14 NOV 2026 · Two mornings: one under dim indoor light, one stepping outside within minutes of waking. The difference is a message carried not by vision, but by light sensors in the eyes most people have never heard of, straight to the brain's master clock. This episode follows how morning light sets the timing of your whole day, and the night that follows it, and ends with one change to try tomorrow morning. This episode includes AI-generated narration.

13 NOV 2026 · Practise a piano passage in the evening and it still trips you up — sleep on it, and in the morning it flows. This episode explains how stage-two sleep spindles replay a practised movement and write it into the cortex, following the research that found about twenty percent overnight improvement, and ends with the rule: practise in the evening, stop before frustration, and test in the morning. This episode includes AI-generated narration.

12 NOV 2026 · REM sleep replays the day's emotional memories while the brain's stress chemical drops to near zero — keeping the memory but stripping the sting. This episode follows the Berkeley research on sleep deprivation and the amygdala, and ends with a simple practice: after an upsetting day, write down only the facts, sleep, and revisit the decision in the morning. This episode includes AI-generated narration.

11 NOV 2026 · Deep sleep does more than rest the brain — slow waves drive blood out and pull cerebrospinal fluid in, washing away the day's metabolic waste. This episode follows the Boston University 2019 study that watched volunteers sleep in a scanner, and explains why protecting the first part of the night matters. Try it tonight: make the last hour before bed dim and quiet. This episode includes AI-generated narration.
