# Toxic Air Harms Not Just Lungs But Also Heart, Brain and Nerves, Explains Doctor > Air pollution is often viewed as a respiratory issue, but experts warn it damages vital organs including the heart and brain. Dr. Prashant Saxena from Artemis Hospital in Gurugram explains how toxic air affects the entire body. **Type:** article · **Category:** Health · **Published:** 2026-10-28 · **Source:** TrendKia **Canonical:** https://trendkia.com/en/health/toxic-air-harms-not-just-lungs-but-also-heart-brain-and-nerves-explains-doctor-52523 · **Language:** English **Tags:** air pollution, heart health, brain stroke, Dr Prashant Saxena, PM 2.5, health news Air pollution is frequently restricted in our minds to breathing troubles and lung-related ailments. However, toxic air impacts several critical organs throughout the human body. Dr. Prashant Saxena, chairperson of respiratory diseases, critical care, and sleep medicine at Artemis Hospital in Gurugram, explains how polluted air damages the heart, brain, and nerves. ## How Pollution Harms the Heart and Brain - Remaining exposed to polluted air over long periods triggers inflammation inside the body and increases oxidative stress. This impacts the functioning of blood vessels, causing blood pressure to rise gradually. High blood pressure places extra strain on the heart, raising the risk of heart attacks and strokes, particularly among individuals already battling hypertension and heart disease. Additionally, air pollution can affect the inner lining of blood vessels, reducing their flexibility and increasing the danger of plaque accumulation within the arteries. - Extremely fine pollutant particles like PM 2.5 present in the air enter the body through respiration, moving past the lungs and directly into the blood vessels. This process can inflict severe damage on brain health. Particularly, long-term exposure to contaminated air exerts adverse effects on neurological well-being over time. ## How to Protect Yourself from Air Pollution Check the AQI of your locality before stepping out of the house. Use an air purifier inside your home. Avoid going outdoors when pollution levels outside are extremely high. Whenever you must step out, make sure to use a mask. Refrain from going out for workouts during early morning or evening hours when pollution is high. Keep your body hydrated to help flush out toxic substances that enter the system. Wash your hands and face thoroughly after returning home from outside. Keep indoor plants like spider plants, snake plants, or peace lilies inside the house, as they help purify the air naturally. ## What this means for you This severe crisis regarding toxic air exerts a direct practical impact on the health of ordinary citizens across the country, particularly those vulnerable to cardiovascular and neurological conditions. - **Across India:** Millions of residents living in polluted urban centers face heightened risks of respiratory and cardiac complications during seasonal smog spikes. This often leads to a surge in hospital admissions for heart and stroke patients. - **In Gurugram:** Local residents and commuters in the surrounding urban areas must regularly monitor local AQI levels before heading outdoors and incorporate protective measures like masking into their daily routines. ## Why this happened Several environmental and physiological mechanisms explain why and how polluted air inflicts systemic damage on major human organs. - **Infiltration of PM 2.5 Particles:** Extremely fine pollutants in the contaminated atmosphere bypass the natural filtration defenses of the lungs and enter directly into the bloodstream. - **Oxidative Stress and Inflammation:** Prolonged inhalation of toxic air triggers internal inflammation within the body, damaging vascular tissues and arterial pathways. - **Blood Pressure Elevation:** Pollutants reduce the flexibility of blood vessels over time, increasing vascular resistance and driving up blood pressure levels. ## Questions & Answers ### 1. Does air pollution affect only the lungs or other organs too? Pollution does not remain limited to the lungs; it causes serious damage to the heart, brain, and blood vessels as well. ### 2. How does polluted air affect the heart? Prolonged exposure to polluted air increases inflammation and oxidative stress in the body, leading to elevated blood pressure and a higher risk of heart attacks. ### 3. How do PM 2.5 particles enter the body? Extremely fine particles like PM 2.5 enter through respiration into the lungs and from there pass directly into blood vessels, reaching the rest of the body and the brain. ### 4. Which plants can be kept indoors to purify the air? Indoor plants like spider plants, snake plants, or peace lilies can be kept inside the house as they help purify the air naturally. ### 5. What precautions should be taken outdoors to avoid pollution? Check the AQI before stepping out, wear a mask, and avoid exercising outdoors during early morning or evening hours when pollution is high. --- _TrendKia — Har trend, sabse pehle..
