We’ve said before that having a plant on your desk can improve your thinking and focus. That’s because being within eyeshot of something from nature triggers the release of positive brain chemicals that make you feel refreshed and recharged. Well, there’s even more to it than that. By afternoon, indoor air pollution is at its peak. And according to Johns Hopkins University researchers, those chemicals increase brain inflammation – which produce feelings of anxiety. But if you have a plant on your desk, it’ll absorb the pollutants and pump out oxygen, which can leave you feeling calmer. And one of the best plants you can get is a spider plant. It thrives indoors – is hard to kill – and within 24 hours, it’ll soak up 87% of airborne pollutants in the immediate area. And not just carbon dioxide. It’ll eliminate dangerous volatile organic compounds – like benzene, ozone, and formaldehyde – that are emitted by plastic, fabric, computer printers, and cleaning solvents.
