You're more likely to suffer from a mental-health disorder if you don't get enough sleep.
That's according to a new study published in the Proceedings of the National Academy of Sciences, which finds that "disturbing sleep and internal body clocks significantly contribute to psychiatric disorders."
"Sleep-circadian disturbances are the rule, rather than the exception, across every category of psychiatric disorders," says Dr. Sarah L.Chellappa of the University of Southampton, the study's senior author.
People with mental-health disorders are more likely to suffer from insomnia and hypersomnia, in which they find it hard to sleep at night but are sleepier in the daytime, than the general population.
About a quarter to a third of people with mood disorders have both insomnia and hypersomnia, where patients find it hard to sleep at night but are sleepier in the daytime.
"This variability in the duration and timing of sleep can lead to a misalignment between our body clock and our sleep-wake rhythms can increase the risk of sleep disturbances and adverse mental health outcomes," says Dr. Nicholas Meyer of King's College London, who co-led the study.
genes, exposure to light, neuroplasticity, and other factors were also examined
