In a hot environment, personal cooling is important to maintain thermal comfort. In recent years, radiative cooling textiles can enhance the heat dissipation of the human body through the design of the infrared optical properties without consuming energy, which provides a new opportunity for realizing personal cooling in indoor and outdoor environments. Unlike the indoor controllable thermal environment, the outdoor thermal environment is characterized by strong solar irradiance intensity. Therefore, it is necessary to prevent the input of solar heat while enhancing human body heat dissipation. Based on the difference between indoor and outdoor thermal environments, we introduce the design strategy of radiative cooling textiles from the perspective of indoor and outdoor application scenarios, summarize the recent progress of radiative cooling textiles, and prospect the future development.
