During the COVID-19 lockdown in India, people who practiced yoga reported less anxiety, stress, and fear, and had better coping strategies compared to those who did not practice yoga. Yoga practitioners also showed better physical ability, endurance, and sleep quality, while being less likely to use substances or eat unhealthy food. Among yoga practitioners, those who meditated had relatively better mental health. The findings suggest that incorporating yoga into daily routines may help reduce stress and improve immunity, potentially lowering COVID-19 risk if specific protocols are implemented through a global public health initiative.
Bhramari Pranayama, a yogic technique involving breath control and attention to a self-produced sound mimicking a bumblebee, is traditionally described as an aid to attain Samadhi, or contemplative absorption. This review examines ancient texts including Saivagama texts, Yoga Upanishads, Gheranda Samhita, and Hatha Yoga Pradeepika to understand how the sound vibrations from this practice may enhance consciousness. The authors detail the technique's features and discuss its suitability for spiritual practice, research, and potential therapeutic use.
