According to the latest research from the University of California, Berkeley, sleeplessness can raise the level of anxiety disorders up to 30 %. Researchers have found that deep sleep is effective to cure anxiety and sleeping disorders. Matthew Walker, a UC Berkeley professor of neuroscience and psychology added: ” We have identified a new function of a deep sleep, one that decreases anxiety overnight by reorganizing connections in the brain”.They also suggest sleep as a natural remedy for anxiety disorders, which is most common among 40 million American adults and is rising among teens.
