What's fascinating is how many people think they know about good sleep hygiene, but they're missing some really basic stuff. Like did you know that if you drink coffee at two in the afternoon, a quarter of that caffeine is still bouncing around your system at two in the morning, or that your bedroom temperature might be the single biggest factor determining whether you actually fall asleep or spend an hour staring at the ceiling? These aren't just tips from some wellness guru. What's fascinating is how many people think they know about good sleep hygiene, but they're missing some really basic stuff.

Like there's this natural experiment that happens twice a year with daylight saving time, and Walker used that data to show how even losing one hour of sleep affects entire populations. Hard attack spike, car accidents increase. It's like watching what happens when you mess with millions of people sleep schedules all at once.
