(Newser) – Women tend to sleep longer and deeper than men, awakening less often in the night—but men are more likely to be satisfied with the quality of their sleep, reports the Wall Street Journal in an overview of the sleeping habits of the sexes. Because sleep plays such an important role in overall health, scientists are increasingly curious about these gender differences, which some suspect could go far in explaining why women live longer. "Women on average have longer sleep than men; women on average are healthier than men. It could be that those are related," said one professor.

Some things that are known: Men and women have different body clocks. Men's average "circadian period" of 24 hours, 11 minutes is six minutes longer than women's. Because women tend to get more deep sleep than men, they can endure sleep deprivation better. But scientists agree more research is needed—for example, women are 50% more likely to suffer from insomnia than men. Is that because of biology or because women are more likely to suffer from depression and anxiety, which can lead to insomnia?

I believe the woman suffer from the insomnia more because of the emotions and men feel stronger after sleep because they regain energy faster than women. But about women living longer I'd have to say it's because of their fat retention and ability to hold nutrients longer than men. If men were healthier and ate better to equate those levels they would live just as long if not longer than women. This is just based on my studies

I had a turkey sausage and egg biscuit with cheese for breakfast with some o.j. Three cups of coffee. My cat Morgan loves hanging out in the garage and prefers her catnip sprinkled in a container lid. I have two trees in my front yard, none in the back. I have some bushes though.
