Q I'm an office worker in my 40s. Even when I haven't touched anything, blisters come up on my hands whenever I'm stressed or the seasons change. Don't they only appear when something gets on my hands?
A Dyshidrotic eczema arises not only from external irritation but also from internal factors such as sweating, stress, seasonal change, and immune hypersensitivity. Because it is a multifactorial eczema with no single proven cause, it can recur whenever your condition declines, even without any memory of contact. That is why avoidance alone has limits, and managing your overall bodily state is also needed.
Detailed Answer
The cause of dyshidrotic eczema cannot be pinned to a single factor. Contact irritants such as metal (nickel) and detergents, sweat secretion, mental stress, changes in temperature and humidity at the turn of the season, and allergic predispositions such as atopy all act in combination. So it is common for symptoms to return when stress builds up or the season changes, even without directly touching anything.
Korean Medicine Clinic Perspective
At Dongjedang, we view this pattern of flaring even without external irritation as a signal of overload of the immune and autonomic nervous systems. The idea is that accumulated fatigue and stress disturb the autonomic nervous system, and subtle inflammation within the body is pushed out toward the tips of the hands and feet. So rather than only weighing what to avoid, we focus on settling the over-reactive body itself so that it is less shaken under the same circumstances.
