Chiropractors help with respiratory issues by ensuring proper spinal alignment, especially in the thoracic region, which can impact breathing. Misalignments can compress nerves, restrict chest expansion, and cause muscle strain, leading to breathing difficulties. Through spinal adjustments, postural exercises, soft tissue therapy, and breathing techniques, chiropractors can improve lung capacity, reduce stress on the diaphragm, and promote relaxation, enhancing respiratory function.
