Improve your air
Planting trees and hedges (outside); growing houseplants (inside)
WHY NASA, when experimenting with plants to clean air in space stations, found that one plant per 100 sq. feet was enough to reduce indoor pollutants such as formaldehyde and carbon monoxide. Spathiphyllum ( peace lily) absorbs the widest range of chemicals. Outside, urban trees like holm oaks absorb particulates and nitrogen dioxide. Dr Alistair Griffiths says careful planting maximises the effect. “Plant in different layers – trees first, then shrubs,” he says. “And don’t have a fence; plant a hedge instead.”
DID YOU KNOW? Office workers who have houseplants on their desks are 15% more productive than those who don’t.
