Study Summary
The purpose of this research study is to determine the influence of yoga breathing practices on cerebrospinal fluid (CSF) circulation, and to find out primarily if a regular practice of 8-week yoga breathing would enhance CSF circulation as well as if the intervention would improve participant's quality of life, quality of sleep, and reduce existing stress. Participants will be randomized into two arms for different breathing practices.
Primary Outcome
We have collected cerebrospinal fluid (CSF) flow measurements during a set of breathing practices while subjects were inside the MRI scanner. MRI-based CSF flow was quantified at the level of Foramen Magnum. Data processing included the extraction of velocity waveforms of the CSF motion ( i.e, CSF velocity in cm/s) and subsequent analysis of CSF velocities across different breathing conditions. Positive CSF velocities indicate fluid motion in the cranial (upward) direction, whereas negative velo
