The Brainstem-Asthma Connection: How Upper Cervical Subluxations Impact Respiratory Health

Upper cervical subluxation can contribute to asthma by disrupting the normal function of the nervous system, particularly the brainstem and vagus nerve, which play a crucial role in respiratory control. When the atlas (C1) or axis (C2) vertebrae shift out of proper alignment, they can place pressure on the brainstem, interfering with nerve signals that regulate lung function, bronchial dilation, and immune response. This misalignment may lead to increased airway sensitivity, inflammation, and bronchial constriction—hallmarks of asthma.
