You spend about a third of your life asleep — here's what's actually happening. This short course covers the stages your brain cycles through each night, the two forces that decide when you feel sleepy, what sleep genuinely does for memory and health (and where the popular claims outrun the evidence), the sleep myths worth retiring, and why jet lag, shift work, and teenage schedules fight your body clock. Evidence-graded; educational, not medical advice.
