Sex is good for a woman’s memory
Women with a healthy love life perform better in tests
NEVER mind sudoku, crossword puzzles or so-called brain training games. The key to a healthy memory is regular sex – at least if you’re a woman.
Women who enjoyed an active love life scored better in tests measuring their working memory, according to a study.
Experts think it may partly be due to the effect sex has on the brain.
What’s even more surprising than the results is that only one of the three scientists who came up with them, is a man.
For the research, the team of experts at McGill University in Montreal, Canada, recruited 78 young women aged 18 to 29.
They were quizzed on their sex lives before undergoing a series of memory tests.
The tests involved looking at a group of 60 words and faces before later being asked to pick them out from a larger group of 90 words and faces. The idea was to measure their short-term recall, a measure of memory function.
The results, published in Archives of Sexual Behaviour, revealed that the women who enjoyed the most frequent sex registered the highest scores on the memory tests.
But the effect was much more noticeable when it came to remembering words rather than faces, researchers said.
This was probably because word recall is largely handled by the hippocampus, while other brain regions control facial recognition.
Scientists said this lent support to the theory that regular sex bolsters neurons in the hippocampal region. In a report on their findings researchers said: “Neurogenesis in the hippocampus is higher in those women with a higher frequency of intercourse.
“These results suggest sex may indeed have beneficial effects on memory function in healthy young women.
“They support the hypothesis that frequency of sex is positively associated with memory scores.”
Although the study only recruited women, previous research has hinted that men’s brains benefit as much, if not more, from plentiful sex.
Animal studies have previously suggested that frequent sex stimulates a process called neurogenesis – the growth of new cells and tissue – in the hippocampus, the part of the brain involved in controlling memory.
A healthy love life also boosts levels of feel-good chemicals in the brain, called neurotransmitters.
Earlier this year, experts at Coventry University found that men and women in their fifties, sixties and seventies who had an active love life had a lower risk of dementia.
The study of nearly 7000 older people showed women who had regular sex scored up to 14 percent higher in word challenges, while the most sexually active men scored 23 percent higher.
Scientists are desperately trying to find ways to preserve brain function in old age.
Alzheimer’s and other types of dementia recently emerged as the UK’s biggest killer, pushing heart disease into second place. The “epidemic” has triggered a boom in sales of brain training computer games to those who are terrified of future illness.
But a recent review of 130 studies found little evidence that exercises for the brain had long-term benefits. – Daily Mail
