Head thermoregulatory apparatus

A thermoregulatory apparatus, comprising:

• a core body temperature sensor;
• a head thermoregulatory device including a fluid pad, an input port, and an output port, wherein the fluid pad is positioned to contact a forehead of a user;
• a fluid device configured to heat or cool a fluid, the fluid device including the fluid, an input port, and an output port;
• fluid hoses between the head thermoregulatory device and the fluid device;
• a fluid valve coupled to the fluid hoses;
• and
• control circuitry coupled to the fluid valve and to the core body temperature sensor, wherein the control circuitry is configured to activate the fluid valve based on a determination that an absolute difference between a subsequent core body temperature and a baseline core body temperature exceeds a threshold.

A method for thermoregulation of a core body temperature, comprising:

• maintaining a temperature of a fluid in a reservoir;
• receiving a signal indicating a baseline core body temperature;
• receiving a signal indicating a subsequent core body temperature;
• determining whether an absolute difference between the subsequent core body temperature and the baseline core body temperature exceeds a threshold;
• activating, responsive to determining that the absolute difference exceeds the threshold, a fluid valve to circulate the fluid between the reservoir and a fluid pad positioned to contact a forehead of a user;
• and
• deactivating the fluid value three (3) minutes after the activating of the fluid valve.
