Researchers at Duke University Medical Center say that women are twice as likely to report sleep problems than men, and the health problems associated with poor sleep are twice as likely to affect women.
"We found that for women, poor sleep is strongly associated with high levels of psychological distress, and greater feelings of hostility, depression and anger. In contrast, these feelings were not associated with the same degree of sleep disruption in men.
In the study, women who reported poor sleep had the highest level of biomarkers associated with heart disease. It also found that the length of time it took to fall asleep was more important than overall sleep quality. Women taking more than a half hour to fall asleep are at the highest risk.
