Abstract
Abstract The specification discloses a device for inducing dive reflex, and the associated bradycardia and vasoconstriction in the human through the application of cold stimulus to the facial nerve, which communicates with the parasympathetic nervous system. The device comprises a pair of opposed temperature-controllable, face-engaging members and a tension member interconnecting and biasing the face-engaging members toward one another to secure the face-engaging members on the face over a portion of the area in which the facial nerve surfaces. A method of inducing dive reflex using the device is also disclosed.
