1Spending 90 minutes in a forest boosts immune antibodies more than cities.
2Mucosal antibodies increase, effectively preventing colds and respiratory issues.
3Try a light walk in a nearby forest this weekend to protect your health.
📖 Easy Explanation
🔍 Background
This study explores how our immune system physically changes in the forest, beyond just improving our mood.
📌 Key Points
A Japanese study on men aged 40-70 found that 90 minutes in a forest significantly raised mucosal antibody levels. These antibodies act as guards, blocking germs from entering through the mouth or nose.
💡 Why It Matters
As immunity declines with age, forest walks can be more effective than supplements. On low-dust days, visiting a forest protects respiratory health and reduces stress.
