Why shouldn't you hit the back of the head?
Generally, the reason why the back of the head should not be struck includes the high risk of intracranial hemorrhage, concussion, cerebral contusion and laceration, cervical spine fracture, and worsening of posterior fossa lesions. If any discomfort occurs, it is recommended to seek medical attention promptly and receive treatment under a doctor's guidance. Specific explanations are as follows:
1. Intracranial Hemorrhage
The bones at the back of the head are relatively fragile and close to critical brain structures. A blow to this area may cause local brain tissue bruising or tearing, leading to blood vessel rupture and resulting in subdural or subarachnoid hemorrhage.
2. Concussion
A concussion is a mild form of brain injury caused by a strong impact or jolt to the head, which causes the brain tissue to temporarily shift within the skull, resulting in transient disruption of brain function. Striking the back of the head may cause the brain to shake inside the skull, triggering a concussion.
3. Cerebral Contusion and Laceration
Blows to the back of the head may lead to organic brain damage, including contusions and lacerations, which can subsequently cause a series of complications such as brain edema and increased intracranial pressure.
4. Cervical Spine Fracture
When the back of the head is struck, the force may be transmitted to the cervical spine, potentially causing cervical fractures. This could result in permanent nerve damage and serious consequences such as paralysis.
5. Worsening of Posterior Fossa Lesions
The posterior cranial fossa houses the brainstem and cerebellum, which control vital functions such as breathing, heart rate, and balance. Blows to the back of the head may exacerbate existing injuries to the brainstem or cerebellum, leading to functional impairments.
In both daily life and sports activities, striking the back of the head is an extremely dangerous act and should be avoided as much as possible to prevent injury.
