Researchers have known for a while about a connection between insufficient sleep and anxiety. A new study strengthens and quantifies this causal relation and shows that a sleepless night can raise anxiety by up to 30%.
Furthermore, the new study suggests that the deep phase of sleep is a natural anxiety reliever.
These are the main takeaways of a paper appearing in the journal Nature Human Behaviour.
Matthew Walker, a professor of neuroscience and psychology at the University of California (UC), Berkeley, is the senior author of the new study.
