Cyclic Meditation for Sleep 2014


Study Objective: To study the effect of Cyclic meditation (CM) on the quality of sleep for people with anxiety and high work related stress among adults. 

Primary Hypothesis: CM may improve the quality of sleep for people with anxiety neurosis and high work related stress. 

Secondary hypothesis: Regular practice of CM reduces the risk of hypertension, better control of blood sugar levels in those with diabetics and improves overall medicine and symptom scores for people with minor health conditions.

Subjects: Normal healthy volunteers with a age range 30-65 and patients with anxiety issues, Insomnia, Snoring, Sleep apnea, Hypertension, Diabetes mellitus type II and such other metabolic disorders) would be recruited from the community.

Intervention: A 4-week, daily practice of a given session of recorded CM practice session. Volunteers will undergo training and practice of CM at their respective homes for a period of 4 weeks. They will also attend one yoga class per week conducted by a Yoga Bharati certified yoga teacher. 

Outcome measures (pre and post intervention) 
• Standard Anthropometric measures including height & weight, BMI will be calculated. 
• Clinical vitals viz., - Blood pressure, Pulse rate, , Respiratory Rate, Breath Holding Time and Bhramari time [to measure expiratory volume] 
• Performance test viz., Flexibility assessed using Sit and Reach box
• Brief Case History to record the presence of anxiety issues, Insomnia, Snoring, Sleep apnea, Hypertension, Diabetes mellitus type II and such other metabolic disorders)
• State and Trait Anxiety Inventory (State X1)
• Pittsburg Sleep Scale
• Perceived Stress Scale (PSS)

Compulsory Daily Log
• Stanford Sleepiness Scale

Background and rationale:
Yoga has shown to reduce stress levels and improve quality of sleep. Cyclic Meditation [CM] is a technique of 'moving meditation', which combines the practice of yoga postures with guided meditation. This technique is developed Vivekananda Yoga Research Foundation, Bengaluru (VYASA). The technique has its origin in an ancient Indian text, Mandukya Upanishad. All meditations, irrespective of the strategies involved are believed to help reach the state of dhyana – an uninterrupted flow of consciousness without the distraction of the mind. There are several strategies in CM that include breath awareness, awareness of internal sensations that makes it applicable to people with different tendencies such as rajasic (hyperactive mind), tamasic (sluggish mind) or satvic (balanced mind). In CM, the period of practicing yoga postures constitutes the awakening practices, while periods of supine rest comprise calming practices. An essential part of the practice of CM is being aware of sensations arising in the body. This supports the idea that a combination of stimulating and calming techniques practiced with a background of relaxation and awareness (during CM) may reduce psycho physiological arousal more than resting in a supine posture for the same duration. 
A detailed study report on different studies of the psycho-physiological effects of CM are found in International Journal of Yoga Therapy [2009 vol2 issue 2]

Pre-study Assessments: 2-3 days before the intervention
