If you’re a natural night owl, your biology may be working against your mental health. A landmark study published in Nature Communications — drawing on genomic data from nearly 700,000 participants — found that being genetically predisposed to late-night schedules is associated with higher rates of depression, anxiety, and schizophrenia.
The research, covered by Live Science, identified 351 genetic regions linked to being an early bird, revealing that your chronotype — whether you’re a morning lark or a night owl — is heavily influenced by your genes. This isn’t simply a matter of willpower or discipline.
Key Takeaways
- Your chronotype is largely genetic: Researchers identified 351 genomic regions associated with being a morning person. People with the most early-bird gene variants tended to fall asleep up to 30 minutes earlier than others.
- Night owls face higher mental health risks: The study found a causal link between being a night owl and increased susceptibility to depression, anxiety, and schizophrenia — independent of sleep quality or quantity.
- Society favors early risers: Part of the mental health burden on night owls may stem from living in a 9-to-5 world that doesn’t accommodate their natural rhythms.
- Practical adjustments can help: Nancy Rothstein recommends avoiding afternoon caffeine, disconnecting from technology an hour before bed, and filling that pre-sleep hour with calming activities like reading, gentle stretching, or mindfulness breathing.
You can’t change your genetics, but you can optimize your habits to work with your natural rhythms. For personalized strategies, explore our sleep resources and guided programs.
