Abstract in brief

  • The systematic review highlights that exposure to natural environments, especially through inhalation of natural substances, generally has positive effects on the immune system, including reduced inflammation and increased activity of natural killer cells.
  • The reviewed studies found evidence for health benefits like anti-inflammatory, anti-allergic, and anti-asthmatic effects, but some limitations in study design create uncertainties about the consistency and size of these effects.
  • Key areas needing further research include understanding the optimal duration of exposure, the specific roles of different types of vegetation or ecosystems, and improving study quality to confirm these immune benefits more reliably.]
