This is so exciting I had to take a break and post it. Not very long ago, research led scientists to define what they call the inflammatory reflex which connects the immune system directly with the nervous system.
And in 2002 they discovered that the brain controls the immune system via the vagus nerve (which runs throughout the body’s organs). And now, ta-dah: They now have a way to test scientifically the effects that such ancient Indo-Tibetan practices as yoga and meditation have on the activity of the vagus nerve. Read this very clear explanation here. Oh, I love being alive in these times.
