I'm trying to catch up with the flood of oxytocin news in the past few months. This USA Today article discusses research at Brigham Young University and the University of Utah.
The study of young married couples began with some training on ways to increase closeness, but mostly, it studied the young-marrieds in their natural habitats.
The study found that massage and other kinds of loving touch reduced blood pressure and cortisol, especially among men, while raising oxytocin levels. At last, scientific proof that it's good to be nice to your spouse.
