A body surface temperature adjustment apparatus efficiently adjusts a surface temperature of a treatment target site of a patient. The apparatus includes a first tank that stores water, a water temperature adjustment unit that adjusts a temperature of the water to a predetermined temperature, a cooling apparatus that surrounds a scalp, a first pump that circulates the water, a controller that controls the water temperature adjustment unit and the first pump, and at least one water outlet for releasing the water circulated by the first pump toward the scalp surrounded by the cooling apparatus body, and a collection unit that collects the water released within a scalp surrounding space into the first tank.
