Researchers from the University of California documented the sexual activity of 129 women between 20 and 50, before taking blood tests to determine their long-term health prospects.
They found that participants who had regular sex had significantly longer telomeres – the protective caps on the ends of DNA that can predict a person’s biological age.
Without these telomeres, DNA strands become damaged and their abilities diminished. Shorter telomeres have been associated with ageing, disease and higher risk of death. So basically, the longer they are the longer you’re likely to live.
“This is an important finding," Researcher Dr Aric Prather said. “It provides new evidence that sexual intimacy within long-term relationships has health-enhancing benefits.’’
"The comparison was between women who had sexual intimacy in the previous week and those who had not," he explained.
"It is possible the greater the frequency of sexual intimacy, the stronger the effect, and we plan to investigate that at a later date.”
