxids released. Nitrous options can develop into microscopic molecules known as particles (PM), which further irritate the lungs. These are wearing chemicals, so when you suck them, keep a collection of irritators deep in your lungs. After they go to blood, they cause damage to the walls of blood vessels, leading to heart disease and stroke. /Intv
