Takeaway
The relationship between getting up on a workday (GUw) vs. a free day (GUf), as well as the relationship between GUw and the peak time of the Per3 clock gene (P3PT) can be used to detect latent circadian rhythm sleep-wake disorder (LCRSWD).
Why this matters
This study provides criteria that can be used to identify individuals with LCRSWD who are otherwise hard to detect due to their apparent normal sleeping routines; from this, they can begin to access the correct treatment and management programs.
