Research Suggests Loneliness Is As Bad for You as Smoking Nearly a Pack of Cigarettes a Day

Humans are social animals. That means that our friendships, family, and other social networks are not just pleasures; they're also essential to our survival. New research presented at the 125th Annual Convention of the American Psychological Association finds that loneliness and isolation may be bigger public health issues than previously realized.

"Being connected to others socially is widely considered a fundamental human need—crucial to both well-being and survival," psychologist Julianne Holt-Lunstad of Brigham Young University said in a statement.

"Extreme examples show infants in custodial care who lack human contact fail to thrive and often die, and indeed, social isolation or solitary confinement has been used as a form of punishment."

A 2010 AARP study of adults aged 45 and up found that more than one-third of respondents felt lonely, and that loneliness and poor health went hand in hand.

To quantify the impact of loneliness and isolation, Holt-Lunstad conducted two separate meta-analyses of the scientific literature, reviewing a total of 218 studies. Her first analysis found that higher social connectedness is linked to as much as a 50 percent decrease in risk of early death.

The second, which included data from more than 3.4 million people in North America, Europe, Asia, and Australia, suggests that social isolation, loneliness, and living alone can be as bad for a person's health as other common risks. (The AARP study also concluded that prolonged isolation carries the same health risks as smoking 15 cigarettes per day.)

"There is robust evidence that social isolation and loneliness significantly increase risk for premature mortality, and the magnitude of the risk exceeds that of many leading health indicators," Holt-Lunstad said.

"With an increasing aging population, the effect on public health is only anticipated to increase. Indeed, many nations around the world now suggest we are facing a 'loneliness epidemic.' The challenge we face now is what can be done about it."

To combat loneliness, experts recommend strengthening existing relationships, scheduling regular phone dates with friends, and signing up to volunteer or otherwise help build community.

Carla Perissinotto is a geriatrician and researcher at the University of California, San Francisco. "Maintaining connections, that touchy-feely thing, is actually really important," she told NPR. "It's hard to measure, it's hard to quantify, but there is something real."

The Unkindest Cut: The Chainsaw Was Invented to Assist With Difficult Childbirths

There’s always a price to be paid for innovation. Usually that amounts to some sleepless nights and lots of trial and error. But sometimes it means attempting to deliver babies with a chainsaw.

This dark chapter in agricultural history comes from Popular Science, which recently detailed how the motorized cutting tool populating Home Depot shelves came to be. In the 18th century, two Scottish surgeons named John Aitken and James Jeffray devised a solution they could employ when faced with difficult childbirths. Rather than use a knife to widen the pelvic area by slicing through cartilage and bone to extricate a stuck baby, the two developed a chainsaw to make cutting easier.

While this sounds ghastly, the doctors were actually trying to lessen the agony endured by women who needed their pelvic bone separated. The knife took a long time, while their device—a modified knife with serrated “teeth” on a chain—could cut through bone and tissue more quickly.

If circumstances warranted it, the doctor would grab the saw, which had a handle on both ends, and wrap the chain around the pelvic bone, pulling each handle so the chain would cut into the bone. Later, the device was outfitted with a hand crank. Thanks to this innovation, difficult births could be described as merely agonizing as opposed to extended torture.

The procedure was dubbed a symphysiotomy and remained in use in the medical field as surgeons noticed how efficiently it could work in other circumstances, like amputations. It lasted through much of the 19th century as part of a surgical toolbox until C-sections grew in popularity. In the 20th century, the principle was commandeered for less disturbing purposes like logging, with two-person saws weighing more than 100 pounds each. By the 1950s, those gave way to lighter models.

For all its discomfiting history, at least the chainsaw proved to be useful—which isn't something that can be said for all inventions purporting to aid in childbirth. In 1965, George and Charlotte Blonsky patented a device that acted as a human turntable, spinning so quickly it might induce the patient (or victim) into delivering their baby via centrifugal force.

Kane Tanaka, World’s Oldest Living Person, Just Celebrated Her 117th Birthday

Less than a year after being named oldest living person in the world, Kane Tanaka has reached a new milestone. As Reuters reports, Tanaka celebrated her 117th birthday on January 2, 2020, extending the Guinness World Record-winning streak she set in March 2019.

Kane—the seventh of eight siblings—was born on January 2, 1903 in Fukuoka, Japan. She married Hideo Tanaka in 1922, and the couple had five children. Today, she is a grandmother to five and a great-grandmother to eight.

Tanaka celebrated her birthday at the Fukuoka nursing home where she resides, surrounded by friends and family. After taking a bite of her birthday cake, she reportedly said, “Tasty, I want some more." On a typical day, Tanaka spends her time studying math, practicing calligraphy, and beating the nursing home staff at board games.

The 117 club is an exclusive group only a handful of women has entered in recent history. In the last few years, Emma Morano of Italy, Violet Mosse Brown of Jamaica, and Nabi Tajima and Chiyo Miyako of Japan all reached age 117 and were each the oldest person alive for a brief period. If Tanaka celebrates another birthday next year, she will be the first person since the 1990s to live to 118.
