Research findings:
- The length and the strength of slow waves matter
- Intervention during slow wave sleep can enhance slow wave activity
- Acoustic stimulation found to be an effective way to increase SWA
Research findings:
The system uses auditory stimulation to enhance slow wave sleep without causing arousals.
SmartSleep is for patients who are mildly sleep-restricted, but do not suffer from serious sleep conditions such as insomnia or obstructive sleep apnea †.
SmartSleep was founded in 10 years of sleep research by industry leading experts and supported by four years of Philips research and development. Since its inception, Philips has worked closely with a scientific advisory board made up of world-renown sleep physicians and scientists. These experts have played a vital role in SmartSleep’s end-to-end innovation, advising Philips development teams on the science behind the functionality, as well as the design and analysis of experimental trials of SmartSleep in the laboratory and in the home.

In fact, the need for and approach to developing SmartSleep was primarily born from extensive research by Dr. Giulio Tononi showing that sleep slow waves can be enhanced by the delivery of auditory stimuli. His 2010 paper was a critical catalyst in the conceptualization of SmartSleep as an innovative device to use tonal stimulation to improve deep sleep quality in those who do not get enough sleep due to lifestyle.
At Philips, we see an opportunity to leverage advanced technology, coupled with scientific and consumer insights, to deliver solutions that improve people’s health and drive differentiated outcomes across the health continuum. Our scientific advisory board and the guidance they offer allow us to continue to improve lives through meaningful innovation that is truly rooted in science.
