The new funding opportunity aims to develop closed-loop technologies that objectively measure and adaptively correct poor sleep at home. Key takeaways:The Restorative & health-Enhancing Sleep Time (REST) program will fund the development of closed-loop, in-home sleep technologies. The Advanced Research Projects Agency for Health (ARPA-H), an agency within the US Department of Health and Human Services (HHS), recently introduced the Restorative & health-Enhancing Sleep Time (REST) program. “Poor sleep is contributing to almost every chronic disease we’re fighting in this country, including dementia, depression, diabetes, and heart disease,” says Alicia Jackson, PhD, director at ARPA-H, in a release. “REST is designed around a simple but ambitious premise: we can more accurately measure sleep quality at home and correct it in real time.
