How to Use This Calculator

Enter your daily work screen time (hours) and leisure screen time (hours) separately.
Set screen time before bed (minutes) — pre-sleep screens disrupt melatonin production.
Enter outdoor time (hours/day) to calculate the screen-to-outdoor balance ratio.
Review Total Daily Screen Time (hours) and Sleep Impact Score to quantify the burden.
Use Productivity Impact as a guide for setting healthier screen limits or scheduling regular breaks.
