The cold plunge protocol has become the most overhyped and simultaneously most under-optimized intervention in the 2026 biohacking landscape — and the gap between what’s claimed on social media and what’s actually proven in peer-reviewed research is larger than almost any other wellness topic. Ice bath sales on Amazon grew from under 1,000 units in … Read more

The context switching cost for AI builders just got a number attached to it that’s hard to ignore: $450 billion a year in lost productivity across the US economy, according to 2026 research extrapolating Gloria Mark’s UC Irvine work alongside Microsoft’s workforce studies. That figure was calculated before agentic coding tools became standard practice. The … Read more
Attention residue is the reason your deep work sessions feel shorter and shallower than they used to — even when your calendar shows the same number of blocked hours. Gloria Mark, Chancellor’s Professor of Informatics at UC Irvine, found that the average attention span on any screen has dropped to 47 seconds, with a median … Read more
