Problem: City life takes away microbial diversity. Pollution, sterile environments, and lack of nature exposure weaken our microbiome. Studies link this to higher inflammation, which disrupts serotonin and dopamine balance - fuelling stress, anxiety, and sudden anger waves. Solution: Forests are rich in airborne microbes that restore microbial balance. Inhaling these bacteria reduces inflammation, stabilizes neurotransmitters, and calms the nervous system. Action: Deep breath. Forest air. Microbial reset. Science-backed mood control.
