Always good to have a digital detox...
A recent study published in PNAS Nexus found that simply blocking mobile internet access on smartphones for two weeks led to significant cognitive improvements, including better focus and mood, comparable to reversing a decade of age-related cognitive decline, with participants engaging in more real-world activities like socializing, exercising, and hobbies.
▶️Key Findings of the Study
📑Cognitive Rejuvenation: Participants showed improved sustained attention, with results similar to being 10 years younger cognitively.
📑Mental Health Boost: Life satisfaction increased, and depression/anxiety scores decreased, with effects even stronger than some antidepressant studies.
📑Behavioral Shift: Without constant digital distraction, people spent more time in person with others, outdoors, exercising, reading, and resting, note the researchers.
▶️How It Works
📑Reduces Cognitive Overload & Multitasking: The internet, especially social media, bombards the brain with rapid-fire information and constant task-switching (multitasking), which taxes attention and executive functions. Disconnecting reduces this overload.
📑Improves Sustained Attention: Removing digital distractions allows the brain to practice focusing on one task, strengthening sustained attention—a skill often diminished by digital habits.
📑Boosts Real-World Engagement: Without internet access, people naturally spend more time socializing in person, exercising, and enjoying nature, all of which offer different, richer forms of cognitive stimulation than screens.
📑Enhances Sleep: Less screen time, particularly before bed, leads to better quality and longer sleep, which is crucial for cognitive restoration and memory consolidation.
📑Lowers Anxiety & Improves Presence: Digital detoxes decrease anxiety and stress, helping people feel more mentally present and in control
