Scientists have long been keen to prove that love gives us health benefits,
too—beyond the obvious advantage of always having a date for New Year's Eve. Researchers can't say for sure that romance trumps an affectionate family or warm friendships when it comes to wellness.
But they are homing in on how sex, kinship, and caring all seem to make us stronger, with health gains that range from faster healing to living longer.
The benefits of love are explicit and measurable:
Protects your heart A University of Pittsburgh study found that women in good marriages have a much lower risk of cardiovascular disease than those in high-stress relationships.
Leads to a longer life The National Longitudinal Mortality Study, which has been tracking more than a million subjects since 1979, shows that married people live longer.
Plus, they have fewer heart attacks and lower cancer rates, and even get pneumonia less frequently than singles.
Helps beat cancer University of Iowa researchers found that ovarian cancer patients with a strong sense of connection to others and satisfying relationships had more vigorous "natural killer" cell activity at the site of the tumor than those who didn't have those social ties.
(These desirable white blood cells kill cancerous cells as part of the body's immune system.)
Some experts think it won't be long before doctors prescribe steamy sex, romantic getaways, and caring communication in addition to low-cholesterol diets and plenty of rest.
If that sounds like a happy Rx, here are ways to make the emerging evidence translate into real-life advice
The Benefits Of Bear Hugs:
Doctors at the University of North Carolina have found that hugging may dramatically lower blood pressure and boost blood levels of oxytocin, a relaxing hormone that plays a key role in labor, breastfeeding, and orgasms.
And the more you hug, the better: Women who hugged the most daily had the highest oxytocin levels, and their systolic blood pressure that was 10 mm/Hg lower than women with low oxytocin levels—an improvement similar to the effect of many leading blood pressure medications, says Kathleen Light, PhD, a professor of psychiatry at UNC and one of the study's authors.
"Getting more daily hugs from their husbands was related to higher oxytocin, and so the hugs were indirectly related to lower blood pressure," she says.
