Irregular Sleep Linked to Worse Anxiety and Depression
Researchers found stronger links to mental health symptoms when sleep timing was less regular over months of wearable data.
- A University of California, San Francisco study published Nov 12 links irregular sleep-wake schedules to more severe symptoms of depression, anxiety, and loneliness among approximately 23,000 participants.
- While previous research focused on sleep duration and quality, this analysis examined sleep regularity using months of data from wearable devices enrolled in the TemPredict dataset of more than 20,000 people.
- Researchers calculated a Sleep Regularity Index from 0 to 100, with Severine Soltani noting that "someone with an SRI of 84 might go to bed and wake up roughly an hour earlier or later than the previous day."
- Ashley Mason of the UCSF Department of Psychiatry and Behavioral Sciences noted that irregular sleep-wake timing may weaken circadian alignment, with the relationship between sleep and mental health potentially bidirectional.
- Other longitudinal research suggests irregular sleep may contribute to later poor health rather than being solely a consequence, prompting future studies to test whether regular sleep schedules improve mental health outcomes for participants.
