The head should not be hit anywhere. Because no matter where the head is hit, it may cause intracranial hemorrhage, or serious cranial injury. The more dangerous areas, especially the middle of the top of the head and the back of the head, as well as the temporal area on both sides, are the temples. The middle of the head is the location of the superior sagittal sinus, the largest intracranial venous sinus, through which about 1/3 of the blood flow passes, and if this area is damaged, it is likely to cause fatal intracranial hemorrhage. The same is true for the area at the back of the head, which contains the transverse sinus, also a very large intracranial venous sinus, which can also cause life-threatening bleeding in patients if it causes bleeding. In addition, the area of the temporal temples on both sides is the location of the middle dural artery, which is a relatively weak part of the skull and, if traumatized, could easily cause the middle cerebral artery to rupture and cause an acute epidural hematoma.
