How to reduce swelling from a head injury due to a car accident

Head injuries from car accidents can be alleviated through local pressure, cold compresses, or warm compresses. 1. Local pressure: After the head has been struck, it is recommended to apply manual pressure to the affected area. Applying localized compression can effectively slow the expansion of hematoma, reduce its size, and help reduce swelling. 2. Cold compress: Within the first 24 hours after a head bump, it is advisable to wrap an ice pack in a towel and apply it as a cold compress to the injured area to prevent the hematoma from enlarging. 3. Warm compress: If the hematoma remains significant more than 24 hours after the injury, applying a warm towel to the affected area may help promote absorption of the hematoma. However, care must be taken to avoid burns.
