Bryan Johnson, known for his anti-ageing advocacy, recently took a 40-hour break from social media. In an X post, Johnson shared that his social media “fast” led to noticeable improvement in his mental and physical health.

Johnson described the break as his longest stretch offline in years and noted that the impact was both immediate and quantifiable.

“I noticed a calmed nervous system, improved sleep, better exercise performance, boosted mental clarity, better mood and greater presence,” he wrote, calling the experiment “a powerful longevity therapy; exactly what the evidence predicts.”

Johnson argued that scrolling through social platforms can be as harmful to the mind as junk food is to the body “The time away showed me that social media has similar effects on my body and mind as junk food,” he wrote.

He further explained how routine behaviours often trigger a cycle of cravings, gratification and regret. “Watching myself detox from social media, the pattern reminded me of overcoming a food addiction,” he wrote.

He said the break made him realise how much mental bandwidth social media had been consuming, with the constant urge to check feeds and engagement filling spare moments. “I was unaware of how much cognitive space social media was occupying,” he said.

He said he plans to make the social detox a weekly ritual, logging off from Friday evening to Sunday evening and urged others to adopt a similar routine. “I’m going to continue with the weekly social media fast and invite you to do it with me,” he wrote.

The post drew widespread reactions, with one user praising his approach.

One user wrote, “Best health and productivity hack ever. For 3 weeks now, I have been sleeping at 10 pm and waking up at 5 am for the 6 am gym, and working at 8 am. Once or twice a week on social media. Really does wonders for my physical and mental health.”

Another X user added, “People don't realise that it's actually hurting them physically. Unless you're using it for true connection or business purposes, phone time and social media are always wasted time.”

A third user said, “Great to see you have had this experience! I started doing regular social media detox in 2015, when Facebook was rather popular - never regretted it. Being offline…almost feels like a luxury.
