A concussion is a mild traumatic brain injury that occurs when the brain moves or twists inside the skull, causing temporary changes in its function. This injury can affect how a person thinks, feels, acts, and sleeps. Rest, including limiting screen time, becomes an important part of the recovery process to allow the brain to heal.
Why Screens Hinder Concussion Recovery
Screen use can impede concussion recovery for several physiological reasons. Bright lights and rapid image movement on screens can exacerbate symptoms like headaches, eye strain, and light sensitivity (photophobia). The constant adjustment and focusing required by the eyes when viewing screens can also lead to visual fatigue and discomfort.
Processing information on screens demands continuous attention and interpretation, placing a significant cognitive load on a healing brain. This mental exertion can cause cognitive overload and fatigue, worsening symptoms like brain fog, dizziness, and nausea. Blue light emitted by screens can also disrupt natural sleep patterns by suppressing melatonin production. Adequate sleep is important for brain recovery, and its disruption can prolong healing.
Determining Your Screen-Free Period
There is no fixed answer for how long to avoid screens after a concussion, as the duration depends on symptom severity. Current recommendations suggest complete screen avoidance for the first 24 to 48 hours following the injury. Research indicates that abstaining from screens during this acute phase may lead to significantly shorter symptom duration, with some studies showing recovery in 3.5 days compared to 8 days for those who did not limit screen time.
After this initial rest period, the return to screens should be guided by symptoms; usage should increase only as symptoms improve and are tolerated. While complete abstinence may not always be beneficial long-term for mental well-being, excessive screen use can still prolong symptoms. Listening to one’s body and following medical advice are important for determining the appropriate screen-free period and gradual reintroduction.
Reintroducing Screens Gradually
Once initial symptoms have improved and the acute screen-free period is over, screens can be gradually reintroduced. Starting with very short durations, such as 5 to 15 minutes at a time, is advisable. Taking frequent breaks during screen use can help manage potential symptom flare-ups.
Adjusting device settings, such as dimming screen brightness or using “night mode,” can reduce visual strain and light sensitivity. It is also beneficial to choose less stimulating content initially, opting for activities like reading emails over fast-paced gaming or videos. Monitoring for any return or worsening of symptoms is important; if symptoms intensify, reduce screen time again. This process involves gradually increasing screen exposure based on individual tolerance.
Comprehensive Concussion Care
Beyond screen management, comprehensive concussion care involves a broad approach to recovery. Physical rest is important, meaning avoiding strenuous activities that could risk re-injury or worsen symptoms. Mental rest is equally important and involves limiting other cognitively demanding tasks, such as intense schoolwork or complex problem-solving.
Proper hydration and nutrition also support the brain’s healing process. If symptoms persist for more than two or three weeks, or if they worsen, seeking medical attention from a healthcare professional specializing in concussion care is advisable. These specialists can provide tailored guidance and additional treatments to support ongoing recovery.
