Sleep deprivation has now been proven to not only cause a myriad of physical problems, but also mental health problems.
Those who have had a horrible nights sleep likely have experienced heightened anxiety the next day, especially if they are more prone to being worried.
Researchers at the University of California, Berkeley found that not getting enough sleep may increase blood flow to regions of the brain that contribute to excessive worrying.
Specifically targeted is the amygdala and insular cortex, which are both associated with emotional processing.
Those who are already anxious people are more likely to develop increased anxiety from insufficient sleep.
A professor of psychology, Matthew Walker, said, "These findings help us realize that those people who are anxious by nature are the same people who will suffer the greatest harm from sleep deprivation."
In the same vein, those who suffer from generalized anxiety disorder, panic attacks and post-traumatic stress disorder might benefit from sleep therapy, according to Neuroscience News.
