'Terrible for health': Bryan Johnson slams Indian coder's viral 4 am hustle post

US tech entrepreneur and anti-ageing advocate Bryan Johnson sharply criticised a viral social media post by an Indian web developer that appeared to glorify working through the night, warning that such a lifestyle was “terrible for health” and should not be seen as “heroic.”

The post in question was shared by web developer Priyanshu Tiwari, who posted a photo of a group of young tech workers coding late into the night. Alongside the image, Tiwari wrote, “It’s 4 AM guys, but builders are building. What’s your excuse.” The post quickly gained traction on X (formerly Twitter), amassing thousands of views and comments, with many users praising the dedication and work ethic of the young developers.

However, Bryan Johnson—known for his extreme longevity experiments and multimillion-dollar anti-ageing regimen—responded with a strong warning about the serious health implications of such work habits.

“It may feel heroic but you’re spending down your human capacity. That posture reduces brain oxygen by 30%,” Johnson wrote, referring to the image of young professionals hunched over their laptops.

He elaborated further on the physiological consequences of prolonged screen time and irregular sleep patterns: “The blue light suppress[es] melatonin, fragments deep-sleep, blunts next-day insulin sensitivity. The missed sleep raises cortisol, increases visceral-fat and decays memory.”
