The self-heating sheet 13 comprises a supersaturated solution for releasing heat during crystallization, a containing bag 131 for containing the supersaturated solution, and a trigger for driving the supersaturated solution to crystallize. The light absorption heating layer 11 is arranged on the outer layer of the sweater, can receive more visible light, converts the visible light into heat energy, and can play a role in heating through external force. The moisture absorption heating layer 12 is arranged in the inner layer of the sweater and can be better attached to the skin of a human body, so that heat is generated by utilizing the moisture emitted by the breathing of the skin of the human body. The self-heating sheet 13 utilizes the instability of the supersaturated solution, and the cooling crystallization process thereof generates heat. Wherein, the sleeve 2 and the collar 3 can also adopt the same design.

After the supersaturated solution is stimulated by the trigger, the metastable state of the supersaturated solution loses balance, and excessive solute is separated out, namely the cooling crystallization process. This process releases excess heat into a stable solid. At high temperatures, however, the solubility of the solute increases and the coagulated solute is re-dissolved. The triggering condition of the trigger is mainly the creation of seed crystals, which, once put in a supersaturated solution, rapidly crystallize with the release of heat.
