You finish a day packed with video meetings and somehow feel completely exhausted, even though you have barely moved from your chair. Concentrating becomes harder, simple decisions feel like work, and the thought of opening another email is enough to make you want to close the laptop altogether.
This feeling is increasingly described as “brain fatigue” or “Zoom fatigue”. Video calls themselves do not damage the brain, but spending several hours in back-to-back virtual meetings can place considerable cognitive and visual demands on us. Dr Kunal Bahrani, Neurologist, explains why a workday spent on video calls can leave you mentally drained and what can help.
Why can video meetings feel so tiring?
A video meeting may look like a relatively passive activity. After all, you are sitting in one place. But your brain is doing much more than simply listening.
As Dr Bahrani explains, “A video call may look like a passive activity because we are sitting in one place, but the brain is continuously working.” You are listening, watching facial expressions, processing information, deciding when to speak and often monitoring your own reactions at the same time.
When that continues for several hours without a proper break, mental fatigue is understandable.
An in-person meeting often has natural pauses. You may look away from the speaker, change your posture, walk to another room or simply have a few moments when intense concentration is not required.
Video meetings can remove many of those pauses.
Back-to-back meetings leave little room for the brain to reset
The problem becomes more noticeable when meetings are scheduled one after another.
One call ends at 11 am and another begins at exactly 11 am. There is no time to stand up, get some water or simply step away from the screen.
Even the gap between meetings may disappear into replying to emails or messages.
Lunch can become another meeting, with someone listening to a presentation while eating. The result is a workday in which the brain rarely gets a genuine pause.
That constant switching between listening, responding and processing information can leave you feeling mentally exhausted by the end of the day.
It may not be the screen alone causing your headache
Spending long periods in front of a screen can come with several other issues.
Sitting for hours can mean less movement, poor posture and tension in the neck and shoulders, while prolonged screen exposure can contribute to visual strain. Together, these factors can contribute to discomfort and headaches.
For people who are already prone to migraine, other aspects of the workday can add to the problem.
Inadequate sleep, dehydration, missed meals, stress and prolonged screen exposure can combine to make headaches more likely.
Dr Bahrani says it is important not to look at screen time in isolation.
“We need to look at the person's complete routine,” he explains, including sleep, regular eating and drinking, movement and the number of hours spent continuously in front of a screen.
The simplest solution may be to leave some space in your calendar
You do not necessarily have to give up video calls.
Instead, the way meetings are scheduled and used may need to change.
If possible, avoid filling every available slot with a meeting. A gap between two calls should ideally be an actual break rather than another chance to check email.
Stand up. Walk around for a few minutes. Drink some water. Look away from the screen.
And if a meeting does not require video, consider whether an audio call would be enough.
These may sound like very small changes, but they can help interrupt the cycle of continuous concentration.
Don't turn lunchtime into another meeting
Working through lunch can feel productive, particularly on a busy day.
But eating while listening to a presentation does not necessarily provide the kind of pause your brain and body need.
Dr Bahrani's advice is to protect meal times rather than treating them as another available slot for work.
Even a short period away from the screen can make the workday feel less like one continuous stretch of concentration.
When should you look beyond ‘screen fatigue’?
Feeling mentally tired after a long day of meetings is not necessarily a cause for concern.
However, persistent or unusual symptoms should not automatically be blamed on video calls.
According to the source, frequent headaches, significant concentration problems, memory difficulties, dizziness, excessive daytime sleepiness or fatigue that continues despite adequate rest may have other causes and should be evaluated if they persist or worsen.
This is particularly important if symptoms are affecting your daily life rather than occurring only after an unusually busy day.
Your calendar needs recovery time too
The modern workday often treats every empty calendar slot as an opportunity to fit in one more call or task. But the brain needs periods of lower stimulation too.
Dr Bahrani puts it this way: “Technology is not the enemy here.” Virtual meetings have become a normal part of work and communication. The problem is expecting the brain to remain continuously engaged for hours without giving it time to recover. So the next time you see a 10-minute gap between two meetings, resist the urge to fill it.
Stand up. Get some water. Look away from the screen. Take a few quiet minutes. Those ten minutes may look unproductive on your calendar, but they could be exactly what your brain needs to return sharper for the next meeting.
