How do we know how much sleep we actually need? Are devices like the FitBit accurate at tracking what stage of sleep we’re in, according to heart rate? How does substance abuse contribute to nightmares? In this episode of the NEI Podcast, psychiatrist and sleep researcher, Dr. Jade Wu answers these questions and so much more! Learn about her cutting-edge research in Part 1 of this episode. Dr. Jade Wu is a licensed clinical psychologist, sleep researcher, and host of the Savvy Psychologist podcast. She is a frequent guest on popular radio and podcast shows such as NPR, and quoted in popular press publications like New York Times, NBC News, and Huffington Post. Her current research focuses on treating sleep disorders in those with chronic illness. In the clinic, Dr. Wu uses evidence-based non-medication treatments to help people improve their sleep (and wake). Her approach is grounded in both science and compassion, so that her clients are empowered to live healthier and more fulfilled lives.  My website: www.JadeWuPhD.com Twitter: @JadeWuPhD Resources can be found on her website under the "Resources" tab.
