The idea that sleeping in disrupts sleep is based on the concept of "social jetlag." Chronobiology research, notably studies on the circadian rhythm (meta-analysis, Roenneberg et al.), shows that significantly shifting your wake-up time on weekends weakens the synchronization of our internal biological clock. This can make falling asleep on Sunday night more difficult and create a feeling of fatigue on Monday, a well-documented phenomenon. However, the advice is nuanced: if an occasional sleep-in helps catch up on an acute sleep debt, it is beneficial, but it becomes counterproductive when practiced chronically. The creator simplifies a complex dynamic here into a binary statement. This is not a medical prohibition, but a recommendation aimed at stabilizing cycle regularity to improve overall alertness.

Linked to, not proven to cause.
What’s uncertain
The mortality link is from cohort data (associational), so other healthy habits of regular sleepers could contribute. The takeaway — keep timing consistent — is safe and low-cost regardless.
