The concept of qi in the Donguibogam aligns closely with how modern medicine views the regulatory functions of the autonomic nervous system and circulatory system. The dizziness felt when rising suddenly from a seated position is closely linked to orthostatic hypotension. Because blood pools toward the legs under the effect of gravity, blood volume reaching the brain momentarily drops. In a healthy body, the autonomic nervous system responds rapidly by raising the heart rate and constricting blood vessels, stabilizing blood pressure to keep the brain's blood supply steady. However, when this autonomic regulation falters or blood volume is low, the brain experiences a momentary shortage of blood and sends out a warning signal in the form of dizziness.
This autonomic nervous system imbalance can stem from common lifestyle factors such as stress, overwork, sleep deprivation, dehydration, and poor nutrition. Chronic stress hyperactivates the sympathetic nerve, straining the heart and impairing the constriction and relaxation of blood vessels. Irregular meals and dieting can interfere with blood volume and blood glucose control, contributing to dizzy spells. In particular, anemia caused by iron deficiency lowers the oxygen-carrying capacity of the blood, making it difficult to deliver sufficient oxygen to the brain even when the heart pumps steadily. In addition, chronic inflammation or endocrine disease such as hypothyroidism can affect blood circulation and energy metabolism, worsening dizziness.
Ultimately, qi deficiency in the Donguibogam encompasses a range of dizzy symptoms caused by compromised blood flow to the brain, involving disrupted blood pressure regulation, low blood volume, reduced oxygen delivery, and autonomic dysfunction. Rather than assuming the issue is simple anemia and relying solely on iron supplements, supporting your body's qi through the overall health of the autonomic nervous system and circulatory system can offer a more grounded approach.
