AbstractRadiative cooling, a zero‐energy‐consumption passive cooling technology, enables spontaneous heat dissipation, reducing energy use and pollution, and provides an innovative solution for personal thermal management (PTM). This review thoroughly summarizes recent advances in radiative cooling fabrics, detailing the fundamental model of human body heat exchange and the essential cooling mechanism based on simultaneous high solar reflectivity and mid‐infrared (MIR) emissivity. Strategies for material spectral design, fabrication processes, and structural optimization techniques are systematically analyzed. Key performance metrics are analyzed alongside multifunctional integrations such as evaporative–radiative coupling and thermal‐moisture management. Emerging applications in adaptive thermoregulation and health monitoring are explored, highlighting the versatility of technology. Finally, current challenges are discussed, and future research directions are outlined to stimulate deeper investigation and accelerate the industrialization and widespread application of this sustainable technology.
