Clinical studies show that Hyperbaric oxygen therapy can rapidly relieve acute migraine pain for some people by constricting dilated blood vessels and reducing brain inflammation.
How HBOT Affects Migraines:
Pain relief: Breathing pure oxygen under pressure helps stop acute headache pain during an attack.
Vessel constriction: High-pressure oxygen acts as a natural vasoconstrictor to calm swollen blood vessels.
Lower inflammation: It decreases chemical swelling and inflammation in the brain
Decreased: blood vessel spasms
Generation: of new blood vessels
Study: Normobaric and hyperbaric oxygen therapy for migraine and cluster headache
Conclusion: There was some evidence that HBOT was effective for the termination of acute migraine in an unselected population.
Study: A preliminary report on hyperbaric oxygen in the relief of migraine headache
Conclusion: One of the 10 patients in the normobaric group achieved significant relief of headache symptoms, while 9 of 10 in the hyperbaric group found relief. Based on a chi-square test, this difference is significant at the P < .005 level. The results suggest that hyperbaric (but not normobaric) oxygen may be useful in the abortive management of migraine headache.
