Why Block Websites? {#why-block-websites}
23 Minutes
Average refocus time after digital interruption.
Source: Gloria Mark, “Attention Span” (2023)
Blocking websites removes the need for constant willpower. Instead of resisting temptation every time you see a distracting tab, you set a rule once and let technology enforce it.
The Science Behind It:
Research from the University of California, Irvine (Gloria Mark, 2023) shows that it takes an average of 23 minutes and 15 seconds to fully refocus on a task after an interruption. Frequent digital interruptions significantly reduce cognitive performance.

Expert Tips {#expert-tips}
💡 Expert Tip 1: Start Small
Don’t block 100 websites on day one. Start with your top five distractions. This improves long-term success and reduces frustration.
💡 Expert Tip 2: Use Schedules
Don’t fight your own rules during downtime. Use schedules so you can enjoy leisure time without frustration.
💡 Expert Tip 3: Pair Blocks with Replacements
When you block a site, replace it with a positive habit. Keep a saved reading list nearby, take a short walk, or practice a quick breathing exercise.
💡 Expert Tip 4: Review Weekly
If you keep searching for blocked sites, adjust your schedule. Flexibility helps you build a system that truly works for your life.
💡 Expert Tip 5: Use Multiple Layers
Combine router-level blocking with a browser extension. This creates redundancy and makes it harder to bypass your own rules.
