Dr. Qing Li spent 20 years understanding: the forest heals us at a molecular level. 🌲

Trees release phytoncides — natural compounds we inhale during a walk. His research proved: these substances lower cortisol (stress hormone) and simultaneously activate NK cells — our immune system's natural killers that fight viruses and abnormal cells.

One experiment showed a shocking result: just two days in the forest boosted NK cell activity for up to 30 days. This isn't magic — it's a measurable impact of nature on your body.

Step outside. Breathe. The forest is waiting.
