What are the best for staging deep sleep and helping keep the brain in it?
Nathan Whitmore has small vibrations for it
There’s nextsense.io
Galeo cofounder in fascia.ai now. Fascia has a very comfy sleep staging wearable
https://frenzband.com/ [the EEG is really easy to put on]
fascia.ai [ also easy to put on but BtoB]
Traumschreiber [Institute of Sleep and Dream Technologies - sd20.org] - this is cheapest, will be released later this year
hanein lab has a sleep mask [sharon yacim]
some ppl who get muse s also get access to raw data through developer tools [one contacted interaxon for this]
Some play loud noises right before (or during) sleep to help maintain deep sleep [or induce lucid dreaming]
