LONDON: Inadequate slumber affects everyone's mood. But a new study has revealed that women who don't get agood night's sleep are likely to be grumpy than men.
A team of researchers has carried out the study and found that a bad night's sleep makes the fair sex far more grouchier than their male partner the next morning.
According to the researchers, poor sleep also has a harmful effect on the overall health of women more seriously than in men, and the effect is so marked that it could raise the risk of diabetes, heart attack and stroke.
"The study suggests that poor sleep -- measured by the total amount of sleep, the degree of awakening during the night, and how long it takes to get to sleep -- may have more serious health consequences for women than for men.
"We found that for women, poor sleep is associated with high levels of psychological distress, and feelings of hostility, depression and anger. These feelings were not associated with the same degree of sleep disruption in men," the British media quoted lead researcher Dr Edward Suarez of Duke University as saying.
The researchers studied 210 apparently healthy, middle-aged men and women without any history of sleep disorders.
Blood was taken and their psychological condition analysed. They found that about 40 per cent of the men and the women were classified as poor sleepers, defined as having frequent problems falling asleep, taking 30 or more minutes to fall asleep or awakening frequently during the night.
But while their sleep quality ratings were similar, men and women had dramatically different risk profiles.
Poor sleep in women was found to be linked to feelings of hostility, depression and anger far more than men.
Moreover, for women, poor sleep was found to be associated with higher levels of C-reactive protein and interleukin-6, measures of inflammation that have been associated with increased risk of heart disease, and higher levels of insulin.
"The results were so dramatic that of those women considered poor sleepers, 33 per cent had C-reactive protein levels associated with high risk of heart disease.
"Interestingly, it appears that it's not so much the overall poor sleep quality that was associated with greater risk, but rather the length of time it takes a person to fall asleep that takes the highest toll.
Women who reported taking a half an hour or more to fall asleep showed the worst risk profile," Dr Suarez said. The results of the study have been published in the 'Brain, Behaviour and Immunity' journal.
