Abstract Self‐hygroscopic hydrogels, characterized by high evaporation enthalpy, cooling efficiency, and self‐regulating properties, have garnered significant attention. However, most current research focuses on enhancing the hygroscopic desorption performance, often overlooking importance of monitoring self‐regulation process, which limits its further application. Advanced visualization technologies, such as in situ electrical impedance tomography, low‐field nuclear magnetic resonance, hyperspectral imaging, offer potential insights into this behavior, yet they require additional devices, incur costs, involve complex sample preparation processes. Therefore, drawing inspiration from nature, humidity‐color‐sensitive hydrogels (HCSHs) strategy is proposed for visualized cooling. Benefiting strong polar responsiveness aggregation‐induced emission (AIE) molecules, hydrogel's fluorescence significantly changes with varying interior water content, thereby process monitored easily. Further, obtained hydrogel could be applied electronic device owing to polymer skeletons’ swelling ratio, adhesion, excellent self‐hygroscopic properties. This overcomes limitations visual technology materials provides new intelligent thermal management devices.
