We tend to our autonomic nervous system, the pera sympathetic nervous system, begins to take over and we get sleepyand to help us fall asleep. So it would seem like if you measure the autonomic nervoussystem with his heart rate variability, you'd be getting a really good picture of what's going on in there. And it would be an indicator that if your heart rat variability was, i'll talk about what's good and what's bad with heart rate variability in terms of what you should be looking for.
