A concussion is a mild traumatic brain injury that usually occurs after a blow to the head or a sudden jolt that causes the brain to move within the skull. Most people who experience a concussion make a full recovery if they follow the correct rest and recuperation protocols, although the timeframe for recovery can vary between individuals. Understanding the early signs of a concussion and following a structured return to normal activities is essential for ensuring the brain heals effectively and to prevent further injury.

Immediate Care Following a Head Injury
The most important immediate treatment for a concussion is ensuring the person is safe, monitored by a responsible adult, and allowed to rest both physically and mentally. Following a bump or blow to the head, it is vital to stop any current activity, particularly sports or physical exercise, to prevent the risk of a second, more serious injury. If the person is conscious and stable, they should be taken home to recover in a quiet environment.
In the first 24 to 48 hours, monitoring is key. A responsible adult should stay with the person to check for any worsening symptoms. During this initial period, it is recommended to avoid alcohol and any medications that can cause drowsiness or increase bleeding risks, such as aspirin, unless specifically advised by a doctor. For pain relief, paracetamol is generally considered the safest option for managing a headache.
The Importance of Physical and Cognitive Rest
Recovery from a concussion relies heavily on resting the brain, which involves reducing both physical exertion and activities that require intense mental concentration. Physical rest means avoiding any strenuous exercise, heavy lifting, or sports until symptoms have significantly improved. Cognitive rest involves limiting “screen time” on phones, computers, and televisions, as well as avoiding demanding tasks like reading, studying, or complex problem-solving.
As symptoms begin to subside, a gradual reintroduction of light activity can begin. This is often referred to as a “graded return” to activity. If symptoms return or worsen during any stage of this process, it is a clear sign that the brain still needs more time to heal, and the person should return to a lower level of activity for at least 24 hours.
Monitoring for Emergency Red Flags
While most concussions are mild, it is essential to recognise specific symptoms that indicate a more severe brain injury requiring immediate hospital assessment. If a person loses consciousness, even briefly, at the time of the injury, they must be assessed by a medical professional.
| Symptom Category | Stable Concussion Signs | Emergency Red Flags (Call 999) |
| Consciousness | No loss of consciousness | Any period of unconsciousness |
| Vomiting | Mild nausea | Repeated or projectile vomiting |
| Vision/Speech | Slight headache | Slurred speech or double vision |
| Coordination | Feeling slightly dazed | Seizures, fits, or difficulty walking |
| Behaviour | Mild irritability | Confusion, aggression, or drowsiness |
Conclusion
The recommended treatment for a concussion focuses on immediate safety, diligent monitoring by an adult, and a period of physical and mental rest to allow the brain to recover. Recovery is a gradual process, and rushing back to work, school, or sport can prolong symptoms. Most individuals will see a significant improvement within a few days, but a cautious approach is always necessary. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
How long does it typically take to recover from a concussion?
Most people find their symptoms improve within a few days to two weeks, though some may take longer depending on the severity of the impact.
Can I go to sleep after hitting my head?
It is usually safe to sleep, but a responsible adult should be present to check on you periodically and ensure you can be easily woken up.
When is it safe to return to contact sports?
You should be entirely symptom-free at rest and during light exercise before considering a return to contact sports, often following a specific “return to play” protocol.
Should I stay in a dark room to recover?
While avoiding bright lights and loud noises can help if you are sensitive to them, total isolation in a dark room is no longer strictly recommended for the entire recovery period.
Is a CT scan always necessary for a concussion?
No, a CT scan is usually only performed if a doctor suspects a more serious injury, such as a skull fracture or a bleed on the brain.
Can I drive after a concussion?
You should not drive until you are no longer experiencing symptoms like dizziness, confusion, or blurred vision that could impair your ability to operate a vehicle safely
