The Science of Recharging Your Energy with Sara Mednick

If you’re like me, you may have a case of email apnea, where you stop taking restful breaths when you open a work email. Or maybe you’re in the habit of shining blue light into your eyes long after sunset through your phone. Many of us are doing all kinds of things throughout the day that put us in a constant state of fight or flight arousal, with long-term impacts on health, productivity and happiness.My guest for today’s episode is Sara Mednick, author of The Power of the Downstate, a book about the art and science of rest and relaxation – why it’s so important, the best ways to go about getting more of it, and the time of day when our bodies are biologically suited to get the most benefits from it. As a cognitive neuroscientist at the University of California, Irvine, Mednick has a great scientific background on this topic. Read her bio here.
