Sleep Need & Sleep Age: Find Out Yours – Dan Gartenberg : 583

Dan Gartenberg, Ph.D., wants you to sleep better, so he’s conducted research and developed technology based on the science of sound, light, temperature, and relaxation to help you do just that. “By more accurately measuring sleep, based on your sleep stage, there are ways of enhancing your deep sleep in real time while you’re sleeping through sound or temperature stimulation,” he says.

Dan, aka Dr. Snooze, is the co-founder and CEO of Sonic Sleep and also an adjunct assistant professor at Penn State University. With a background in cognitive psychology and expertise in sleep, A.I., and preventive health, he has spent most of his career focused on improving sleep health.

In this episode of Bulletproof Radio, you’ll learn:

  • why “sleep need” includes both quantity and quality;
  • how you can discover your “sleep age;”
  • what you can do to get more out of your sleep; and
  • which sleep hacks really work.
