More than half of the study participants had attempted suicide at least once in the past, and the 17% of the study group who had made an attempt within the previous month had dramatically higher scores in nightmare frequency and intensity than the rest. Bernert found that the relationship between nightmares or insomnia and suicide persisted, even when researchers controlled for other factors like depression.

...recent study by Walker and his colleagues examined how rest - specifically, rapid eye movement (REM) sleep - influences our ability to read emotions in other people's faces. In the small analysis of 36 adults, volunteers were asked to interpret the facial expressions of people in photographs, following either a 60- or 90-minute nap during the day or with no nap.

And the consequences are felt well beyond the region.
