A wave of recent research reveals that even very short bursts of vigorous exercise — as brief as six minutes — can dramatically boost brain-derived neurotrophic factor (BDNF), the protein neuroscientists call "fertiliser for the brain." Complementary studies have uncovered a liver-to-brain signalling pathway that repairs the blood-brain barrier during exercise, while population-level analyses show that as little as 35 minutes of weekly activity can cut dementia risk by 41%, raising urgent questions about why 1.8 billion adults worldwide remain insufficiently active.
