A little over a year ago, I wrote about a study that found women were more likely to suffer from health conditions associated with insomnia compared to men.
Another study has recently been published that comes with more bad news for sleep deprived women - particularly women with bipolar disorder.
Researchers analyzed data from 216 individuals that compared sleep quality with mood outcome over a period of two years.
They found that women with poor sleep quality were more likely to suffer from symptoms of depression and mania, and that poor sleep quality made these symptoms more severe.
For men, sleep quality had less of an effect - baseline depression scores and neuroticism were stronger indicators of mood outcome.
So why does sleep deprivation seem to affect women with bipolar disorder more than men?
It's thought that a biological mechanism could be to blame. One theory points the finger at reproductive hormones. Another theory suggests that women get a different type of sleep compared to men, so sleep deprivation affects them differently.
Either way, this study demonstrates the importance of sleep quality for those with bipolar disorder - particularly women.
