Why Does Screen Time Make Post-Concussion Symptoms Worse?
Screens have become a part of most people’s daily lives, whether they’re watching TV to unwind after a long day or staring at computer screens at work. However, if you’re dealing with post-concussion symptoms following an accident, you may wonder whether looking at screens is helping or hindering your recovery.
The best neurologists in Brooklyn, NY, will likely emphasize the importance of limiting visual stimulation for anyone recovering from a concussion, but what could that limitation look like for you? The guide below explores the possible effects of screen time on concussion recovery.
How Screens Can Affect You Without a Concussion
You don’t have to be recovering from a concussion to experience some of the negative effects of constantly watching electronic screens. When you look at a phone, television, or computer screen, your eyes and brain must pay constant attention to the information they’re receiving. They also have to quickly process visual stimuli, which requires sustained cognitive focus.
This type of process can cause several negative effects, such as:
- Digital eye strain
- Headaches
- Blurry vision
- Difficulty focusing
- Sleep disturbances
- Light sensitivity
The symptoms a healthy person can experience with screen time overload are similar to post-concussion symptoms.
How Watching Screens Post-Concussion Can Affect Your Brain
According to a 2025 study published in Annals of Epidemiology, nearly 10 million Americans reported experiencing a traumatic brain injury within the previous year. Concussions fall within the broader category of traumatic brain injuries.
Following a concussion, the brain becomes more sensitive to visual stimulation. Common symptoms of concussions, such as nausea, headaches, and dizziness, may worsen when you watch screens too soon after an injury to the brain. Everything from focusing on text for long periods to watching fast-moving images can place additional demands on brain regions that are already working harder than usual.
The blue light that screens often emit can also be a problem. The light can interrupt the body’s melatonin production, preventing you from getting enough quality sleep. Sleep plays a role in cognitive rest, which is necessary for concussion recovery.
Another potential problem is noise. Some people experience headaches and other discomfort from the loud noises that electronic devices may produce.
What Happens if the Concussion Isn’t Immediately Detected?
Sometimes, post-concussion symptoms aren’t immediately obvious because the effects of the injury can be delayed. You might not experience anything until 24 to 72 hours after you sustain the head injury. Therefore, you might not feel the need to get a medical evaluation immediately following an accident.
It’s important to be seen by a doctor as quickly as possible after any accident that involves your head, even if you don’t experience symptoms. Concussions don’t always produce visible evidence of harm. However, an undiagnosed concussion may go unmanaged, allowing activities that worsen symptoms or increase the risk of another head injury.
When It May Be Possible To Use Screens Again
To minimize the risk of worsening post-concussion symptoms, avoid or significantly reduce screen time during the first 24 to 48 hours and take breaks if symptoms worsen as you gradually resume use. Taking this time to rest may support your brain’s healing by reducing eye strain and unnecessary cognitive load.
According to an article published in the Journal of Family Practice, a study of 125 teens and young adults found that those asked to avoid screens for the first 48 hours after a concussion had a median recovery time of 3.5 days, compared with eight days for those permitted screen time.
You can eventually reintroduce screen time under your doctor’s guidance. After the initial rest period, gradually increasing screen time according to your symptoms may be better tolerated than immediately returning to long sessions.
Recovery may take considerably longer when post-concussion symptoms persist. A study published in the Journal of Neurotrauma reports that 27% of patients with post-concussion symptoms lasting at least three months eventually recovered. Among those who recovered, 67% did so within the first year.
How To Manage Screen Time While You Recover From a Concussion
General guidance for managing screen use may include the following:
- Avoid or significantly reduce screen time in the first 48 hours.
- After the initial 24 to 48 hours, reintroduce screen time in short intervals that don’t significantly worsen your symptoms.
- Lower screen brightness or use night mode if bright light aggravates your symptoms, especially in the evening.
Your recovery from a concussion may differ from another person’s, so it’s best to follow your physician’s recommendations regarding screen use after a concussion.
