Breathing and the brain: Pranayama, an ancient self-directed approach to neuromodulation.

Pranayama, the ancient yogic practice of breath control, acts as a natural method of neuromodulation by influencing autonomic functions, brainwave patterns, and neuroendocrine responses. Evidence from clinical, neuroimaging, and psychophysiological studies shows that techniques such as slow breathing, rapid breathing, and unilateral nostril breathing stimulate the vagus nerve, regulate the autonomic nervous system, and shift hemispheric brain dominance—mechanisms similar to contemporary approaches like transcranial magnetic stimulation and vagus nerve stimulation. Pranayama offers an accessible, self-directed alternative for managing stress, enhancing cognition, and promoting emotion regulation. Significant knowledge gaps remain, including the need for well-powered, randomized-controlled studies to understand durability of effects, optimal protocols, and mechanisms of action.
