Visiting a forest can induce a significant increase in both the number and activity of natural killer cells, one of the ways our body fights off cancer. Researchers found a significant boost in natural killer cell activity in men and women after they spent a weekend walking in the woods. The same results were even seen after just a one day trip to the woods, and the natural killer cell activity was still boosted a week later. In a study comparing walking in a city versus a forest, 80 percent of the subjects walking in the woods experienced a boost in natural killer cell activity, compared to only one in ten of the city walkers. Moreover, researchers found that the increased natural killer cell activity lasted up to 30 days after the stroll in the forest.

Can the aroma of wood essential oils replicate the immune boosting effects of walking in a forest?

In my Daily Dozen, I recommend that you strive for a minimum of 90 minutes of moderate or 40 minutes of vigorous exercise every day. Next time you take a walk, try to go to the forest or a wooded park for the added benefits of boosting your anticancer immunity. https://nutritionfacts.org/daily dozen/ How Not to Age is out now https://see.nf/HNTABook.
