Devices configured to monitor biological parameters, and to provide treatment, at an Abreu brain thermal tunnel

A device configured to apply heat or cold to an Abreu brain thermal tunnel (ABTT) terminus, the device comprising:

• a support structure configured as eyeglass frames;
• and
• a resistive heater positioned on the support structure, the resistive heater being positioned to heat a portion of the support structure that extends along the superior palpebral vein when the support structure is worn by a user and the resistive heater being configured to provide thermal exchange with the superior palpebral vein when the support structure is worn by a user,
• wherein the resistive heater extends away from the ABTT terminus along an upper eyelid region and alongside the superior palpebral vein of the user when the structure is worn by the user on both a left side of the user and a right side of the user, the resistive heater terminating before reaching the end of the superior palpebral vein of the user on the left side of the user and terminating before reaching the end of the superior palpebral vein of the user on the right side of the user.
