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.
