There are multiple reasons why your computer screen might be giving you headaches or migraine attacks. Why do computer screens worsen headaches? Existing eye disease or disorder (e.g.In addition to these underlying condition, there may be other risk factors to watch out for if computers bring on regular headaches: And if post-concussion headaches persist, then longer-term solutions must be identified in order to safely work on a computer. 9 As a result, medical professionals often recommend a period of physical and cognitive rest immediately after a concussion-this often involves limiting screen time from electronic devices and computers. Certain treatments (specifically neurofeedback) that involve computer use may even be rendered less effective in halting headache symptoms due to the mandatory screen exposure. In addition, LCD screens were shown to slow the recovery time for post-concussive individuals. And there are countless anecdotes online that further reinforce the health concern of computer usage after a concussion or brain injury: For example, nearly all of the post-concussion and TBI respondents (98%) of our survey acknowledged that digital screens were particularly bothersome. There is far less clinical evidence available that notes the impact computer screens have on post-concussion syndrome and traumatic brain injury (TBI), but patients are vocal about the negative effects that too much screen exposure can have on their symptoms. 6 Why are screens bad for concussions and brain injuries? 6-8 In fact, nearly half of school-aged children experienced migraines in direct response to computer activity-making it the most common environmental trigger. Numerous studies have revealed that digital screens and computers are risk factors for the onset of migraine attacks in younger persons. Our survey of light-sensitive individuals last year revealed that 85% believed LED and LCD screens played a significant role in the frequency and severity of their attacks.Ĭhildren and adolescents may be even more susceptible to migraine attacks from computer screen exposure.
5 Anecdotal evidence however suggests these numbers may be especially low. Early studies have suggested that computer screens may worsen migraine or headache-related symptoms in one-third of patients researchers also discovered that it may lead to attacks in 14 percent of migraineurs. 1,3 Can computer screens trigger migraines?Ĭomputer screen time can have serious consequences for a person with migraine, especially if light is a trigger and/or if photophobia is otherwise a prominent symptom. 1,4,10 Workers who specifically use the computer as a primary function of their job have also been found to have more headache episodes, although just a few hours of constant use for an extended time period can have the same effect.

Researchers from across the globe have found that between 19% to 53% of those with extended exposure to their PC or laptop screen suffer headaches as a frequent side effect in many cases, recurring headache symptoms lasted a week or more. 2Īmong those with CVS symptoms, headache is frequently cited as the most prevalent-even though, ironically, it is not directly related to the eye. Most often it is linked to computer vision syndrome, or CVS for short, which specifically refers to visual and other symptoms that result from screen exposure and which may affect as many as 90% of computer users. The unfortunately truth is that headaches or migraine attacks from the computer screen are a common occurrence, but researchers have had a difficult time pinpointing just how widespread it is for the general population. It is likely that we all have dealt with the following scenario at one time or another:
How common are headaches from computer screens? Many of us have likely felt sick after staring at the computer screen for too long, but what about headaches? And how does computer use affect people who may already be sensitive, such as a patient who has been diagnosed with chronic migraine or post-concussion syndrome? We take a look at the factors that may contribute to a common phenomenon that is often referred to as computer screen headache.
