SAN ANTONIO, June 10 (UPI) — Americans — especially women — are sleepier than Europeans and insufficient sleep causes excessive daytime sleepiness, U.S. researchers said.
Principal investigator Dr. Maurice Ohayon of Stanford University and director of the Stanford Sleep Epidemiology Research Center in Palo Alto, Calif., said nearly 20 percent of U.S. adults reported moderate to excessive sleepiness, 11 percent report severe sleepiness –13 percent in women and 8.6 percent in men.
“The number of individuals sleepy or drowsy during situations where they should be alert is disturbing,” Ohayon said in a statement. “Sleepiness is underestimated in its daily life consequences for the general population, for the shift workers and for the people reducing their amount of sleep for any kind of good reasons. It is always a mistake to curtail your sleep.”
The study involved 8,937 adults in Texas, New York and California, who were questioned about health, sleep problems and mental disorders.
The findings were presented at Sleep, the 24th annual meeting of the Associated Professional Sleep Societies in San Antonio.
