A Partner's Touch Could Ease Our Pain

Those corny old love songs might be on to something after all. Scientists say the touch of a partner’s hand can both relieve pain and restore the physiological connection that pain interrupts. They published their findings in the journal Nature Scientific Reports.

Social animals love living in synch. Fireflies flash at the same time; predators prowl in unison toward their prey. Friends walking together unconsciously fall in step. Choir members’ hearts beat as one when they sing. Scientists believe these rhythmic connections may have developed to strengthen the community and the individual, making both more resilient and more likely to survive.

The same may be true of touch, a force so powerful that animals in experiments consistently choose it over food.

Pain researcher Pavel Goldstein of Cognitive and Affective Neuroscience Lab at CU Boulder had both these ideas on his mind in the delivery room as his wife gave birth to their daughter.

"My wife was in pain," he said in a statement, "and all I could think was, 'What can I do to help her?' I reached for her hand and it seemed to help," he recalls. "I wanted to test it out in the lab: Can one really decrease pain with touch, and if so, how?"

Goldstein and his colleagues set up a simple experiment, recruiting 22 long-term heterosexual couples. They brought the couples into the lab and hooked each person up to instruments to measure their heartbeat and breath. Some of the couples sat together, holding hands; some sat slightly apart; and some were seated in separate rooms.

Then the researchers zapped each woman’s forearm with a low amount of heat, just enough to cause pain, for 2 minutes.

Before the pain began, couples who sat in the same room experienced a concrete physiological connection. Their heartbeats and their breathing rates synched.

Then the pain came, and that connection went away—unless they were holding hands.

The same physical contact was also associated with decreased pain levels. Women hurt less when the men they loved took their hands.

The researchers can't say for sure why this is the case. "It could be that touch is a tool for communicating empathy, resulting in an analgesic, or pain-killing, effect," Goldstein said.

This study had its limitations. It was very small, and all the participants were young (23–32 years old). The experiments didn’t explore what would happen to men in pain, nor did they consider the question in same-gender couples. More research is certainly needed to validate these results. But for now, if someone you love is hurting, well, you know what to do.

The Northern Lights Storms Are Getting Names—and You Can Offer Up Your Suggestions

While all northern lights are spectacular, they’re not all spectacular in the same way. Aurora borealis, or “northern dawn,” occurs when electrons in the magnetic field surrounding Earth transfer energy to oxygen and nitrogen molecules in the atmosphere. The molecules then emit the excess energy as light particles, which create scintillating displays whose colors and shapes depend on many known and unknown factors [PDF]—type of molecule, amount of energy transferred, location in the magnetosphere, etc.

Though the “storms” are extremely distinct from each other, they haven’t been named in the past the way hurricanes and other storms are christened. That’s now changing, courtesy of a tourism organization called Visit Arctic Europe. As Travel + Leisure reports, the organization will now christen the strongest storms with Nordic names to make it easier to keep track of them.

“There are so many northern lights visible in Arctic Europe from autumn to early spring that we started giving them names the same way other storms are named. This way, they get their own identities and it’s easier to communicate about them,” Visit Arctic Europe’s program director Rauno Posio explained in a statement.

Scientists will be able to reference the names in their studies, much like they do with hurricanes. And if you’re a tourist hoping to check out other people’s footage of the specific sky show you just witnessed, searching by name on social media will likely turn up better results than a broad “#auroraborealis.”

Visit Arctic Europe has already given names to recent northern lights storms, including Freya, after the Norse goddess of love, beauty, and fertility, and Sampo, after “the miracle machine and magic mill in the Finnish national epic poem, ‘Kalevala.’” A few other monikers pay tribute to some of the organization’s resident “aurora hunters.”

But you don’t have to be a goddess or an aurora hunter in order to get in on the action. Anybody can submit a name (along with an optional explanation for your suggestion) through the “Naming Auroras” page here. It’s probably safe to assume that submissions related to Nordic history or culture have a better chance of being chosen, but there’s technically nothing to stop you from asking Visit Arctic Europe to name a northern lights show after your dog.
