Concussion treatment starts with 1-2 days of rest, then a gradual return to activity guided by your symptoms. Aerobic exercise kept below the level that triggers symptoms, vestibular therapy for dizziness, and targeted care for headaches, sleep, and vision problems are all backed by evidence. Complete bed rest for days is outdated and may slow recovery.
If you or someone you love has been diagnosed with a concussion, or if symptoms are dragging on, here is what the current evidence says about getting better.
What Is a Concussion?
A concussion is a mild traumatic brain injury (mTBI) caused by a bump, blow, or jolt to the head. It can also happen when a hit to the body causes the head to snap back and forth. That sudden movement can make the brain bounce or twist inside the skull, triggering chemical changes and sometimes damaging brain cells.
You do not have to lose consciousness to have a concussion. Many people never black out. Symptoms may appear right away or take hours to show up, and they usually fall into four groups:
- Physical: Headache, dizziness, nausea, sensitivity to light or noise, blurry vision, balance problems
- Cognitive: Feeling foggy, difficulty concentrating, memory problems, slowed thinking
- Emotional/behavioral: Irritability, sadness, anxiety, mood swings
- Sleep: Sleeping more than usual, trouble falling asleep, or waking frequently
Step 1: Rest — But Not Too Much
The first 24-48 hours after a concussion call for rest. That means:
- No physically demanding activities (sports, heavy labor, vigorous exercise)
- Less screen time and fewer mentally demanding tasks (reading, homework, complex work projects)
- Reducing loud noise and bright light if they trigger symptoms
The old advice to sit in a dark room until all symptoms disappear has been replaced. Studies show that prolonged complete rest may extend recovery rather than shorten it. The CDC now recommends easing back into regular activities after 1-2 days of rest, even if mild symptoms remain.
Find the activity level where your symptoms do not get worse. Stay there until you can comfortably do more.
Step 2: Gradual Return to Activity for Concussion Recovery
Once you have rested for a day or two, the goal is a slow, steady return to your normal life. This graduated approach was developed for athletes but applies to anyone recovering from a concussion.
The idea is simple: move through activity levels one at a time, waiting at least 24 hours at each level, and only advance when you have no symptom flare-up.
Stages:
- Light daily activity (short walks, reading for brief periods)
- Light aerobic exercise (slow jogging, swimming, stationary cycling with no resistance)
- Moderate activity (faster jogging, basic weight training)
- Heavy non-contact activity (sport-specific drills or full work demands)
- Return to full activity
If symptoms come back at any stage, drop back one level and wait until you feel better before trying again.
Why Aerobic Exercise Helps
This is where the science has changed most. Aerobic exercise kept below the heart rate level that triggers your symptoms (sometimes called "subthreshold" exercise) has been shown in multiple clinical trials to shorten recovery and improve blood flow to the brain. It is one of the strongest interventions backed by randomized controlled trial data.
Do not take this as a reason to push through pain. If exercise makes your symptoms worse, that is too much. The benefit comes from staying just under your personal threshold.
Step 3: Concussion Treatment for Specific Symptoms
Recovery depends on what is bothering you most. Different symptoms call for different approaches.
Headaches
Headache is the most common symptom after a concussion. For mild to moderate pain, your doctor may suggest acetaminophen (Tylenol) or ibuprofen (Advil). Take these only as directed by a healthcare provider.
One caution: taking headache medication too often (more than a few days a week) can cause rebound headaches. This makes the original problem harder to treat. If your headaches are frequent or severe, see a doctor rather than managing them on your own.
If your headaches feel like migraines (throbbing, with light sensitivity and nausea), your doctor may consider prescription migraine treatment. Post-traumatic migraine is a recognized complication of concussion.
Sleep Problems
Sleep problems after a concussion are common. Some people sleep far more than usual. Others cannot fall asleep or wake up through the night. Both can slow recovery.
Basic sleep hygiene helps: stick to a regular schedule, keep the room dark and quiet, avoid screens before bed. For persistent insomnia, cognitive behavioral therapy for insomnia (CBT-I) is well-supported by research and works without the risks that come with sleep medication.
Dizziness and Balance Problems
Vestibular therapy is the right tool for dizziness and balance issues. Vestibular physical therapists use specific exercises to retrain the inner ear and brain to work together. These include:
- Eye-head coordination drills
- Balance exercises on unstable surfaces
- Gaze stabilization exercises
Not all physical therapists offer this. Ask your doctor for a referral to someone with specific concussion or vestibular training.
Vision Problems
Convergence insufficiency (difficulty focusing on close objects) is common after a concussion. You might notice double vision, eyestrain, or trouble reading even short passages.
Vision therapy (also called neuro-optometric rehabilitation) uses guided exercises to retrain how your eyes move and focus together. Some people also benefit from prism lenses or tinted lenses that reduce visual discomfort.
Mood and Cognitive Symptoms
Irritability, anxiety, and depression can follow a concussion, especially when recovery takes longer than expected. Cognitive behavioral therapy (CBT) and other forms of psychotherapy have solid evidence behind them for post-concussion mood symptoms.
For cognitive difficulties like memory or concentration problems, a gradual return to mental demands works the same way as graduated physical activity. Talk to your employer or school about temporary accommodations if you need them.
Step 4: Know When to Get Help Fast
Emergency Warning Signs
Go to the emergency room right away if you or someone you are with has:
- One pupil noticeably larger than the other
- Extreme sleepiness or inability to be woken
- A headache that keeps getting worse
- Repeated vomiting
- Seizures
- Growing confusion or agitation
- Slurred speech
These can point to a serious brain injury that needs immediate care.
When to See a Concussion Specialist
If your symptoms have not improved much after 2-4 weeks, ask for a referral to a concussion specialist. Depending on your symptoms, that might be:
- A neurologist for ongoing headache or cognitive symptoms
- A sports medicine physician for return-to-activity clearance
- A neuropsychologist for cognitive and memory testing
- A vestibular physical therapist for dizziness or balance
- A neuro-optometrist for vision problems
Research consistently links earlier care with faster recovery. The longer you wait to see a specialist, the greater the risk of a prolonged recovery.
What About Post-Concussion Syndrome?
Most people recover within 7-10 days. Children and teenagers may take up to a month. But for some people, symptoms last longer, a condition often called post-concussion syndrome (PCS).
PCS does not mean permanent damage. Many people with persistent symptoms recover fully with the right treatment. Factors that may slow recovery include a history of multiple prior concussions, pre-existing anxiety or depression, older age, or a delay in getting care.
Programs that combine multiple therapies (physical therapy, vestibular therapy, vision therapy, cognitive strategies, and psychological support) show the best results for people with persistent post-concussion symptoms. If you are still struggling after a month, a thorough evaluation is the right next step.
Frequently Asked Questions About Concussion Treatment
How long does it take to recover from a concussion?
Most adults recover within 7-10 days. Children and teenagers typically take two to four weeks. Non-sport-related concussions can take up to three months. Age, prior concussion history, and how quickly you seek care all affect the timeline.
What should you avoid after a concussion?
In the first 24-48 hours, avoid strenuous physical activity, prolonged screen use, and tasks that worsen symptoms. Avoid alcohol. Do not return to contact sports or driving until a doctor clears you. Avoid staying completely inactive for days. Easing back into activity under guidance is better than rest alone.
Can exercise help a concussion heal faster?
Yes, when done at the right level. Aerobic exercise that stays below the heart rate that triggers your symptoms is backed by multiple clinical trials. It improves blood flow to the brain and shortens recovery time. The key factor is staying under your personal symptom threshold.
What is the best medicine for a concussion headache?
Acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) may help when taken as directed by a doctor. If headaches resemble migraines, prescription medications may be needed. Avoid using pain relievers more than a few days per week, as overuse can cause rebound headaches. Frequent or severe headaches deserve a doctor visit.
When should you go to the hospital for a concussion?
Seek emergency care right away if you notice: one pupil larger than the other, a headache that keeps worsening, repeated vomiting, seizures, extreme drowsiness, inability to recognize people or places, or slurred speech. These signs can point to a more serious brain injury.
What is post-concussion syndrome?
Post-concussion syndrome refers to symptoms that last longer than expected, generally beyond four weeks in adults. Common symptoms include ongoing headache, dizziness, trouble concentrating, and mood changes. It is treatable. Seeing a concussion specialist rather than waiting is the right approach.
Does sleep help a concussion heal?
Yes. The brain repairs itself during sleep, making quality rest one of the most important parts of recovery. Good sleep hygiene supports healing. Sleep deprivation can worsen symptoms and extend recovery. If you are struggling to sleep, talk to your doctor rather than pushing through it.
