Greater exposure to plants, particularly of diverse and native species, may support immune health. In a study of nearly 50,000 children in New Zealand, children who were exposed to more vegetation were 6% less likely to develop asthma, and children who were exposed to greater plant diversity were 6.7% less likely to develop asthma.
