Scientists are rethinking the cause of insomnia

A gut reaction might be causing your sleepless nights

- 

Your gut microbes could be causing your insomnia, according to a new study from scientists in China. The study says the reverse is also true: your sleep habits could impact your gut health.

Previous research had already suggested that sleep habits and gut health could be interlinked, but the recent analysis published in the journal General Psychiatry indicates that the link might be causal — meaning your sleep might directly influence your gut, and vice versa.
