Sleep Recordings from Wearable Devices in Meditators

The dataset comes from a study assessing the impact of meditation on sleep
quality and brain health.

DESIGN: A prospective single-site cohort study (conducted August 25th, 2021,
through September 26th, 2021) of meditators attending a retreat at the Isha
Institute of Inner Sciences, McMinnville, Tennessee.

PARTICIPANTS: Current U.S. adult residents attending Isha Institute's "Samyama
Sadhana" retreat (September 1st-5th, 2021) were contacted before the program.
34 of 35 enrolled participants in this volunteer sample are included in the
analysis; one subject withdrew following the retreat. Two healthy comparison
groups and four comparison groups with varying degrees of age-related brain
pathology are included.
