Can applying hot or cold compresses treat a head injury from a fall?

Generally speaking, cold and hot compresses can assist in the treatment of head injuries to some extent, but their specific effectiveness depends on the severity of the injury and individual differences. The detailed analysis is as follows:

Cold compresses can cause local blood vessels to constrict, reducing the exudation of blood and tissue fluid, thereby effectively alleviating swelling. Hot compresses can promote local blood circulation, accelerating the absorption of bruising and exudated fluid, thus aiding in the reduction of swelling. However, cold compresses only provide temporary relief from swelling and pain and cannot replace professional medical treatment for severe head injuries, such as those accompanied by intracranial hemorrhage or fractures. Similarly, hot compresses can only serve as an adjunctive therapy and cannot directly heal severe head injuries.

If serious symptoms such as dizziness, nausea, vomiting, or impaired consciousness occur after a head injury, immediate medical attention should be sought rather than relying solely on cold or hot compresses. Following a head injury, in addition to applying cold or hot compresses, topical medications such as safflower oil or swelling and pain-relieving tinctures may be used under a doctor's guidance, along with oral or intravenous medications for additional treatment.

During the recovery period after the injury, adequate rest is essential to avoid excessive fatigue, and individuals should monitor their symptoms closely, seeking medical help promptly if any discomfort arises.
