Social Jet Lag

By the Swipe team, founded by Colin · how we make lessons
There's a name for the common pattern of a normal weekday wake time followed by a much later weekend one: social jet lag. It's not from crossing time zones — it's from your own schedule swinging back and forth between two different wake times every week.
The size of the swing matters. An hour or so of difference on a weekend is unlikely to do much; a swing of three or four hours starts to function like crossing a real time zone twice a week, without any of the travel — the clock has to keep re-adjusting.
None of this means weekends need to be identical to weekdays down to the minute — that's not realistic and isn't the point. The point is noticing the size of the gap, since a smaller, more consistent wake time across the whole week is what actually keeps the clock steady.
