Most Indians worry about outdoor pollution, but the truth is that the air inside our homes can be far more dangerous. Indoor air often contains higher levels of PM2.5, VOCs and trapped pollutants from wood, polish, fragrances, cleaning liquids and repellents toxins we breathe for hours every day without realising it. In this conversation, indoor air expert Barun Aggarwal, CEO of BreatheEasyLabs, explains why indoor air can be worse than Delhi’s pollution, how airtight modern homes intensify the problem, and why CO₂, ventilation, and chemical off-gassing quietly affect sleep, focus, immunity and long-term health. He breaks down the four pillars of indoor air quality in simple, practical terms and shows how small changes can have a big impact. If you’ve been feeling tired at home, struggling with sleep, or noticing recurring health issues in your family, this episode cuts through the noise and gives you real clarity on what’s happening inside your living space and how to fix it.
