Hugs certainly feel good, both on the giving and receiving end, and it turns out their effects are more than skin deep. A study by University of North Carolina researchers found that hugs increase the "bonding" hormone oxytocin and decrease the risk of heart disease.
Hugs are good for your heart, they lower blood pressure, and reduce stress, so make it a point to hug someone today.
In fact, when couples hugged for 20 seconds, their levels of oxytocin, released during childbirth and breastfeeding, increased. Those in loving relationships had the highest increases.
Meanwhile, levels of the stress hormone cortisol decreased in women, as did their blood pressure. Said lead researcher and psychologist Dr. Karen Grewen, "Greater partner support is linked to higher oxytocin levels for both men and women. However, the importance of oxytocin and its potentially cardioprotective effects may be greater for women."
Hugging for Your Heart
"Scientists are increasingly interested in the possibility that positive emotions can be good for your health. This study has reinforced research findings that support from a partner, in this case a hug from a loved one, can have beneficial effects on heart health," said Dr. Charmaine Griffiths, spokesperson for the British Heart Foundation.
Indeed, a previous study, also led by Grewen, found that hugging and handholding reduces the effects of stress. Two groups of couples were asked to talk about an angry event, but one group had previously held hands and hugged, while the others sat alone. It was found that:
• Blood pressure increased significantly more among the no-contact group as compared to the huggers.
• Heart rate among those without contact increased 10 beats a minute, compared to five beats a minute for huggers.
What's more, Grewen suggests that warm contact such as hugs and hand-holding before the start of a rough day "could carry over and protect you throughout the day."
Benefits of Touch Start Early
A hearty hug in the morning may help your loved one ward off stress all day.
Humans are clearly social animals, as evidenced by countless studies showing that those who have friends are healthier, as are people who are married.
We need social contact, and that includes touch, even beyond a couple's capacity. Take, for example, the fact that babies benefit from skin-to-skin contact with their mother with better physical development and positive bonding.
A telling example was a study of Korean infants in an orphanage. Those who received an extra 15 minutes of a female voice, massage and eye-to-eye contact, five days a week for four weeks, gained more weight and had greater increases in body length and head circumferences after the four weeks and at 6 months of age than children without the extra stimulation.
Therapeutic touch has also been shown to reduce stress and pain among adults, and reduces symptoms of Alzheimer's disease, such as restlessness, pacing, vocalization, searching and tapping.
Time to Get, and Give, More Hugs
"U.S. couples aren't very touchy feely in public," says Tiffany Field of the Touch Research Institute at the University of Miami Medical School. This is a shame as touch also releases two feel-good brain chemicals, serotonin and dopamine. Yet, according to Field's studies of U.S. and Parisian cafes, French couples spend three times more time touching than American couples.
