If you are at home, you can treat minor head injuries by sitting quietly and using an icepack. You need someone with you to watch you closely for 24 hours (or 48 hours for children or older people). You can take paracetamol, but not other painkillers. There is no need to stay awake following a head injury.

Immediately after hitting your head, you should stop all activity and perform a self-assessment or have someone monitor you for signs of a concussion or serious trauma. Applying a cold compress or ice pack to any swelling can help reduce inflammation, and you should rest quietly for the first few hours. It is critical to watch for "red flag" symptoms such as loss of consciousness, persistent vomiting, slurred speech, sudden weakness, or a worsening headache; if these occur, you must seek emergency medical attention or call 911 (or 000) immediately. In 2026, medical protocols emphasize avoiding screens (phones, TVs) and high-concentration tasks for at least 24–48 hours to allow the brain to heal. You should also have someone stay with you for the first 24 hours to ensure your condition doesn't deteriorate while you sleep. Avoid alcohol and blood-thinning painkillers like aspirin unless advised by a doctor.
