Effect of Yogic Pranic Energization Technique on Stress, Heart Rate Variability and Cognition in Healthy College Students - A Randomized Control Trial
(S-VYASA, 2026-05-13) Arudhra K; Anoop D S; Moodala Girishankara K S; Ranjinimurthy P
BACKGROUND
Yogic Pranic Energisation Technique (YPET) is a guided meditative practice in which one's
own prana Shakthi is used for energising the body. Thus, every part of the body will be
revitalised. This technique is mainly given to people who are suffering from cancer, chronic
fatigue syndrome, etc. This practice integrates deep relaxation, breath awareness, and
visualisation of pranic flow through the body, and is believed to regulate autonomic function.
It helps to strengthen the immune defence and to revitalise the entire body. It cleanses the entire
respiratory tract and purifies the subtle channels of Prana. The breathing will be balanced
through Nadishudhi Pranayama, which is one of the steps in this technique. This brings balance
and rhythm to the breathing pattern. Thus, there will be balance in the ida and pingala Nadi,
which in turn activates the sushumna Nadi through which the energy flows properly. Heart
Rate Variability (HRV) is assessed as the primary variable to see the autonomic changes in the
YPET group & Supine rest group before and after the intervention, and compare both the
experimental group and the control group. The Stroop test is used to assess cognition in both
the experimental and control groups.
AIM
The study aims to assess the effect of YPET on Heart Rate Variability, Cognition & Stress in
healthy college students.
OBJECTIVES
• Compare pre and post–changes in the YPET group
• Compare the experimental group (YPET) vs. the control group (Supine rest)
MATERIALS AND METHODS
Subjects:
• A total of 100 people in the age group 18-25 years were screened for the study.
Source of subjects:
• Students aged 18-25 years. (Students from S-VYASA University pursuing UG).
Sample size:
• Recommended total sample size was N=100 (Experimental group n= 35, Control group
n=35; Excluded n= 30).
Design:
The design of the study was Randomized control trial. A total of 100 participants were
screened, and 30 were excluded on the basis of exclusion criteria. 70 participants were
randomly assigned to both experimental and control groups using chit method. The total
duration of the intervention was 3 months. The data was collected before and after the
intervention.
Assessments:
• Primary Variable- Heart Rate Variability (HRV)
• Secondary Variable- Stroop test, Perceived Stress Scale (PSS)
Intervention:
• Participants in the experimental group practised the Pranic Energisation Technique for
30 days for 30 minutes.
• Participants in the control group rested in a supine position for 30 days for 30
minutes.
Results:
Of 70 Healthy College students, all the subjects completed the study. No adverse events were
observed during the study period. The mean ± standard deviation age in the PET group was
19.4 ± 1.91 years, whereas in the CG was 20.5 ± 1.72 years. Overall, the Study Group (PET
group) has shown significant changes in HRV, Cognition and PSS scores across all variables
in comparison to the Control Group.
Baseline HRV parameters in both groups did not show any significant difference. The students
paired t-test was used to find the changes within the group. Within the group analysis, the
intervention group has shown statistical significance (P < 0.05) in Average RR (P = 0.05) and
SD rate (P = 0.038), whereas the CG did not show any significant changes. The independent ttest
was used to find the changes between the two groups. It showed significant (P < 0.05) improvement in Average RR (P = 0.008) and Average rate (P = 0.02) in the PET group after
30 days of practice.
In the Cognitive Stroop test, the Accuracy rate and Reaction time in the study group showed
statistical significance (P<0.05), which is not shown in the Control group. Between-group
analysis showed that Accuracy and Reaction time were highly significant (P < 0.05).
In PSS, it shows that the PSS has significantly reduced after the Practice of PET than SR.
Conclusion:
The results of the study suggest that YPET significantly reduces stress, improves HRV, and
enhances cognition. It’s a safe, cost-effective intervention, useful for the student population.
A Pilot Randomised Crossover Study Comparing Deep Relaxation Technique and Raga Neelambari Music on Sleep Quality in Sleep-Deprived Young Adults
(S-VYASA, 2026-05-13) Soujanya Nandi; Harshit Khandelwal; Vaishali Mathapati; Titty George
BACKGROUND:
Sleep plays a crucial role in maintaining physical and mental health. However, many individuals experience poor sleep quality, increased daytime sleepiness, and fatigue due to stress and lifestyle factors. Non-pharmacological interventions such as relaxation techniques and music therapy have shown potential benefits in improving sleep-related outcomes. This study aimed to evaluate the effectiveness of Deep Relaxation Technique (DRT) and Raga Neelambari (RN) in improving sleep quality and reducing fatigue.
OBJECTIVES:
To evaluate and compare the effectiveness of Deep Relaxation Technique and Raga Neelambari on improving sleep quality.
TRIAL DESIGN:
1. To assess changes in sleep quality, daytime sleepiness, and fatigue before and after interventions using PSQI, ESS, and FSS.
2. To compare the effectiveness of DRT and RN in improving these outcomes.
3. To identify which intervention produces greater improvement.
METHODS:
A crossover interventional study was conducted on 40 participants. Participants received both Deep Relaxation Technique and Raga Neelambari interventions in two phases with a washout period in between. Each intervention was administered over a period of 5 weeks. Outcome measures including Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and Fatigue Severity Scale (FSS) were assessed before and after each intervention.
PARTICIPANTS: young adults aged 18-25 years, (N=40) with self-reported poor sleep quality (PSQI score more than or equal to 5), recruited from S-Vyasa university, Bangalore.
INTERVENTIONS:
Group 1: Deep Relaxation Technique (DRT)- guided muscle relaxation with breath awareness, 20 minutes/session, 6 days/week for 2 weeks.
Group 2: Raga Neelambari Music Therapy (RN)- pre-recorded classical Indian raga, 10 minutes/session, 6 days/week for 2 weeks. Both groups crossed over after a 7-day washout period.
OUTCOMES: Primary outcome: Pittsburgh Sleep Quality Index. Secondary outcomes: Daytime sleepiness scale (ESS) and Fatigue severity scale (FSS), assessed pre-mid-post interventions.
RESULT:
The Deep Relaxation Technique showed statistically significant improvement in sleep quality, daytime sleepiness, and fatigue (p < 0.001). In contrast, Raga Neelambari did not show significant improvement in any of the measured outcomes (p > 0.05). Between-group comparison revealed that DRT was significantly more effective than RN in improving ESS (p < 0.01) and FSS (p < 0.01), while PSQI showed improvement but was less significant after correction. Overall, DRT demonstrated superior effectiveness compared to RN.
CONCLUSION:
Deep Relaxation Technique is an effective non-pharmacological intervention for improving sleep quality and reducing daytime sleepiness and fatigue. It was found to be more effective than Raga Neelambari. These findings support the use of relaxation techniques as a simple, safe, and cost-effective approach for managing sleep-related problems.

Effect of Acupuncture on Haemoglobin and Fatigue Level in Anaemic Females.
(S-VYASA, 2026-05-07) Himani Jagdish Shahare; Sridevi. K.J
Background: Low haemoglobin levels are associated with reduced oxygen-carrying capacity of blood, leading to symptoms such as fatigue, dizziness, reduced physical performance and poor concentration. Conventional treatment mainly involves iron supplementation; however, side effects are common. Acupuncture has been suggested to improve blood circulation and stimulate physiological processes that may support haemoglobin production and reduce fatigue.
Aim: Evaluate the effect of acupuncture on haemoglobin levels and fatigue among anaemic females aged 20–24 years at S-VYASA, Bangalore.
Method: Participants with mild to moderate anaemia received acupuncture at selected points (GB39, UB17, LIV13, SP6) for 15 days. Haemoglobin levels and fatigue scores were assessed before and after the intervention to determine the effectiveness.
Results: A significant improvement in haemoglobin levels and reduction in fatigue scores were observed following the intervention.
Conclusion: Acupuncture may be an effective complementary approach for improving haemoglobin levels and reducing fatigue.

Effect of scalp acupuncture at Po-Shen and Shen -Hun on sustained attention in healthy young adults: A Pilot Randomized control trial
(S-VYASA, 2026-05-06) Mirunalini V.; Chandrika, Chaudhary; Monicaasun
Background:
In the current digital era, increased exposure to short-form media has contributed to a
reduced ability to maintain prolonged focus on tasks. Sustained attention is essential
for effective task performance and daily functioning. Scalp acupuncture, a non-
invasive approach from Traditional Chinese Medicine, targets specific regions such as
the Po-Shen and Shen-Hun bands associated with attention regulation. However, its
effect on sustained attention in healthy individuals remains insufficiently explored.
Aim:
The study aimed to evaluate the effect of scalp acupuncture at the Po-Shen and Shen-
Hun bands on sustained attention in healthy young adults.
Objectives:
The primary objective was to assess changes in sustained attention following scalp
acupuncture. The secondary objective was to evaluate changes in cognitive function
after the intervention.
Materials and Methods:
A pilot randomized controlled trial design was adopted. A total of 32 healthy
participants aged 18–25 years were recruited and screened using the Mini-Mental
State Examination (MMSE). Eligible participants (MMSE >27) were randomly
allocated into intervention (n=16) and control (n=16) groups. The intervention group
received scalp acupuncture at Po-Shen and Shen-Hun bands, while the control group
received sham acupuncture. The intervention was administered for two blocks of 10
consecutive days with a 5-day interval. Sustained attention and cognitive performance
were assessed before and after the intervention using the Sustained Attention Response Task (SART) and the Stroop Colour and Word Test (SCWT). Data were
analyzed using JAMOVI (2.7.26) Was used for statistical analysis.
Participants:
Thirty-two healthy young adults from a university setting who met inclusion and
exclusion criteria and provided informed consent were included in the study.
Study Design:
This study was a pilot randomized controlled trial with parallel groups and assessor-
based pre- and post-intervention evaluation.
Assessment Tools:
Sustained attention was assessed using the SART (sustained attention response task),
and cognitive function was evaluated using the SCWT (Stroop Colour and Word Test).
Intervention:
The intervention involved scalp acupuncture at the Po-Shen and Shen-Hun bands
using standard needling techniques, while the control group received sham
acupuncture at non-therapeutic points.
Hypothesis:
Scalp acupuncture would significantly improve sustained attention and cognitive
performance compared to the control group.
Null Hypothesis:
There would be no significant difference in sustained attention or cognitive
performance between the intervention and control groups.
