Did you know that spending time in a forest activates the vagus nerve, which is responsible for inducing calm and regeneration? Or that spending just one single day in a wooded area increases the number of natural killer cells in the blood by almost 40 percent on average?We've all had an intuitive sense of the healing power of nature. Clemens G. Arvay's new book brings us the science to verify this power, sharing fascinating research along with teachings and tools for accessing the therapeutic properties of the forest and natural world.
