You already know pollution affects your lungs — but here’s the part most people miss: it’s also quietly raising your blood sugar and blood pressure.

Tiny particles floating in polluted air, called PM2.5, are so small they move from your lungs straight into your blood. Once inside, they cause inflammation and insulin resistance — two triggers that can lead to diabetes and hypertension.

What Indian data is showing

A long-term study from Delhi and Chennai found that people exposed to higher PM2.5 had higher fasting glucose levels and a greater chance of developing type 2 diabetes.
Other global analyses show India’s huge population and high pollution levels make this link especially serious.

Why this matters

Most of us don’t realize air pollution isn’t just about breathing — it’s about metabolism.
When your body’s under constant oxidative stress, everything from your heart rate to your insulin response gets thrown off.

What you can do right now

• On smog-heavy days, work out indoors or walk at low-AQI hours.
• Ventilate your home — use exhaust fans, open opposite windows.
• Add plants or purifiers where you can.

Ask your campus or office to share AQI updates and schedule outdoor activities smartly.

What institutions can change

Public displays of air quality, indoor air monitoring, and tying wellness screenings to poor-air periods could help catch risks early.

Urban wellness isn’t about perfection — it’s about knowing the risks that don’t show up right away.
