sleep and emotions

2013 brought scientific breakthroughs that deepened our understanding of the very nature of sleep, as well as important new information about Americans' sleep habits and the tools they use to help them sleep better.
The last finding is particularly interesting: A lack of sleep by one person in the relationship resulted in greater likelihood of diminished feelings of appreciation by both partners. This suggests just how deeply sleep can influence the emotional dynamic of a relationship.
There's still a great deal of information about the effects of sleep on the brain that we don't yet understand, so any research that sheds light on this subject is exciting and potentially important.
