Breathing polluted air causes to brain impairment: Research

According to a new study, breathing in dirty air might cause hazardous particles to be transferred from the lungs to the brain. A team of specialists from the University of Birmingham and Chinese research institutes conducted the study, and the results were published in the Proceedings of the National Academy of Sciences publication.

The hazardous particles, according to the study, travel through the bloodstream and may lead to brain problems and neurological damage. A probable direct channel followed by numerous inhaled tiny particles has been uncovered by scientists.

As previously stated, these poisons migrate through blood circulation, with evidence that once there, the particles linger in the brain longer than in other major metabolic organs.

The researchers discovered numerous tiny particles in human CSF fluids obtained from individuals with brain problems, revealing a mechanism that might result in dangerous particulate chemicals ending up in the brain.

“There are gaps in our understanding of the damaging consequences of airborne fine particles on the central nervous system,” said co-author Professor Iseult Lynch of the University of Birmingham. This study gives fresh information on the relationship between inhaling particles and how they migrate about the body.

The findings implies that up to eight times as many fine particles may reach the brain via the circulation from the lungs as pass directly via the nose, giving fresh evidence to the association between air pollution and the harmful effects of such particles on the brain.”

Air pollution has a variety of hazardous components, but particulate matter (PM), particularly tiny particles like PM2.5 and PM0.1, is the most dangerous in terms of creating adverse health impacts. Ultrafine particles, in particular, can bypass the body’s defensive mechanisms, such as sentinel immune cells and biological barriers.

Recent research has also found a relationship between high levels of air pollution and neuroinflammation, Alzheimer’s-like alterations, and cognitive difficulties in the elderly and children.
