What To Do For Concussion?

If you or someone near you has a concussion, the first thing to do is stop all activity immediately. Then call a doctor or go to an emergency room for an evaluation — even if symptoms seem mild. Rest for the first 24 to 48 hours, both physically and mentally, and avoid any activity that makes symptoms worse. The most important step is getting a proper medical assessment because concussions can look different in different people, and symptoms can change over time.

What Exactly Is a Concussion?

A concussion is a mild traumatic brain injury. It happens when a blow to the head or a sudden jolt causes the brain to move inside the skull. This movement stretches and damages brain cells on a chemical level. It is not the same as a bruise or a cut. You do not need to lose consciousness to have a concussion.

The Centers for Disease Control and Prevention (CDC) estimates that millions of concussions happen each year in the US. Many go unreported because people do not realize they have one. Common causes include falls, car accidents, sports injuries, and even bumping your head on a low cabinet.

Symptoms can show up right away or hours later. Headache, dizziness, confusion, nausea, sensitivity to light or noise, and trouble concentrating are all common signs. Some people feel foggy or irritable. Others have trouble sleeping. No two concussions are exactly alike, which is why personalized care matters.

What To Do For Concussion in the First 48 Hours

The first two days after a concussion are the most critical for recovery. The brain needs rest to begin healing. Physical rest means no running, jumping, lifting, or any activity that raises your heart rate. Mental rest means no screens, no reading for long periods, no video games, and no intense thinking like work or schoolwork.

Sleep is essential. Do not wake someone with a concussion every hour unless a doctor specifically tells you to. That old advice is outdated. Current guidelines from the CDC and the American Academy of Neurology say that uninterrupted sleep helps the brain recover. Only wake the person if they have severe symptoms like vomiting, worsening headache, or confusion that does not improve.

Avoid pain relievers like ibuprofen or aspirin in the first 24 hours unless a doctor approves. These can increase the risk of bleeding in rare cases. Acetaminophen (Tylenol) is generally considered safer for headache relief during this window, but always check with a medical professional first.

When to Seek Emergency Care for a Concussion

Most concussions do not require a hospital stay. But some symptoms signal a more serious problem. Go to the emergency room immediately if any of these happen:

• Loss of consciousness lasting more than 30 seconds
• Repeated vomiting
• A headache that gets worse over time
• Slurred speech or weakness on one side of the body
• Seizures or convulsions
• Confusion that does not improve
• Unequal pupil size
• Clear fluid or blood coming from the nose or ears

These signs could indicate a brain bleed or more severe injury. Do not wait to see if they go away. Call 911 or have someone drive you to the ER. It is always better to overreact than to miss a serious condition.

What Does the Research Say About Rest and Activity After Concussion?

Research published in the journal JAMA Pediatrics has changed how doctors think about rest after concussion. For years, the standard advice was complete rest until all symptoms disappeared. But studies now show that prolonged rest beyond a few days can actually slow recovery.

The current evidence suggests a balanced approach. After 24 to 48 hours of full rest, gradual reintroduction of light activity is helpful — as long as it does not make symptoms worse. This means short walks, light reading, or brief screen time. The goal is to find a level of activity that does not spike symptoms.

A 2019 study from the University of British Columbia found that children and teens who started light aerobic activity within a week of their concussion recovered faster than those who stayed completely inactive. The same principle applies to adults. Complete rest for more than a week may lead to deconditioning, mood changes, and delayed recovery.

That said, everyone is different. Some people need more rest. Some can do more sooner. The key is listening to your body and working with a healthcare provider who understands concussion management.

What To Do For Concussion During Recovery: A Practical Guide

Recovery from a concussion is not a straight line. Symptoms can come and go. A headache might fade for a day and return. Fatigue might hit after a short walk. This is normal and does not mean you are getting worse overall.

Here is a practical breakdown of what to do during recovery:

Return to work or school should happen gradually. Start with half days or reduced hours. Take breaks often. If symptoms worsen, pull back. Most people recover fully within two to four weeks. But some take longer, especially if they have had previous concussions or other health conditions.

Common Misconceptions About Concussion Treatment

There is a lot of bad advice about concussions online. Some of it is outdated. Some of it is just wrong. Here are a few myths worth clearing up.

One common myth is that you should keep someone awake after a concussion. This came from the old idea that sleeping could hide worsening symptoms. As mentioned earlier, current guidelines say sleep is good for recovery. The key is checking on the person periodically for severe symptoms, not keeping them awake.

Another myth is that you need a CT scan or MRI for every concussion. Most concussions do not show up on these scans. They are only needed if there is suspicion of a skull fracture, brain bleed, or other structural injury. Doctors use clinical evaluation — asking questions, checking balance, testing memory — to diagnose a concussion in most cases.

Some people believe that a concussion only happens if you lose consciousness. That is false. Only about 10 percent of concussions involve loss of consciousness. Most people with a concussion are awake the whole time.

Finally, there is no such thing as “toughing it out” with a concussion. Pushing through symptoms can make recovery take longer and increase the risk of second impact syndrome — a rare but dangerous condition where a second blow before the first concussion heals causes rapid brain swelling. This is why returning to sports or intense activity too soon is dangerous.

What To Avoid During Concussion Recovery

Some things can slow down recovery or make symptoms worse. Avoiding these is just as important as doing the right things.

Alcohol and recreational drugs should be avoided entirely during recovery. They interfere with brain healing and can mask symptoms. Caffeine should be limited because it can worsen headaches and disrupt sleep. Nicotine also slows healing.

Do not drive until a doctor clears you. Reaction times and decision-making can be off after a concussion even if you feel fine. The same applies to operating heavy machinery or making important decisions at work.

Avoid screen time for long stretches. The blue light and rapid eye movements can trigger headaches and fatigue. If you must use a screen, take breaks every 20 minutes and dim the brightness.

Do not return to sports or exercise without medical clearance. The American Academy of Neurology recommends a stepwise return to activity. This means starting with light aerobic exercise, then sport-specific drills, then full practice, and finally competition. Each step should take at least 24 hours and not cause symptoms.
