Suffocating Panic Attacks: 'Fire' Is Making Your Heart Beat Violently

A panic attack, accompanied by suffocating palpitations, brings physical distress that is far too painful to dismiss merely as a 'disease of the mind.' Modern medicine explains this as a complex response of the brain and nervous system. The 'amygdala', a small almond-shaped structure in our brain, is the central region that detects danger and triggers fear responses. When facing stress or threatening situations, the amygdala immediately sounds an alarm and activates our body's fight-or-flight response. At this time, the hypothalamic-pituitary-adrenal axis operates, causing stress hormones such as adrenaline and cortisol to surge rapidly. These hormones drive the heart to beat violently, elevate blood pressure, and make breathing rapid and labored. Muscles tense up, and sweat glands become explosively active. Although all of this is an instinctive survival reaction, when such a response occurs excessively and unpredictably in the absence of any real threat, we experience a panic attack alongside overwhelming fear. Neurotransmitter imbalances are also identified as a significant cause. In particular, serotonin plays a vital role in emotional regulation, and disturbances in this serotonergic system can amplify anxiety responses. In addition, brain gamma-aminobutyric acid functions to stabilize nerves, so when GABA function declines, excessive neural excitation can provoke anxiety. Hyperactivity of the sympathetic nerve within the autonomic nervous system is another major cause of panic attacks. The sympathetic nerve prepares our body for emergency situations, but when activated unnecessarily, it triggers core panic attack symptoms such as palpitations and dyspnea. Chronic stress further sensitizes these brain systems, lowering the threshold so that panic attacks are triggered easily by minimal stimuli. From this modern medical perspective, the 'heart fire' described in Donguibogam can be interpreted as an insightful concept that comprehensively explains amygdala hyperactivity, hypothalamic-pituitary-adrenal axis dysregulation, neurotransmitter malfunction, and sympathetic hyperactivity. It reminds us once again that our body and mind are not separate, but deeply connected as one.
