That's a really good topic — lots of layers to it. Here’s a breakdown:
1. Sleep
-
Blue Light Exposure: Screens (phones, tablets, TVs, computers) emit blue light, which tricks your brain into thinking it’s still daytime. This delays the release of melatonin, the hormone that makes you sleepy.
-
Sleep Disruption: Using screens before bed can lead to difficulty falling asleep, lower sleep quality, and shorter sleep duration.
-
Nighttime Alertness: Even what you consume matters — doom scrolling
or intense gaming can keep your mind wired, making it harder to wind down.
2. Focus
-
Shortened Attention Span: Constant notifications, multitasking between apps, and the quick-switch nature of screens train the brain to expect constant stimulation. Over time, it can reduce the ability to concentrate on deep, focused work.
-
Task-Switching Costs: Each time you check your phone while working, your brain needs extra time to refocus — this is called "attention residue."
-
Digital Fatigue: Extended screen time can cause mental exhaustion, making sustained concentration even harder.
3. Mental Health
-
Anxiety and Depression: High social media use (especially passive scrolling) has been linked to increased rates of anxiety, depression, and feelings of loneliness.
-
Comparison Trap: Constant exposure to highlight reels of others’ lives can fuel feelings of inadequacy and low self-esteem.
-
Overstimulation and Burnout: Nonstop information from screens can overwhelm the brain, leading to chronic stress and emotional burnout.
Quick Tips to Protect Yourself
-
Screen Curfews: Avoid screens 1–2 hours before bed.
-
Blue Light Filters: Use "night mode" or blue light glasses in the evenings.
-
Digital Boundaries: Schedule screen-free breaks during your day.
-
Mindful Use: Choose active (creating, learning) over passive (scrolling, consuming) screen time.
