Can changing your breathing pattern unlock altered states of consciousness?
In short: From 1970s rebirthing to modern psychedelic alternatives, breathwork promises to dissolve mental barriers. While proponents claim it can purge suppressed trauma, the physiological reality involves a dramatic drop in cerebral blood flow. Is this a profound healing modality or simply a way to induce lightheadedness?
Breathwork, including techniques like 'rebirting' devised by Leonard Orr in the 1970s, aims to influence mental and physical states through conscious breathing. Proponents, such as Jack Raso, describe it as a healing modality designed to dissolve 'limiting programs' stored in the mind. Some practices, like holotropic breathwork developed by Stanislav Grof, use rapid breathing to induce altered states of consciousness, serving as a non-pharmacological successor to LSD-based therapies. Practitioners often utilize 'sitters' to provide physical or emotional support during sessions. These sessions typically last about one hour, though individuals may also practice alone for shorter durations.
The physiological mechanism behind these shifts is increasingly understood through the lens of blood flow. High ventilation breathwork has been found to reduce cerebral blood flow by approximately 45.5%, leading to marked cerebral hypoperfusion. Similarly, circular breathing reduces carbon dioxide concentrations, causing hypocapnia. This triggers cerebral vasoconstriction, which can result in neurological symptoms such as dizziness, tingling in the hands or face, and even cramping around the mouth. This reduction in blood flow is linked to the state of hypocapnia, which is believed to occur during high ventilation techniques. Such physiological changes are associated with sensory alterations and paresthesia.
Despite the intense experiences, the scientific community remains cautious. A 2006 panel of over one hundred experts considered rebirthing therapy discredited, and critics like Margaret Singer and Janja Lalich have labeled such practices 'bizarre.' While a 202 or 2023 review suggested breathwork might help with stress and mental health, researchers urge caution due to limited evidence. Furthermore, certain conditions like cardiovascular disease, glaucoma, or seizure disorders are significant contraindications, and the Findhorn Foundation even suspended its programme following concerns that hyperventilation could trigger psychosis in vulnerable individuals. The practice of rebirthing specifically claims to release repressed childhood memories, particularly those from one's birth, though no scientific evidence supports the ability to remember such events. Experts note that any such resurfaced memories are likely false.
