Psychological Stress Linked to Eczema Among 16.5 Million Americans

Buzzline

Recent research indicates that psychological stress is a significant factor contributing to eczema outbreaks. Atopic dermatitis impacts around 16.5 million adults in the U.S. and approximately 101 million worldwide. In the study, 51 individuals were involved, revealing a distinct neural pathway: stress triggers a group of sympathetic neurons in the skin, leading to the release of a chemokine known as CCL11, which attracts eosinophils and intensifies inflammation. Mice under high stress exhibited four times the amount of eosinophils in skin samples compared to those not under stress. Researchers assert that stress is inherently integrated into the immune response of the skin.

00:00Stress does not just make eczema feel worse.

00:02Scientists say stress is a direct cause of flare-ups.

00:06Atopic dermatitis affects approximately 16.5 million adults in the United States.

00:12Globally, the figure is around 101.27 million adults or more.

00:18Researchers at Fudan University in Shanghai set out to find the biological route.

00:23They recruited 51 participants with atopic dermatitis diagnoses.

00:28They also ran mouse model experiments.

00:31Psychological stress activates a distinct subset of skin-innervating sympathetic neurons.

00:36Those neurons release a chemokine called CCL11.

00:40CCL11 recruits eosinophils, a type of white blood cell, into the skin.

00:45Elevated eosinophils cause inflammation and flare-ups.

00:48In the mouse experiments, stress-exposed animals had four times as many eosinophils in skin samples compared with non-stressed

00:56animals.

00:56And the process required repeated stress challenges over time.

01:00Study co-author Dr. Shenbin Liu says the most remarkable finding is that psychological stress communicates with the skin through

01:08a specific highway.

01:10Stress, he says, is not just a trigger.

01:12It is biologically wired into the skin's immune response.

01:16The study was published in the journal Science.

01:19Experts suggest practical steps alongside treatment.

01:23Regular emollient creams and barrier repair.

01:26Stress management through mindfulness and better sleep.

01:29Early intervention at the first sign of a flare.

01:32And breaking the itch-scratch cycle.
