Shoulders Stiffening Whenever You Are Stressed? Press 'Here'

Dear readers, do you think that shoulders and neck stiffening under stress is merely a psychological phenomenon? It is not. Our body responds to stress in a very sophisticated and scientific manner. At the core of this response lies a complex brain-nerve-muscle interaction. When placed under chronic stress conditions, the hypothalamic-pituitary-adrenal axis in our brain becomes excessively activated. This increases the secretion of the stress hormone cortisol and excites the sympathetic nervous system. When the sympathetic nerve becomes overly activated, our body tenses its muscles tightly, just as if entering a state of emergency. In particular, the trapezius muscle, sternocleidomastoid, and levator scapulae around the shoulders and neck are muscles that react very sensitively to stress. These muscles are essential for maintaining posture and moving the head. When this state of tension persists, blood circulation within the muscles is hindered, reducing the supply of oxygen and nutrients. When blood circulation worsens, fatigue substances such as lactic acid accumulate within muscle cells, which in turn stimulate nociceptors and induce pain. Furthermore, chronic muscle tension can form a trigger point, felt like a hard band inside the muscle fiber. This trigger point can cause severe pain when pressed or produce referred pain that radiates to other areas. The headaches that often spread to the back of the neck or head can correspond precisely to this. In addition, when the brain is exposed to chronic stress and pain, the pain threshold decreases, causing one to feel more severe pain even from minor stimuli. This can be explained by changes in neuroplasticity, where the brain's pain matrix reorganizes to respond hypersensitively. Inflammatory responses also play an important role. Continuous muscle tension and injury induce micro-inflammation, which promotes the secretion of pain substances such as substance P and calcitonin gene-related peptide, potentially creating a vicious cycle that further worsens pain. The practice we commonly call acupressure can help break the links of this vicious cycle. Stimulating specific acupoints goes beyond simply pressing muscles; it activates mechanoreceptors distributed under the skin and muscle, modulating the pathways that transmit pain signals to the brain. This can be explained by the gate control theory, and at the same time, it promotes the secretion of natural pain-inhibiting substances such as endorphins in the brain, bringing about pain relief. It also improves local blood flow and induces muscle relaxation, lowering sympathetic hyperactivity and enhancing parasympathetic nerve activity to aid overall bodily relaxation. Science is simply explaining the wisdom of the Donguibogam in a different language, ultimately showing that restoring our body's balance is the essential core.
