If you wonder how the SmartSleep waves work, please find here if we can answer your questions.
Is SmartSleep sending waves into my brain?
Nope! The sensors on your SmartSleep are collecting the brain activity that you are naturally generating. They are not sending anything in. They are only “receivers of outgoing information” from you – like a heart monitor. The Sleep Boost provided by SmartSleep is delivering sounds to stimulate your brain the way any sound you encounter during the day would do – except the sounds that SmartSleep makes are at a scientifically validated volume and frequency to create the sound or tone to improve your sleep quality.
