When the Body Heals: Recovery From Relational Stress

When the Body Heals: Recovery From Relational Stress

Recently, I came across stories of two young people who experienced serious autoimmune disorders after suffering for years under an abusive, narcissistic parent. A young woman, who had been on crutches and even in a wheelchair for five years, saw her physical disability vanish within weeks after a court removed her abusive father’s visitation rights. Similarly, a young man had endured a many years long autoimmune illness that left him disabled. Within three months of his narcissistic father’s death, he recovered. Six months after his father’s passing, he is now employed full-time. These are striking examples, but they are not uncommon. In fact, similar stories exist, well documented in the literature, involving three key research areas: psychoneuroimmunology, the study of adverse childhood experiences (ACEs), and the growing body of clinical work on narcissistic abuse as a chronic traumatic stressor. The Body Keeps the Score: Somatic Responses to Relational Threat The psychiatrist and trauma researcher Bessel van der Kolk explained that unresolved threats, especially interpersonal threats from which escape is impossible, are stored not only in …

New sunlight-powered nanospray heals infected diabetic wounds

New sunlight-powered nanospray heals infected diabetic wounds

Chronic infected wounds can take over daily life, especially for people living with diabetes. These wounds often refuse to heal, cause constant pain, and invite dangerous infections that resist antibiotics. Doctors struggle to treat them, and patients can feel trapped in a cycle of care that never seems to end. New research now points to a surprising helper in this fight: ordinary sunlight. A team of scientists has developed a nanospray that uses natural light to kill bacteria, stop bleeding, ease pain, and speed healing, all at once. The work focuses on diabetic foot ulcers, one of the most serious and common chronic wounds. The findings suggest a future where treating infected wounds becomes simpler, less painful, and far more accessible. The study describes a new material called SPS, short for sunlight powered spray. It is made from tiny self assembled particles that combine a near infrared light sensitive compound with chitosan oligosaccharides, a substance derived from natural sugars. When sunlight hits the spray, it activates a powerful response that targets infection and supports healing, …

Restoring cellular energy transfer heals nerve damage in mice

Restoring cellular energy transfer heals nerve damage in mice

A new study suggests that the sensory neurons responsible for pain rely on a designated delivery service to receive their energy. Researchers have discovered that support cells surrounding these neurons physically transfer mitochondria—the power plants of the cell—through tiny, tube-like bridges. When this supply chain breaks down, it appears to contribute to the nerve damage and pain associated with chemotherapy and diabetes. The study was published in the journal Nature. Our bodies possess an intricate network of sensory neurons that transmit information about touch, temperature, and pain to the central nervous system. These cells face a distinct logistical challenge. Their primary bodies are clustered in bundles called dorsal root ganglia located near the spine, but their thread-like extensions, called axons, must reach all the way to the toes and fingertips. Maintaining energy levels across such vast distances is energetically expensive. Biologists have historically understood that mitochondria are generated within a cell and remain there to produce energy. However, the extreme length of sensory axons raises questions about how neurons maintain enough power to function and …
