Screen Time After a Concussion: How Much Is Too Much?
If you're recovering from a concussion and your phone, computer, or television makes you feel worse, you may be wondering:
How much screen time is too much after a concussion?
Maybe you've noticed that 20 minutes on your computer gives you a headache.
Or scrolling on your phone makes you dizzy.
Maybe reading emails makes your eyes feel strained.
Or you've gotten to the point where you can tolerate a little screen time, but after a few hours your brain feels completely exhausted.
If this sounds familiar, you're not alone.
Screen use can be challenging for some people after a concussion because it combines visual, cognitive, and sensory demands.
But that doesn't necessarily mean you need to avoid screens completely.
The better question is:
What amount of screen use can you currently tolerate, and how can you gradually build that tolerance?
Why Do Screens Make My Concussion Symptoms Worse?
Using a screen may seem like a simple activity, but your brain is doing a lot of work.
When you're looking at your phone or computer, you're:
Focusing your eyes
Moving your eyes across the screen
Processing words and images
Maintaining attention
Remembering information
Interpreting visual movement
Filtering out distractions
Processing light and contrast
After a concussion, some people have difficulty tolerating these demands.
The result may be:
Headache
Dizziness
Eye strain
Blurred or double vision
Nausea
Brain fog
Difficulty concentrating
Fatigue
Light sensitivity
Visual complaints are common after mild traumatic brain injury, and a 2026 review found that post-concussion visual symptoms frequently involve areas such as eye movement, focusing, convergence, and light sensitivity.

Can Looking at My Phone Cause Dizziness After a Concussion?
It can.
Your visual system and vestibular system work together to help your brain understand movement.
When you're scrolling through a phone, your eyes are seeing movement while your body is relatively still.
For some people after a concussion, that visual motion can be difficult for the brain to process.
You may notice:
Dizziness while scrolling
Nausea
A feeling that the screen is moving
Difficulty reading
Headaches
Eye strain
This can be particularly noticeable when you're scrolling quickly or watching videos with a lot of movement.

Why Does My Phone Give Me a Headache After a Concussion?
If your phone consistently triggers headaches, several things may be contributing.
You may be:
Focusing at a close distance for a long period
Moving your eyes rapidly
Exposing yourself to bright light
Reading small text
Scrolling continuously
Holding your neck in one position
Concentrating for longer than your current tolerance allows
The headache may therefore be the end result of several different demands, rather than the screen itself being the sole problem.
This is why simply turning down your brightness may not completely solve the problem.
Why Does My Computer Make Me Feel Like My Brain Is Shutting Down?
Computer work can be especially challenging after a concussion.
Unlike watching a television show, computer work often requires active concentration.
You may be:
Reading
Writing
Switching between programs
Answering emails
Attending video meetings
Looking back and forth between documents
Processing new information
This places significant demands on both your visual and cognitive systems.
If your current tolerance is lower than it was before your concussion, you may reach your limit much faster.
You might notice:
"I can work for 30 minutes, but after that I can't think clearly anymore."
That's useful information.
It tells you something about your current tolerance.
Should I Avoid Screens Completely After a Concussion?
Not necessarily.
There is evidence that reducing screen exposure during the very early phase after a concussion may be helpful. One randomized clinical trial found that participants who avoided screen time during the first 48 hours had a shorter median time to symptom resolution than those who were permitted unrestricted screen use.
But that doesn't mean that everyone with persistent concussion symptoms should spend weeks or months avoiding screens.
In fact, newer research suggests the relationship between screen time and recovery is more complicated than simply "more is bad."
A 2026 study of adolescents found that moderate screen use during the first few days after concussion was associated with faster symptom resolution than both very low and very high levels of use.
The goal is not necessarily zero screen time.
The goal is finding an amount of screen exposure that your current system can tolerate and gradually rebuilding that tolerance.
So How Much Screen Time Is Okay After a Concussion?
There isn't one number that is appropriate for everyone.
Your tolerance depends on factors such as:
How recently you were injured
Your current symptoms
Your visual tolerance
Your cognitive tolerance
Your sleep
Your headaches
Your dizziness
Your overall activity level
Someone who can comfortably tolerate two hours of computer work may be ready for a very different level of activity than someone who develops a headache after 15 minutes.
Your symptoms can help guide your starting point.
What If I Need to Work on a Computer?
This is one of the biggest challenges for adults recovering from concussion.
You may not have the option of simply eliminating screens.
You have a job.
You need to answer emails.
You may need to attend meetings.
You may have children, bills, or other responsibilities.
Instead of thinking:
"I can't use a computer."
Try thinking:
"How can I make computer use more tolerable while I rebuild my capacity?"
That might include:
Shorter work periods
Planned breaks
Reducing unnecessary multitasking
Adjusting screen brightness
Increasing text size
Reducing visual clutter
Changing your screen position
Alternating screen-based and non-screen activities
Gradually increasing your work tolerance
The appropriate modifications will depend on what is actually triggering your symptoms.
What Is the 20-20-20 Rule?
You may have heard of the 20-20-20 rule:
Every 20 minutes, look at something about 20 feet away for 20 seconds.
This can be a useful strategy for reducing prolonged near-focus demands and giving your eyes a break.
However, if you have persistent concussion-related visual symptoms, simply following the 20-20-20 rule may not address the underlying problem.
If you consistently develop dizziness, headaches, double vision, or significant visual discomfort, an appropriate evaluation may be warranted.
Why Does Reading Make My Concussion Symptoms Worse?
Reading requires both visual and cognitive processing.
Your eyes have to:
Focus
Converge
Track across the page
Move from one line to the next
At the same time, your brain has to understand and remember what you're reading.
If your visual system or cognitive system is struggling after a concussion, reading can become exhausting.
You may notice:
Losing your place
Words seeming to move
Difficulty concentrating
Headaches
Eye fatigue
Dizziness
Needing to reread the same paragraph
If this is happening, it's worth considering whether visual or oculomotor issues are contributing.
What If Screens Trigger Brain Fog?
Brain fog after a concussion may become particularly noticeable during screen use.
You may be able to look at your phone without much difficulty but struggle when you need to:
Read a long article
Write an email
Attend a Zoom meeting
Analyze a spreadsheet
Work on a complicated project
That's because these activities require significantly more cognitive processing.
If you're experiencing brain fog after screen use, you may need to gradually rebuild your cognitive tolerance rather than simply avoiding screens indefinitely.

What If Screen Time Triggers My Headaches?
If screen use consistently triggers headaches, pay attention to the pattern.
Ask yourself:
How long can I use a screen before symptoms begin?
Does reading cause more problems than watching television?
Does scrolling trigger symptoms more quickly than a stationary image?
Does brightness make things worse?
Does my neck position affect my headache?
Do symptoms improve when I take a break?
These details can help identify what aspect of screen use may be contributing.

How Can I Gradually Increase My Screen Tolerance?
Instead of going from very little screen time to several hours, consider gradually increasing your exposure.
For example, you might begin with an amount you can tolerate reasonably well.
Then, over time, gradually increase:
Duration
How long you can use a screen.
Complexity
How mentally demanding the activity is.
Visual demand
How much reading, scrolling, or visual processing is required.
Environment
How much additional sensory stimulation you're dealing with.
The goal is not to see how long you can tolerate symptoms.
The goal is to gradually build capacity.
What If I Get Symptoms Every Time I Use a Screen?
If even short periods of screen use consistently trigger significant symptoms, it may be worth having your symptoms evaluated rather than simply forcing yourself through them.
Persistent visual symptoms can involve several different mechanisms, and a 2026 review found that assessment of areas such as convergence, accommodation, and near-point of convergence can be relevant when evaluating post-concussion visual complaints.
Depending on your symptoms, a healthcare professional may consider visual, vestibular, cervical, cognitive, or other contributors.
Screen Time Is Only One Piece of the Concussion Puzzle
If screens trigger your symptoms, it's tempting to focus entirely on screen time.
But what if the screen is simply revealing another problem?
For example:
Screen use → headache
But perhaps the underlying contributors include:
Visual dysfunction + cognitive fatigue + neck position
Or:
Screen use → dizziness
But perhaps the underlying contributors include:
Visual motion sensitivity + vestibular dysfunction
Or:
Screen use → brain fog
But perhaps the underlying contributors include:
Cognitive overload + poor sleep + exercise intolerance
This is why looking at the bigger picture can be so important.

Frequently Asked Questions About Screen Time After Concussion
How much screen time is okay after a concussion?
There isn't one amount that works for everyone. Screen tolerance depends on the person's symptoms, stage of recovery, and ability to tolerate visual and cognitive demands.
Should I avoid my phone after a concussion?
Short-term reduction in screen exposure may be helpful early after a concussion, but complete avoidance for prolonged periods isn't necessarily appropriate. Research suggests the relationship between screen exposure and recovery is more nuanced than simply avoiding all screens.
Why does my phone make me dizzy after a concussion?
Scrolling and visual motion can place demands on the visual and vestibular systems. Some people with concussion have difficulty processing this information, which can contribute to dizziness or nausea.
Why does screen time give me a headache after a concussion?
Screen use can involve prolonged near-focus, visual processing, cognitive concentration, light exposure, and sustained neck positioning. One or several of these factors may contribute to headaches.
Can screen time make concussion symptoms worse?
Yes, screen use can temporarily aggravate symptoms in some people. However, symptom aggravation does not necessarily mean that the screen is causing additional brain injury.
How long should I avoid screens after a concussion?
Recommendations depend on the stage of recovery and the individual. Evidence supports reducing screen exposure in the very early period, while longer-term management generally focuses more on appropriate activity and gradual return to normal function.
Will I eventually be able to use screens normally again?
Many people improve their tolerance to normal activities during concussion recovery, but the timeline varies. If screen use continues to cause significant symptoms, an evaluation can help identify factors that may be contributing.
