Brief 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.

Detailed Description:

The purpose of this research protocol is to determine the influence of an 8-week breathing intervention on cerebrospinal fluid (CSF) circulation among healthy participants using a non-invasive real-time phase-contrast magnetic imaging (RT-PCMRI) technique. This aim will be examined by studying the changes in each participant's pre- and post-intervention CSF flow dynamics using the non-invasive RT-PCMRI technique during two MRI scans (one before and one after the 8-week intervention).

The study protocol consists of 20 healthy participants (two groups; 10 in each group with different breathing practices) undergoing an 8-week intervention, and pre-and post-intervention outcome measures.

The two 8-week interventions will be guided by two separate certified experienced yoga teachers. Both interventions will consist of 60-minute weekly group on-site sessions (1day/week) with a 20-minute daily home sessions (in between on-site sessions; 6 days/week) using home-aid practice materials. Participants' respiration data will be objectively tracked using a wearable respiration tracker device.

Arm Intervention/treatment
Experimental: Breathing Group 1
Arm 1 will receive an 8-week intervention that consists of a set of breathing practices through 60-minute weekly group on-site sessions (1day/week) with a 20-minute daily home sessions (in between on-site sessions; 6 days/week).
Behavioral: Breathing Group 1
The 8-week breathwork intervention incorporates a set of breathing practices under the guidance of a certified yoga teacher.

Active Comparator: Breathing Group 2
Arm 2 will receive an 8-week intervention that consists of slow breathing practices through 60-minute weekly group on-site sessions (1day/week) with a 20-minute daily home sessions (in between on-site sessions; 6 days/week).
Behavioral: Breathing Group 2
The 8-week breathwork intervention incorporates a set of slow breathing practices under the guidance of a certified yoga teacher.




Primary Outcome Measures :
  1. CSF Flow Velocities [ Time Frame: Once before and after the 8-week intervention ]
    The changes in pre- and post- intervention CSF flow velocities will be measured using a non-invasive MRI approach.


Secondary Outcome Measures :
  1. Systolic and Diastolic Blood Pressure [ Time Frame: Once before and once after the 8-week intervention ]
    The changes in pre- and post-intervention blood pressure will be measured.

  2. Body Mass Index (BMI) [ Time Frame: Once before and once after the 8-week intervention ]
    The changes in pre- and post-intervention BMI will be measured. The BMI is derived from each participant's height and weight information.

  3. Respiration [ Time Frame: Respiration data will be collected when participants are performing the breathing practices during the weekly on-site sessions (60-minute/week) and daily home practice (20-minute/day) over the course of 8-week intervention. ]
    Respiration phases will be measured using a wearable respiration tracker to objectively track respiration of participants throughout the interventions.
