Description
The expansion of 5G millimeter waves (MMW) has raised concerns about their potential health effects on the human body. While previous studies have focused on biological effects, limited research has examined MMW-induced inflammation in living skin. This study aimed to determine whether 26.5 GHz quasi-MMW (qMMW) exposure induces inflammatory protein expression in rat dorsal skin. The dorsal skin of anesthetized rats was exposed to 0–1020 W/m² qMMW for 18 minutes, and Iba1 expression was analyzed using immunohistochemistry. Results showed that Iba1 expression increased with higher exposure intensity, particularly at 1020 W/m². These findings suggest that localized qMMW exposure may induce macrophage activation and an inflammatory response in the skin.
