Yoga is famous these days for helping combat the stresses of modern life. How the ancient yogis of old knew all the particularities of the benefits of Yoga is still mind-boggling, but they knew. It wasn't haphazard. Either by Divine inspiration, or revelations from deep self-study, the sages knew what was happening in a Yoga practice.
Now that Yoga has been around awhile, science has studied and discovered some of Yoga's secrets, and one of the most fascinating revelations is that Yoga regulates the nervous system by increasing the body's ability to respond to stress. It's called VAGAL TONE.
