What does the screen bedtime cost over 30 years?
The Screen Bedtime
30 minutes, every night, for 30 years — the long-term cost is 228 days.
How the number's built.
Thirty minutes feels like a quiet transition. A way to wind down. But thirty minutes every night for 30 years becomes 5,475 hours — 228 full days of attention, spent staring at a screen in the dark while the body waited for rest.
Fifteen minutes of scrolling, not thirty.
114 days returned.
