Effect of mindfulness meditation protocol in subjects with various psychometric characteristics at high altitude

Incidence of high altitude-related sickness is increasing due to more number of people visiting the areas of high altitude which may result in life-threatening conditions including acute mountain sickness (AMS), high altitude pulmonary edema (HAPE), high altitude cerebral edema (HACE), and High-altitude pulmonary hypertension (HAPH). We hypothesized that an advanced yoga regimen may be beneficial in dealing with the physiology of acclimatization.

Anthropometric, Biochemical, and Psychological assessments were carried out in 48 participants before and after the advance meditation program (AMP) in the experimental group. Individuals with an age range of 20-65 years with no comorbidities were included in the study. Participants were exposed to AMP for 4 days. All assessments were carried out at the baseline and after the course. Prakriti was constituted for all participants using a standard questionnaire. The study was carried out after obtaining the written informed consent as per the guidelines outlined by the Institute Ethics Committee.

Po2 and glucose levels were found significantly reduced along with changes in the Happiness index, anxiety, and mental well-being. However, participants with lowered Po2, after 4 days of mindfulness intervention, showed a positive outcome measured by the established scales of anxiety, happiness, and information processing. Psychometric or Prakriti wise analysis revealed that subject with "Pitta" constitution exposed to high altitude and advance meditation showed changes in more parameters than "Vatta" or "Kapha" Constitution.

Advance meditation in the high altitude zone confers biochemical and neuro-cognitive benefits. Molecular studies may require to understand the role of hypoxic condition in improving the disease state.
