The Short Sleep Study: A non-interventional study of fecal microbiota in Natural Short Sleepers
This research study explores the unique gut bacteria of “Natural Short Sleepers”—rare individuals who sleep less than average yet wake up feeling refreshed without daytime fatigue. By studying their gut microbiome, we aim to uncover insights that could help improve health outcomes for people with inadequate sleep.
As a participant, you’ll maintain your normal sleep habits, with no treatments, no overnight visits to a sleep clinic, and no interventions required. Eligible participants will receive up to $300 and an Oura Ring (yours to keep, ~$300 value) in appreciation for their time and commitment
