From early mornings spent staring at laptops to late nights scrolling endlessly through social media, screens have woven themselves deeply into our everyday routines. But have you ever paused to consider what this constant screen exposure is doing to your brain?
Excessive screen time isn’t just a matter of sore eyes or stiff necks — it can seriously affect your brain’s cognitive performance, memory, and even long-term neurological health. In a recent conversation with HT Lifestyle, neurologist Dr. Praveen Gupta shed light on how screen addiction impacts the brain and how we can proactively protect ourselves.
According to Dr. Gupta, overexposure to screens can lead to the thinning of the cerebral cortex — the outer layer of the brain responsible for memory, decision-making, and problem-solving. This can significantly heighten the risk of conditions like early neurodegeneration, dementia, strokes, and Parkinson’s disease. Studies suggest that adults who spend more than five hours a day watching screens or engaging with smartphones tend to have reduced gray matter — the brain tissue essential for emotion regulation, movement, and memory.
In addition, smartphone and social media usage has become alarmingly dominant, consuming nearly half of mobile screen time and over 25% of waking hours for most individuals.
To combat the damaging effects of prolonged digital exposure, Dr. Gupta offers the following science-backed prevention tips:
1. Cut Down on Digital Fatigue:
Balance, not avoidance, is the key. Alternate screen-based tasks with offline activities to reset your brain and boost productivity.
2. Limit Screen Exposure Effectively:
Use the 20-20-20 rule: every 20 minutes, shift your gaze to something 20 feet away for 20 seconds. Follow the 50/10 rule: 50 minutes of work followed by a 10-minute break. Activate Do Not Disturb mode while working.
3. Decrease Blue Light Exposure:
Switch your screen to night mode or install a blue light filter. Consider using blue light-blocking glasses. Replace late-night scrolling with reading or relaxing rituals to support better sleep.
4. Make Real-Life Connections a Priority:
Spend quality screen-free time with friends and family. Take daily walks, engage in physical activities, and prefer in-person or voice interactions over text messaging.
5. Adjust Screen Settings for Comfort:
Modify brightness and contrast to reduce eye strain. Maintain a one-arm distance from screens. Use eye drops if dryness occurs and remember to blink frequently.
6. Embrace Digital Mindfulness:
Use app limits and grayscale settings to reduce screen addiction. Turn off non-essential notifications to minimize distractions.
7. Give Your Mind a Rest:
Take time to meditate, breathe deeply, and disconnect before bed. Build a tech-free bedtime routine and explore offline hobbies such as sketching, journaling, or reading.
Staying mindful about your screen habits can protect your mental sharpness, support better emotional health, and improve sleep quality. A few small changes in your daily routine could make a lasting impact on your cognitive well-being.
