Only a few years ago, the phrase consumer sleep technology was synonymous with sleep trackers, devices that monitor your nocturnal behaviours to give you insights into the mysteries of your non-waking hours.

Fast forward to 2021, where we’re in the middle of an innovation explosion of all type of gadgets, wearables, apps, smart home technologies which not only track, but also actively attempt to promote better sleep.

In today’s episode we talk to friend of the podcast, Dr Michael Grandner about this important distinction between sleep technology that measures, and tech that intervenes in our sleep.

Plus we explore some of the latest science-backed sleep devices that utilise light, sound, temperature and other esoteric techniques with strange acronyms like PEMF, TDCS, all in the mission to improve our sleep.

Dr Grandner helps us to understand where the science is at with all of the latest sleep-tech trends, including digital sleep coaching, Sp02 monitoring, light therapy wearables, bed cooling tech,  and more.
