LONDON: Women who say they are simply too tired for sex may be the truth, not just fantasy. They operate on a biological clock sleep different for men and the need to go to bed earlier because of it, according to a new Harvard study.
Circadian rhythms of women who held six minutes faster than men, making them much more likely that early risers rather than night owls.
Jeanne Duffy, study co-author from Harvard, said: "What we found was that the cycle length of the biological clock in women was shorter on average than it was in men. The average difference was about six minutes."
Researchers from insomnia in women 50% more often than their male counterparts, especially the kind early morning when they wake up and can not fall asleep again, the Daily Mail But women can become chronic lack of sleep because they try to fight their sleep cycles and increasing too fast at night, before being awakened early in the light.
The results were published in the Harvard researchers at Brigham and Women;s Hospital, which is based on the results obtained with 157 people who have spent eight weeks to sleep in a windowless laboratory in Boston. They were completely isolated from the time signals from the outside world, so their body clocks to return to the natural circadian rhythm
