Digital Fatigue: How Excess Screen Time Rewires Your Brain
Screens are a big part of our lives now, from the laptops we use at work to the doomscrolling we do once we log off. Digital devices are useful, but the mental toll is getting too high to ignore. Doctors claim that “digital fatigue” is no longer just a jargon term; it’s a real neurological disorder that affects how our brains work.
Understanding Digital Fatigue and Its Impact
HT Lifestyle spoke with Dr. Kunal Bahrani, Chairman and Group Director of Neurology at Yatharth Hospitals, to learn more about the severity of the problem. He thinks more people of all ages are coming in with headaches, cognitive fog, and irritability. “Digital fatigue” doesn’t just mean being fatigued after scrolling. Dr. Bahrani adds that too much information can overload the brain, making it challenging to remember things, stay focused, sleep well, and control your emotions.
The major problem is that people are continuously being pushed to do things. The brain isn’t designed to handle many emails, videos, and notifications at once. This “attention switching” wears out the neural circuits that help us make judgments. The result means our minds are in a shallow, reactive state rather than a deep, focused one.
The Side Effects of Digital Fatigue
If you spend too much time in front of a screen, you can become emotionally and physically exhausted. Dr. Bahrani says it boosts cortisol, the hormone that regulates stress in the body. Cortisol can impair memory, disrupt emotional balance, and weaken the immune system. This phenomenon is why people who take drugs a lot often feel uneasy and can’t sit still.
Another significant issue is difficulty sleeping. Melatonin is the hormone that signals the body to sleep. Blue light from screens blocks this hormone from functioning. This process prevents the brain from entering deep sleep cycles, which are crucial for healing and clearing waste proteins. This procedure starts a cycle of poor cognitive health.
Who is Most at Risk of Digital Fatigue?
Kids and teens are at the greatest risk. Their brains are adapting to fast-paced digital stimulation, so reading and other leisure activities seem boring to them. Teachers are already claiming that their students are more anxious and less attentive. But young professionals who spend a lot of time on screens are also in danger. They often feel weary in their bodies but can’t relax in their minds.
You need to make minor but continuous improvements to fix the situation. Making screen-free spaces before bed, taking breaks every 30 minutes, and spending time outside will help calm overactive neural circuits.
