TT: This Boosts Your Immune System by 80% in 3 Days (And Lasts 30 Days)

Spending time in nature feels good—but what if it could also strengthen your immune system in a powerful way?

On today’s episode, I want to share with you some fascinating research on a simple activity that can significantly increase natural killer (NK) cells, helping your body fight off viruses, reduce inflammation, and even protect against cancer.

So join me on today’s Cabral Concept 3464 to learn how you can boost your immune system by up to 80% in just 3 days.

Enjoy the show—and as always, I’d love to hear your thoughts!

Show Highlights & Big Takeaways:

1. What Did the Study Show
The study showed that spending just 3 days and 2 nights in nature can increase natural killer (NK) cell activity by up to 80%, boosting your body’s ability to detect and fight off viruses and cancer cells—even without prior exposure.

2. Trees Emit Healing Compounds
Natural aromatic compounds like alpha-pinene, beta-pinene, and limonene released by trees (especially pines) enhance NK cell activity and promote anti-cancer protein production in the body. The immune-boosting effects can last 7 to 30 days after your time in forest.

3. What Are Natural Killer Cells
Natural killer cells are part of your immune system and act like your body’s front-line defense. They help spot and destroy harmful cells—like viruses and cancer—before they have a chance to spread.
