Zusammenfassung: | A head cooler improves sleep quality without overcooling the head of a sleeping person. A head cooler (1) includes a main body (3), a pillow (7), and a connector (5). The main body (3) sends out a liquid for circulation between the main body (3) and the pillow (7) through the connector (5). The main body (3) includes a temperature adjuster (31) that adjusts a temperature of the liquid, a pump (32) that sends out the liquid toward the pillow (7), and a controller (35) that controls the temperature adjuster (31) and the pump (32) to adjust a temperature of the pillow at a first target temperature of 22 to 24 °C until an elapsed time from start of cooling reaches a target time of 200 to 250 minutes. |
