If you have a concussion, the most important first step is figuring out whether you need emergency care or can recover safely at home. Most concussions don’t require a hospital stay, but they do require a short period of reduced activity followed by a gradual return to your normal routine over days to weeks. The old advice to lie in a dark room until you feel better has been replaced by a more active approach that actually speeds healing.
Know When to Go to the ER
Some symptoms after a head injury signal something more serious than a typical concussion, like bleeding in or around the brain. Call 911 or get to an emergency department if you notice any of the following:
- Seizures or convulsions
- One pupil larger than the other, or double vision
- Repeated vomiting
- Slurred speech, weakness, numbness, or loss of coordination
- A headache that keeps getting worse and won’t go away
- Increasing confusion, agitation, or inability to recognize people or places
- Loss of consciousness, extreme drowsiness, or inability to stay awake
These danger signs can appear within minutes or develop over the first hours after an injury. If you’re watching someone else who hit their head, check on them periodically during the first 24 hours. Any of these warning signs means it’s time for an ER visit, not a wait-and-see approach.
The First 48 Hours: Relative Rest, Not Total Rest
For decades, the standard advice was to shut yourself in a dark, quiet room until all symptoms disappeared. That guidance is outdated. The 2022 International Concussion in Sport Consensus Statement is clear that strict rest, sometimes called “cocooning,” does not help recovery and may actually make things worse by increasing anxiety, deconditioning, and prolonging symptoms.
What works instead is relative rest. During the first one to two days, you should reduce screen time and avoid activities that are mentally or physically demanding. That means skipping video games, limiting texting and computer use, and putting off any work or school tasks that require heavy concentration. But you can still move around the house, have conversations, and go for short walks. Staying socially connected matters, too. Don’t isolate yourself.
Light physical activity like walking is safe and even encouraged within the first 24 to 48 hours, as long as it doesn’t significantly worsen your symptoms. Mild, brief symptom flare-ups during gentle movement (lasting under an hour) are normal and don’t delay healing. If symptoms get noticeably worse during an activity, ease off and try again the next day.
Managing Headaches and Sleep
Headaches are the most common concussion symptom, and they can stick around for days or weeks. Acetaminophen (Tylenol) is generally the recommended first choice for pain relief after a concussion. Some providers are cautious about anti-inflammatory pain relievers like ibuprofen in the very early hours because of a theoretical bleeding risk, so check with your doctor before switching medications.
Sleep is one of the best things for a recovering brain, and you should let yourself rest when you feel tired. There’s a persistent myth that you need to wake someone up every two hours after a concussion to make sure they’re okay. In reality, sleep helps recovery. If someone has already been evaluated and cleared to go home, what matters is watching for those danger signs listed above, not disrupting their sleep on a rigid schedule. If you’re unsure, your doctor can give you specific guidance for the first night.
Returning to Work or School
You don’t need to wait until you’re 100% symptom-free before going back to your normal routine. The goal is a gradual return, adding a little more each day as long as symptoms stay manageable. For students, this often means temporary adjustments at school:
- Reduced homework, focusing only on key assignments
- Extra time on tests, limited to one test per day
- Rest breaks throughout the day
- A quiet space for studying or lunch if noise is bothersome
- Permission to wear sunglasses or sit away from bright windows
- Extra time between classes to avoid crowded hallways
For adults at work, the same principles apply. Shorten your day if needed, take frequent breaks, and reduce tasks that require intense focus or screen time. Most people can start phasing back into their regular schedule within a few days, adding more as they tolerate it.
Getting Back to Exercise and Sports
Starting light aerobic exercise early, within two to ten days of injury, has been shown to reduce the chance of symptoms dragging on beyond a month. This doesn’t mean jumping back into competition. It means riding a stationary bike or going for a light jog at an intensity that doesn’t significantly spike your symptoms.
For athletes, return to sport follows a structured six-step progression, with each step taking at least 24 hours before moving on:
- Step 1: Return to regular daily activities (school, work) with medical clearance
- Step 2: Light aerobic activity only, like 5 to 10 minutes on a stationary bike or easy walking. No weightlifting.
- Step 3: Moderate activity with more head and body movement, like jogging and light weights
- Step 4: Heavy non-contact activity, including sprinting and full weightlifting routines
- Step 5: Full-contact practice in a controlled setting
- Step 6: Return to competition
The key rule: if new symptoms appear or old symptoms return at any step, stop and go back to the previous level. This isn’t optional caution. Returning to contact sports too quickly puts you at risk for a second concussion while your brain is still vulnerable, which can cause far more serious damage.
How Long Recovery Takes
Most adults recover from a concussion within two to four weeks. Children and teenagers often take longer. A study from Children’s Hospital Los Angeles found that the median time to full clearance for young patients (ages 6 to 20) was 65 days overall. Sports-related concussions resolved faster, with a median of 54 days, while non-sports concussions took a median of 91 days. In that same study, females took roughly twice as long to recover as males (91 days versus 45 days), and younger patients tended to recover more slowly than older ones.
These numbers can feel discouraging, but they represent full medical clearance, not the point where symptoms become manageable. Many people feel significantly better well before they’re officially cleared for all activities.
When Symptoms Last Longer Than Expected
If your symptoms persist beyond three months, the condition is called persistent post-concussive symptoms, sometimes referred to as post-concussion syndrome. Symptoms typically appear within the first 7 to 10 days after injury but can linger well beyond the expected recovery window. Common lingering problems include headaches, difficulty concentrating, dizziness, irritability, and sleep disruption.
Persistent symptoms don’t mean your brain is permanently damaged. They often involve a mix of factors: physical changes from the injury, disrupted sleep patterns, reduced physical fitness from inactivity, and sometimes anxiety or mood changes that developed during recovery. Treatment at this stage is usually tailored to whichever symptoms are most disruptive. Prescribed aerobic exercise that stays below the threshold where symptoms flare has been shown to be effective for people whose symptoms last longer than a month, helping the brain recalibrate its response to physical effort. A healthcare provider experienced with concussions can help identify what’s driving your specific symptoms and build a plan around that.
