Caring for someone with a concussion means balancing rest with gentle activity, watching for warning signs, and being patient through a recovery that typically takes two to four weeks. Most concussions heal well at home, but the first 48 hours require close attention, and the days that follow call for a gradual, structured return to normal life.
Why the Brain Needs Time to Heal
A concussion disrupts the brain’s normal energy balance. The initial impact triggers a massive release of potassium from brain cells, and restoring that chemical balance demands huge amounts of energy. At the same time, the brain’s ability to produce that energy is impaired because blood flow and the tiny power plants inside cells (mitochondria) may be damaged. The result is a temporary energy crisis: the brain needs more fuel than it can make. That mismatch is why even simple mental tasks like reading, scrolling a phone, or following a conversation can feel exhausting in the early days. Understanding this helps explain why recovery isn’t about toughing it out. The brain genuinely needs reduced demand while its energy systems come back online.
The First 48 Hours
The first two days after a concussion are the most important window for monitoring. During this time, your job is to keep the person comfortable, limit activities that worsen symptoms, and watch for any signs that the injury is more serious than a typical concussion.
Let the person rest when they feel they need it, but don’t confine them to a dark room all day. The old advice of lying in bed with the lights off for days has been replaced by a more balanced approach: limit screen time and mentally or physically demanding activities for the first one to two days, then begin easing back into normal routines. Keeping them socially connected matters too. Isolation can worsen mood and slow recovery.
It’s safe to let the person sleep. You do not need to wake them every hour overnight unless a doctor has specifically instructed you to. However, in the first night or two, check on them periodically to make sure their breathing looks normal and they’re rousable if you gently try to wake them.
Danger Signs That Need Emergency Care
Most concussions resolve without complications, but a small number involve bleeding or swelling inside the skull that requires immediate treatment. Call 911 or go to the emergency department if you notice any of the following:
- Seizures or convulsions (shaking or twitching)
- Inability to recognize familiar people or places
- Repeated vomiting
- Increasing confusion, agitation, or unusual behavior
- Difficulty waking up, or excessive drowsiness that keeps getting worse
- Slurred speech, weakness, numbness, or loss of coordination
- A headache that steadily worsens and won’t go away
- One pupil noticeably larger than the other, or double vision
For infants and toddlers, also watch for inconsolable crying or refusal to eat or nurse. These danger signs can appear hours after the initial injury, which is why close observation in the first 48 hours is so critical.
Managing Pain Safely
Headaches are one of the most common concussion symptoms, and the person you’re caring for will likely want relief. Acetaminophen (Tylenol) is generally considered the safest option. Avoid ibuprofen (Advil, Motrin) and aspirin, especially in the early days, because these medications can increase the risk of bleeding. Before giving any pain reliever, confirm with the person’s healthcare provider that it’s appropriate for their situation.
Food, Fluids, and Energy
Nausea and loss of appetite are common after a concussion, which makes eating three full meals feel overwhelming. Instead, offer small meals or snacks every two to three hours. Don’t let the person skip breakfast, since the brain’s energy demands are high even at rest during recovery. Good options include fruit, smoothies, trail mix with nuts and dried fruit, and other nutrient-dense foods that are easy to eat in small amounts.
Hydration matters just as much. Offer fluids throughout the day rather than waiting for the person to say they’re thirsty. Water is ideal, but if they resist plain water, adding a squeeze of lemon or lime can help. Smoothies, fruits, and vegetables with high water content all count toward fluid intake.
Screen Time and Mental Activity
For the first one to two days, keep screen use to a minimum. Phones, computers, and televisions all demand visual processing and attention, which taxes the recovering brain. After that initial rest period, screens can be reintroduced gradually. If scrolling or reading triggers a headache, worsens dizziness, or makes concentration harder, that’s a signal to take a break.
The same principle applies to any mentally demanding task. Homework, work emails, complex problem-solving, and even long conversations can be draining. Let the person set the pace. Short bursts of activity with breaks in between work better than pushing through for hours.
Sleep and Rest During Recovery
Sleep is one of the brain’s primary repair modes, so encourage a consistent sleep schedule. The person may sleep more than usual in the first few days, and that’s fine. Some people experience the opposite: difficulty falling or staying asleep. Reducing screen exposure in the evening, keeping the room cool and dark at night, and maintaining regular wake-up times can all help.
During the day, rest when needed, but avoid spending the entire day in bed. Light activity like short walks, gentle stretching, or quiet socializing helps maintain normal sleep-wake cycles and prevents the deconditioning and low mood that come with prolonged inactivity.
Returning to Physical Activity
Once everyday activities no longer trigger symptoms and a healthcare provider gives the green light, physical activity can resume through a step-by-step process. The international standard is a six-step return-to-play progression, where each step takes at least 24 hours. If symptoms return at any stage, the person drops back to the previous step and waits before trying again.
- Step 1: Back to regular daily activities like school or work without symptoms.
- Step 2: Light aerobic exercise only, such as 5 to 10 minutes of walking, light jogging, or a stationary bike. No weightlifting.
- Step 3: Moderate activity that adds head and body movement, like moderate jogging or lighter-than-usual weightlifting.
- Step 4: Heavy non-contact activity, including sprinting, high-intensity biking, and full weightlifting routines.
- Step 5: Return to practice with full contact, if the sport involves it.
- Step 6: Return to competition.
Watch the person carefully after each day’s activity. New or worsening headaches, dizziness, or difficulty concentrating are signals to slow down.
Protecting Against a Second Injury
The single most important thing you can do as a caregiver is prevent a second concussion before the first one has healed. Second impact syndrome is rare but extremely dangerous. When an already-injured brain takes another hit, it can lose the ability to regulate blood flow, leading to rapid, severe swelling. The effects can become life-threatening within minutes. This means no contact sports, no roughhousing, and no activities with a fall risk until a medical professional has cleared the person for return.
Caring for a Child With a Concussion
Children and adolescents follow the same general recovery principles as adults, but school adds a layer of complexity. About 70% to 80% of concussed kids see their symptoms resolve within two to four weeks. During that time, returning to a full school schedule too quickly can backfire. A child who struggles to keep up may lose confidence, which compounds the stress of recovery.
Talk to the school about temporary accommodations: shortened days, extended deadlines, reduced homework loads, or breaks during the day when symptoms flare. After one to two days of initial rest, a gradual return to schoolwork is better than an all-or-nothing approach. Most concussed children should follow up with their pediatrician within one to two weeks to confirm symptoms are improving and to adjust the return-to-school and return-to-activity plan as needed.
For school-affiliated sports, many states require written clearance from a licensed medical professional before a child can return to play. Don’t rely on your child’s self-report alone. Kids and teens often downplay symptoms because they want to get back to their team.
What Recovery Looks Like Day by Day
Recovery isn’t a straight line. Some days will feel noticeably better, and others will feel like a step backward, especially if the person overdid it the day before. This is normal. The general pattern looks something like this: the first two days involve the most rest and the least activity. By the end of the first week, most people can handle light daily tasks without major symptom flares. By weeks two through four, the majority of people are close to or fully back to their normal routine.
If symptoms persist beyond four weeks, the condition may be classified as post-concussion syndrome, and a referral to a concussion specialist is worth pursuing. Lingering headaches, brain fog, sleep disruption, or mood changes that aren’t improving on their own can often be addressed with targeted rehabilitation.
