Weekend sleep debt: the hidden cost of "social jetlag"
Staying up late and sleeping in on weekends shifts your body clock like crossing time zones — this mismatch is called social jetlag.
Why it backfires
A 2-3 hour shift on weekends makes Monday mornings feel like jet lag, and doesn't fully offset a weekday sleep deficit.
A better approach
- Limit weekend wake-up time to within 1 hour of your weekday schedule.
- Use a short nap instead of sleeping in — see our nap calculator.
- Check your real deficit with the sleep debt calculator.
