Studies have shown that houseplants are good for your health — and not for their visual beauty. They mostly do the opposite of what we do when we breathe: release oxygen and absorb carbon dioxide. This not only freshens up the air but also eliminates harmful toxins. Extensive research by NASA has revealed that houseplants can remove up to 87 per cent of air toxin in 24 hours. Studies have also proven that indoor plants improve concentration and productivity (by up to 15%), reduce stress levels and boost your mood — making them perfect for not just your home but your workspace, too.
