We describe general lessons one can glean about the effective dynamics of open quantum systems using holography. Specifically, we will argue that using holographic CFTs to provide thermal environments is a useful way to extract the broad physical principles. This turns out to be especially useful when the probe system long-lived gapless modes of the environment. To illustrate the ideas, we will also motivate a simple class of toy models that captures all the essential physics. As a corollary we also explain analytic properties of real-time thermal correlation functions.
