Screen time after a concussion: a symptom-guided approach

Phones, computers and TV often feel harder after a head injury. Current guidance favours a gradual, symptom-guided return to screens — not weeks of total avoidance.

Key takeaways

• Feeling worse on screens is common after a concussion and usually eases with time.
• Current guidance favours a gradual, symptom-guided return — not weeks of total screen avoidance.
• Short sessions with planned breaks tend to be easier than one long push.
• Protecting sleep matters: guidance suggests limiting screens before bed.
• Worsening confusion, weakness or repeated vomiting are urgent warning signs, not screen strain.

Get urgent help for warning signs

After a head injury, seek emergency care for increasing drowsiness or confusion, a seizure, weakness, trouble speaking, or repeated vomiting. These are not ordinary screen discomfort. See NHS head injury guidance and CDC danger signs.

This guide is not a way to diagnose or manage a concussion. If you suspect one, speak with a healthcare professional and follow their instructions about returning to work, study and daily activities, as the CDC's adult guidance recommends.

Why screens can feel harder

The CDC lists difficulty concentrating, sensitivity to light and feeling slowed down among common concussion symptoms — all of which can make bright, busy screens uncomfortable for a while. This is a recognized part of recovery for many people, not a sign of permanent damage.

Ease back gradually, guided by symptoms

The CDC advises taking it easier for the first one or two days, then gradually returning to usual activities while reducing those that make symptoms worse. Applied to screens: start with short, comfortable sessions, take a break when symptoms rise, and build up over days. You do not need to avoid screens entirely for weeks, and you do not need to push through severe discomfort.

Make screens gentler

• Lower brightness and increase text size so you are not straining to read.
• Prefer one calm task over fast switching between apps, feeds and messages.
• Use planned breaks — for example a few minutes away from the screen every 20–30 minutes — rather than waiting until symptoms spike.
• Choose audio (calls, podcasts, text-to-speech) on days when reading is hard.

These are comfort measures, not treatment. The CDC's symptom-guided approach is the reference point: if an activity reliably worsens symptoms, scale it back and discuss the pattern with your clinician.

Protect sleep from late-night screens

Sleep supports recovery, and the CDC suggests keeping a regular bedtime and limiting screens and loud music before bed. A simple rule — no bright screens in the last part of the evening — is easier to keep than a perfect routine.

Screens at work and study

If your job or studies depend on a computer, ask your clinician for written advice on returning, as the CDC recommends for demanding activities. The NHS advises seeing a GP if symptoms last more than two weeks or you are unsure about returning to work. Shorter blocks, a quieter inbox and a temporary reduction in screen-heavy tasks are reasonable things to raise with an employer.

How Memo complements this

A brief weekly note of how screens felt — which sessions were fine and which were not — makes appointments more useful. The concussion recovery check and tracking recovery after a head injury offer a gentle way to keep that record. Memo can show patterns over weeks; it cannot assess or manage a head injury.

Frequently asked questions

Do I have to avoid screens completely after a concussion?

Current CDC guidance does not call for weeks of total avoidance. It suggests easing back into activities after the first one or two days, letting symptoms guide the pace, and asking your clinician for individual instructions.

Why do screens give me a headache or make me nauseous?

Sensitivity to light and difficulty concentrating are common concussion symptoms listed by the CDC, and they can make screens uncomfortable for a while. If symptoms are severe, worsening, or last beyond two weeks, speak with a doctor.

When can I go back to computer work?

There is no fixed timeline. The CDC recommends a gradual, symptom-guided return and written medical advice before demanding activities; the NHS suggests a GP review if you are unsure or symptoms persist beyond two weeks.
