As women's brains work harder than men's, they also need more sleep



As women's brains work harder than men's, they also need more sleep


Women tend to require more sleep than men because of their “complex” brains, according to research.

Scientists found that around 20 minutes more sleep was needed by women compared to men - and said this was thought to be because the female brain works harder during the day.
The study was carried out on a sample set of 210 middle-aged men and women.
 "One of the major functions of sleep is to allow the brain to recover and repair itself," study author Jim Horne, a sleep expert formerly director of the Sleep Research Centre at Loughborough University, told the Mail Online.

"During deep sleep, the cortex — the part of the brain responsible for thought memory, language and so on – disengages from the senses and goes into recovery mode."

Prof Horn said the amount of sleep was necessitated by the complexity and intensity of brain activity during the day.

He said: "The more of your brain you use during the day, the more of it that needs to recover and, consequently, the more sleep you need.

“Women tend to multi-task — they do lots at once and are flexible — and so they use more of their actual brain than men do. Because of that, their sleep need is greater.

"The average is 20 minutes more, but some women may need slightly more or less than this."
However, he said men who have complex jobs which involve a lot of “decision-making and lateral thinking” are also likely to need more sleep than the average male.
The study also found that poor sleep among women was linked to a number of side effects.  Increased levels of psychological distress and greater feelings of hostility, depression, and anger were all found in women who slept poorly, but not men.

Women Absorb And Retain DNA From Every Man They Have Sex With

Women Absorb And Retain DNA From Every Man They Have Sex With Women retain and carry living DNA from every man with whom they have sexual intercourse, according to a new study by the University of Seattle and the Fred Hutchinson Cancer Research Center. The  study , which discovered the startling information by accident, was originally trying to determine if women who have been pregnant with a son might be more predisposed to certain neurological diseases that occur more frequently in males. But as the scientists picked apart the female brain, the study began to veer wildly off course. As it turns out, the female brain is even more mysterious than we previously thought. The study found that female brains often harbor “ male microchimerism “, or in other words, the presence of male DNA that originated from another individual, and are genetically distinct from the cells that make up the rest of the woman. According to the study: “ 63%...

This Woman’s Runny Nose Was Actually Spinal Fluid [ Must Read]

This Woman’s Runny Nose Was Actually Spinal Fluid 52-year-old Kendra Jackson from Omaha, Nebraska, had been suffering from a runny nose for quite some time. Her runny nose occurred two and a half years after she got into a serious car accident, but doctors didn’t see any correlation – they just put it down to allergies, however Jackson knew it was more than just that. Her runny nose started to worsen in 2015, “ When it didn’t go away, I kept going back and forth to the doctors, and they prescribed every kind of medicine you can think of, and my nose just kept on running ,” she said. After having a runny nose for more than two years, she went to see physicians at the University of Nebraska Medical Center earlier this year, and learned the real reason behind it. The physicians discovered that her nasal discharge was actually cerebrospinal fluid (CSF), leaking from a small hole in her skull that occurred when she had the crash. A rhinologist at the medical center, Dr. Chri...
