Can a simple tweak on your phone really make your brain feel a decade younger? A recent study by the university of british Columbia says yes. Researchers found that turning off one key phone setting—mobile internet—can improve focus, mood, sleep, and even cognitive performance to the level of someone ten years younger.

Here’s a detailed breakdown of what the study revealed and how you can apply it to your daily life.


1. The Study That Changed How We See Smartphones

  • Conducted on 467 iphone users and published in PNAS Nexus.
  • Participants didn’t give up their phones—just turned off mobile data or used an app to block internet access.
  • After a month, they reported improved cognitive health, focus, and happiness—similar to people a decade younger.


2. Improved Focus & Mental Clarity

Constant notifications and endless scrolling create attention fragmentation.

  • Turning off mobile internet reduces distractions and helps the brain sustain focus longer.
  • Tasks are completed faster and with greater accuracy when the mind isn’t interrupted.


3. A Natural Mood Booster

Less exposure to online stressors like social media comparisons and negative news leads to a better mood.

  • Participants reported increased happiness and life satisfaction.
  • Reduced anxiety and fewer mood swings were also observed.


4. Better Sleep Quality – More Rest for Your Brain

Screen time before bed is a major cause of poor sleep.

  • Disabling mobile internet cuts down late-night scrolling.
  • Participants slept 17 minutes longer on average, improving overall rest and brain recovery.


5. Stronger Real-Life Connections

With mobile data off, people are more likely to spend time with friends, family, and engage in face-to-face conversations.

  • Offline time fosters emotional bonding and meaningful interactions.
  • It also encourages outdoor activities and hobbies that stimulate mental health.


6. Comparable to Cognitive Behavioral Therapy (CBT)

The study revealed that this small lifestyle change had effects similar to Cognitive Behavioral Therapy (CBT).

  • CBT is known for enhancing mental health by changing daily habits.
  • Turning off mobile internet achieves similar benefits—without professional intervention.


7. How to Turn Off mobile Internet – Step by Step

For Android:

  • Open Settings → SIM cards & mobile networks or Connections.
  • Tap Mobile Data and switch it Off.

For iPhone:

  • Open Settings → Cellular → Toggle Cellular Data Off.
  • Or disable via Control Center.

Tip: Keep Wi-Fi on if needed, but avoid unnecessary browsing to maximize benefits.


Final Takeaway

A tiny change in your phone settings can deliver younger brain performance, better sleep, and improved mood. Try switching off mobile internet for a few hours daily—or an entire weekend—and feel the difference.
