Sleep judged on morning tiredness

BERKELEY , Calif., March 6 (UPI) -- Insomniacs and normal sleepers define sleep quality by how tired or refreshed they feel upon waking and throughout the day, a U.S. study said.
Lead author Allison G. Harvey of the University of California at Berkeley said good sleep quality is associated with a wide range of positive outcomes such as better health, less daytime sleepiness, greater well-being and better psychological functioning.
"Moreover, poor sleep quality is one of the defining features of chronic insomnia. So it is surprising that there is minimal systematic research devoted to how humans arrive at their subjective sense of whether they had a good or poor nights sleep," Harvey said in a statement.
The researchers used a range of methods to compare the sleep quality judgments of insomnia patients and good sleepers.
The study results, published in the journal Sleep, found tiredness upon waking and throughout the day were most consistently associated with sleep quality judgments and individuals with insomnia appear to have more requirements to be met before they feel have experienced a night of good sleep quality.
The study compared the descriptions of good and poor sleep quality nights between 25 individuals with insomnia and 28 normal sleepers
