It’s easy to forget what we’re breathing indoors - but research suggests we shouldn’t. In one study, test performance dropped sharply when indoor CO₂ levels rose, even within what’s considered “safe” by current standards. And with schools and offices often poorly ventilated, this may already be affecting how we focus and process information.
Other research has tied air pollution to markers of cognitive stress - from attention challenges in children to neurological changes seen in both infants and the elderly.
While the long-term effects are still being studied, small actions like ventilating indoor spaces or adding air-purifying plants may help limit exposure to indoor pollutants - and give your brain more room to breathe.
