Head relaxing pillow

It is an objective of the present invention to provide a head relaxing pillow. The pillow is made of an elastic material and includes a supporting main body, two contact portions, and a pressing portion. The top of the supporting main body is designed to support the neck of a user who lies face up. The bottom of the supporting main body is concavely provided with a recess. The supporting main body is provided with two sunken portions which are adjacent to two corresponding ends of the supporting main body respectively. Each contact portion has one end connected to one of the two corresponding ends of the supporting main body. The other end of each contact portion extends far from the supporting main body. The pressing portion extends from one side of the supporting main body and is located between the contact portions. When the user is lying, face up, such that his neck is resting on the supporting main body, the user's temporal bones correspond in position to the sunken portions respectively. Meanwhile, the supporting main body is deformed toward the recess due to the weight of the user's neck, such that the other ends of the contact portions may support the support the parietal bones of the user and the pressing portion may press against the occipital bone of the head of the user. Thus, the gaps in the user's skull are allowed to open slightly to lower the pressure of the cerebrospinal fluid in the skull and thereby enhance circulation of the cerebrospinal fluid.
