The air we breathe every day is not just a source of heaviness or allergies. According to a recently published scientific study, harmful substances in the air - nitrogen dioxide (NO₂) and PM2.5 particles - have a serious impact on the brain function of the elderly.
This was reported in a scientific study published in The Journals of Gerontology. The scientists' conclusion is very clear and alarming: air pollution reduces cognitive abilities, that is, weakens a person's ability to think, remember, speak and make decisions.
10-year analysis, more than 1,000 participants - the conclusions behind the large study
The study covered the period from 2008 to 2017 and involved 1,127 older people over 65. Many factors were taken into account, such as their age, place of residence, lifestyle and physical activity. Most importantly, the level of NO₂ and PM2.5 in the area where they lived was in the spotlight.
The results are not just analytical - they are based on facts that have been tested in practice:
- People living in polluted areas performed worse on cognitive tests.
- The biggest difference was observed in speech skills - finding words, pronouncing and expressing thoughts.
- The effect was even stronger in people living near industrial and fuel sources.
Air pollution is the "hidden enemy" of brain function
The interesting thing is that these harmful substances affect the human brain not in one day, but slowly over the years. Scientists call this a "silent attack on the human body."
Harmful substances that affect brain function are released into the air from fuel combustion, heating systems, and industrial activities. Many people do not even know that these substances are inhaled and reach the brain through the blood.
What to do?
The authors of the scientific study recommend the following to maintain brain health:
✅ Eat a diet rich in fruits and vegetables;
✅ Physical activity and intellectual exercises;
✅ Live or walk in areas with clean air as much as possible;
✅ Use air filters in the home.
Zamin.uz conclusion:
Brain activity does not depend only on age. In fact, the environment that surrounds us determines the quality of our future. Whether every particle of air you breathe will be a pleasant energy for your brain or a quiet disaster - you need to know this in time.
For a "mind-free" old age, action must start today. A healthy brain is a guarantee of a healthy life.
Do you live in a place with clean air? In general, what do you think about such studies?
