If you or someone in your household has a concussion, the first few days of recovery happen at home. The good news: most concussions resolve on their own with the right balance of rest, gradual activity, and watchful monitoring. But knowing exactly what to do (and what to avoid) makes a real difference in how quickly and safely the brain heals.
Know the Warning Signs First
Before settling into home care, you need to be confident the injury doesn’t require emergency treatment. Most concussions are mild, but some head injuries worsen in the hours after the initial blow. Call 911 or go to the emergency room if you notice any of these:
- Seizures or convulsions
- Repeated vomiting
- One pupil larger than the other, or double vision
- 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
For infants and toddlers, the same red flags apply, plus inconsolable crying and refusal to nurse or eat. These danger signs can appear hours after the injury, so keep checking throughout the first 24 to 48 hours.
Rest, but Not Too Much
The old advice was to lie in a dark room for days. Current guidelines are more nuanced. Rest is important during the first one to two days, when symptoms tend to be the most intense. You may need a short break from work or school, but usually no more than a day or two.
After that initial window, start easing back into your normal routine, even if mild symptoms linger. Light activities like reading, taking a short walk, or having a quiet conversation are fine. The key rule: if a particular activity makes your symptoms noticeably worse, scale it back. This approach, sometimes called “active recovery,” helps the brain re-engage without overwhelming it. Prolonged total rest beyond the first couple of days can actually slow recovery by deconditioniong the body and increasing anxiety about returning to normal life.
Managing Screen Time
Phones, tablets, TVs, and computers can aggravate headaches, eye strain, and light sensitivity after a concussion. Rather than cutting screens out entirely, start with about five minutes of screen time and gradually increase as long as your symptoms don’t flare up. Dimming brightness, using dark mode, and keeping sessions short all help.
If you need to use a computer for work or school, take frequent breaks. A good rhythm is a few minutes on, then a few minutes of rest with your eyes closed or focused on something distant. Over the first week, most people find they can tolerate longer and longer stretches.
Sleep and Overnight Monitoring
You may have heard you should never let a concussed person fall asleep, or that someone needs to wake them every hour through the night. Current CDC guidance says otherwise: let the person sleep normally and keep a regular bedtime routine. Sleep is when the brain does critical repair work, and disrupting it doesn’t help recovery.
That said, during the first night after injury, it’s reasonable to check on the person once or twice to make sure they’re breathing normally and can be briefly roused. You’re not looking for them to carry on a conversation, just confirming they respond when gently nudged. After the first night, normal sleep is the goal. Many people with concussions feel more tired than usual, and extra sleep in the first few days is perfectly fine.
Pain Relief: What’s Safe and What’s Not
Headaches are one of the most common concussion symptoms, and they can be persistent. Acetaminophen (Tylenol) is the recommended option for managing pain after a head injury. Avoid ibuprofen (Advil, Motrin) and aspirin, because these medications can increase the risk of bleeding, which is especially concerning when the brain may have sustained small blood vessel damage.
If acetaminophen isn’t controlling your headache, or if the headache steadily worsens over the first day or two, that’s worth a call to your doctor. A headache that keeps escalating is one of the danger signs that warrants medical evaluation.
Eating and Staying Hydrated
A recovering brain needs extra energy. You may not feel especially hungry, particularly if you’re dealing with nausea, but skipping meals slows healing. Small, frequent meals every two to three hours work better than trying to get through three large ones. Don’t skip breakfast.
Good recovery snacks include fruit, smoothies, trail mix with nuts and dried fruit, and dark chocolate. These provide a steady supply of the sugars, fats, and micronutrients the brain uses for repair. Hydration matters too. Offer fluids throughout the day rather than waiting until you feel thirsty. If plain water doesn’t appeal to you, add lemon or lime, or get fluids through smoothies, fruits, and vegetables. There’s no magic number of ounces to hit, but consistent sipping throughout the day is the goal.
Returning to Physical Activity
One of the biggest mistakes people make is jumping back into exercise or sports too soon. After a concussion, the brain enters a vulnerable metabolic state while it heals. Sustaining a second head injury before full recovery, even a seemingly minor one, can cause rapid and dangerous brain swelling. This condition is rare but potentially fatal.
The safe approach is a gradual, step-by-step return. After the first one to two days of rest, light aerobic activity like walking is fine as long as it doesn’t worsen your symptoms. From there, you can slowly increase intensity over the following days and weeks. Research from the University at Buffalo has shown that personalized aerobic exercise that stays below the level that triggers symptoms can actually speed concussion recovery.
A practical progression looks like this:
- Days 1–2: Rest, light household activities, short walks
- Days 3–7: Light aerobic exercise like brisk walking or stationary cycling, keeping intensity low enough that symptoms don’t increase
- Week 2+: Gradually add sport-specific drills, resistance training, and more demanding cognitive tasks
If symptoms flare at any stage, drop back to the previous level for another day or two before trying again. For athletes, a full return to contact sports should only happen after you’re completely symptom-free and cleared by a healthcare provider.
Mental and Emotional Symptoms
Concussion recovery isn’t just about headaches and dizziness. Many people experience irritability, difficulty concentrating, feeling “foggy,” anxiety, or sadness in the days and weeks after injury. These are normal parts of the healing process, not signs that something has gone permanently wrong.
Give yourself permission to do less. Break cognitive tasks into smaller chunks. If you’re returning to work or school, a reduced schedule for the first week can prevent symptom flare-ups. Let the people around you know what you’re dealing with so they can adjust expectations. Most cognitive and emotional symptoms resolve within two to four weeks, though a small percentage of people experience symptoms that last longer.
What Recovery Looks Like Day by Day
The first 24 to 48 hours are typically the worst. Headaches, nausea, sensitivity to light and noise, and fatigue tend to peak during this window. By the end of the first week, most people notice gradual improvement, though symptoms often come and go rather than disappearing in a straight line. You might feel great in the morning and worse by afternoon, or have a good day followed by a rough one. This is normal.
Most concussions resolve within 10 to 14 days in adults and up to four weeks in children. If your symptoms haven’t improved at all after two weeks, or if they’re getting worse rather than better, it’s worth following up with a healthcare provider who has experience managing concussions. Persistent symptoms don’t mean permanent damage, but they may benefit from targeted treatment like vestibular therapy, vision rehabilitation, or a structured exercise program.
