Frequently Asked Questions
How much screen time is healthy?
Adults: 2-4 hours recreational. Kids 2-5: 1 hour. Teens: 2 hours. Work screen time is often unavoidable but take regular breaks.
How does screen time affect health?
Eye strain, disrupted sleep (blue light), poor posture, reduced physical activity, and potential mental health impacts from social media.
How can I reduce screen time?
Set app limits, create phone-free zones, use grayscale mode, replace scrolling with hobbies, and set specific check times instead of constant access.
Does blue light really matter?
Yes, blue light suppresses melatonin, the sleep hormone. Using screens within 1-2 hours of bed can significantly delay sleep onset and reduce quality.
How accurate are phone screen time reports?
Very accurate for that device. Screen Time Calculator - Daily Usage Tracker helps you combine ALL your screens (TV, Laptop, Tablet) for a total life picture.
Is all screen time bad?
No. Active screen time (creating, learning, video calling) is better than passive (mindless scrolling, binge-watching).
How much of my life will I spend on screens?
At 6 hours/day, you spend ~22 years of an average life looking at a screen. Screen Time Calculator - Daily Usage Tracker helps you visualize that impact.
Can screen time cause headaches?
Yes, 'Computer Vision Syndrome' causes headaches, dry eyes, and blurred vision due to reduced blinking and focusing effort.
How much water should I drink daily?
Daily water needs vary significantly by body size, activity level, climate, and diet. The commonly cited 8×8 rule (eight 8-oz glasses = 64 oz) is a rough average. A more personalized approach is to drink about half your body weight in ounces — a 160 lb person targets roughly 80 oz (2.4 liters). The National Academies recommend approximately 3.7 liters total daily water for men and 2.7 liters for women, including water from food (which contributes about 20%). Exercise, heat, altitude, and illness all increase requirements substantially — strenuous exercise in heat can require an additional 1-2 liters per hour. The simplest real-time indicator is urine color: pale straw yellow indicates good hydration; dark yellow or amber signals dehydration.
