Sleep is one of the most critical functions of the brain, yet one in three adults gets an unhealthy amount of sleep, affecting performance, recovery, mental health, and long-term neurological well-being.

In this episode of Marni On The Move, Marni is joined by Tim Rosa, CEO of SOMNEE, a company transforming sleep and unlocking peak neurological health to improve the human experience.Built on decades of neuroscience research, SOMNEE uses advanced EEG+ brain sensing and tACS neurostimulation technology to personalize sleep optimization—going far beyond traditional sleep trackers by working directly with the brain.
