A University of California, San Francisco study published November 12 has linked irregular sleep-wake schedules to more severe symptoms of depression, anxiety and loneliness.

Researchers analysed data from approximately 23,000 participants, using months of wearable-device records from the TemPredict dataset.

Unlike earlier studies that primarily examined sleep duration and quality, the research focused on sleep regularity. Scientists developed a Sleep Regularity Index ranging from 0 to 100 to measure consistency in sleeping and waking times.

First author Severine Soltani explained that a score of 84 could indicate daily shifts in sleep timing of roughly an hour.

Senior author Ashley Mason said irregular schedules may disrupt circadian alignment.

Researchers noted that the relationship could work in both directions and called for further studies to determine whether more consistent sleep schedules can improve mental health.
