It is the one period of time in which we're not doing these duration, path and outcomes types of analyses. It is critically important to all aspects of our health, including our longevity. Getting better at sleeping involves much more than just how much we sleep. We need to pay attention to sleep quality, accessing deep states of nondpo thinking, and accessing the right timing of sleep.
