Can Houseplants Affect Human Intelligence?

Owning a houseplant can increase your attention span. This is because humans have a limited capacity to focus, and looking at a houseplant, or simply nature in general, appears to help rejuvenate that capacity. Though just how houseplants affect intelligence is still debated, it's clear that having one around can improve your thinking process.

More facts about houseplants:

  • Houseplants have many effects on health, too. Multiple studies show that simply being near a houseplant can lower your blood pressure by as much as six points, and houseplants also can significantly reduce the amount of carbon dioxide and other pollutants in a house.

  • African violets, orchids, dracaenas and ficii are among the most popular houseplants in the world.

  • People appear to be designed to relax around greenery — the color alone naturally creates a relaxation response.
