The Role of Sleep in Making Meaningful Decisions

There had been a lot of literature to suggest that sleep was really important for the kind of making sense of the information. And so I ran some analyses and tried to understand this index called heart rate variability or this idea that our heart rate isn't consistent. Now, if you have a lot of variance in your heart rate, what that really means is that the underlying physiological structures that are controlling your heart rate can very actively come in and out of that control.
