(CNN) — Yoga instructor Sadie Nardini and her husband got an early start on their New Year’s resolution: In December, the New York couple decided to have sex every day for the entire month.
Nardini and her husband, a professional photographer, initially decided to have sex like bunnies in the hopes that all the activity might help them overcome his-and-her bad habits: cigarettes and chocolate, respectively. And indeed, the nightly trysts did help. But they also found, unexpectedly, that frequent sex made them feel better in other ways, too.
Nardini says they both slept better and had more energy, and she didn’t get a cold or the flu all month as she usually does in the winter. “Sex doesn’t seem at first glance to be the cure for what ails you, but there’s so many health benefits of having more sex,” Nardini says. “Anyone can be better served by having more sex.”
In fact, the experiment was so successful, the couple plans to have daily sex in January, too.
Researchers have long known that not only is sex fun (when done with the right person, of course), but that people who have frequent sex tend to live longer and have healthier hearts and lower rates of certain cancers. These studies also show that men with an active sex life have healthier sperm, and sexually active women have fewer menopause symptoms.
