“Irene had a great interview at the Sleep Super conference. She mentioned the low tone dorsal for rest digest and the high dorsal tone, which is freeze, and the sympathetic system activated at the same time. I'm a bit confused about high and low tone dorsal. Is this the same as high and low vagus tone? And I have heard that you should have a high vagus tone because then you are more balanced. Doesn't a high vagus tone that is good contradicts the high dorsal tone, which is bad?”
