How does modern medicine explain these painful, chilled signals from a mother’s body? You might be surprised to learn that the wisdom of Donguibogam is far from unfounded. After delivery, a woman’s body goes through a veritable ‘hormone storm.’ Estrogen and progesterone levels, which stayed elevated throughout pregnancy, drop precipitously right after childbirth, disrupting all bodily systems. In particular, this heavily impacts the autonomic nervous system, which regulates functions vital to life, such as thermoregulation, blood circulation, and heartbeat. When hormonal shifts disrupt autonomic nervous system balance, the sympathetic nerve becomes excessively active, causing blood vessels to constrict; this diminishes blood flow volume to the hands, feet, and joints, generating a cold sensation. Much like crouching when a cold wind blows, this can be understood as part of the body’s own defense mechanism to avoid losing heat.
Furthermore, the hormone relaxin, secreted during pregnancy to loosen ligaments and connective tissue around joints to facilitate delivery, can linger in its effects for some time after childbirth. This leaves joints unstable, triggering micro-inflammatory reactions that make one more vulnerable to pain. On top of this, repetitive postures and excessive strains while holding and caring for a baby place stress on specific joints, readily causing joint pain. Major joints like the wrists, knees, and lower back endure continuous stress during childcare.
A cold sensation in the body goes beyond mere discomfort; it can be seen as the systemic consequence of autonomic nervous system imbalance. When thermoregulation weakens, one becomes sensitive even to minute temperature shifts, which can lead to anxiety and sleep disorder, setting off a vicious cycle that lowers the pain threshold. Furthermore, postpartum deficiencies in essential nutrients such as iron, calcium, and vitamin D directly affect bone and muscle health, exacerbating pain and cold sensations. Adequate nutritional support is vital for recovery. Psychological stress and postpartum depression are also significant factors that amplify physical symptoms, as stress hormones promote inflammatory responses and heighten sensitivity to pain.
Ultimately, what Donguibogam describes as ‘uterine cold’ can be understood in modern medicine as a generalized pain and cold sensation syndrome arising from a combination of autonomic nervous system hypofunction due to hormonal imbalance, joint laxity and inflammation, nutritional deficiencies, and psychological factors. Chills after childbirth are never something to take lightly. We must tenderly look after the signals our bodies are sending.
