Stress Cause Itchy Skin

Can stress cause itchy skin? Yes, according to a McMaster University researcher.

A study by a neuroimmunologist Petra Arck found that chronic stress mobilizes disease-fighting cells in the skin.

However, too much stress can cause these immune cells to over-react, and they inflame and irritate your skin instead of protecting it.

Stress exacerbates skin diseases by increasing the number of immune cells in the skin.

Arck, whose research was done along with the University of Medicine Berlin, said the process show up particularly in people with psoriasis or atopic dermatitis.

This isn’t the result of a short burst of stress. It’s more of a buildup.

“It’s definitely chronic stress, and chronic stress to me is the accumulation of many acute (short-term) stressors. The daily hassles, basically: My neighbor upsets me, the household is too much. That kind,” she said.

The study appears in The American Journal of Pathology.
