Social Jetlag

Shrink Definition

Social jetlag is the mismatch between your body's internal clock and the schedule your social life demands, like sleeping late on weekends then forcing early wakeups on weekdays. It's like flying across time zones without leaving home. The recurring shift strains mood, focus, and health. Keeping wake times steadier narrows the gap.

Plain language

The gap between your body clock and your work-week schedule.

Shrink Insight

Shifting your sleep every weekend is like flying time zones without a trip.

Why it matters

It links irregular schedules to poorer mood, focus, and health, and points to a simple fix in steadier timing. It reframes weekend catch-up sleep as its own stressor.

Common misunderstanding

People think sleeping in on weekends fully repays the week. Large weekend shifts create a jetlag-like strain that can leave you groggier, not fresher.

Shrink Perspective

A steady clock beats a swinging one.
