Furthermore, researchers also concluded that the quality of the relationship really didn't matter; just the amount of sex.
The study involved 129 women between the ages of 20 and 50. They were quizzed about their love lives, and then had their telomeres measured.
Telomeres are protective caps on the ends of DNA that can help determine how long a person will live. The telomores slow shorten over time as you get older.
So this basically means that the longer your telomeres are, the longer you'll live. Women in the study who had active sex lives also had telomores that were 30 percent longer.
"This is an important finding," the researchers said. "It provides new evidence that sexual intimacy within long-term relationships has health-enhancing benefits.''
It's not sure why this correlation is there, but one theory involves stress.
Stress is a believed cause of telomere depletion. Sex relieves stress, so that could be the key.0comments
Men were not tested, but sex is believed to have similar health benefits for them.
"We don't know whether the same finding would be seen in men," researchers said. "It may apply to men — there is no obvious reason why it should not."
