Hysterical strength allows someone to lift a car off their child

Stress-induced adrenaline can trigger a 'hysterical strength' response

The stress response is a powerful ancient mechanism designed to maximize human survival—it can even result in superhuman strength. The adrenal glands are located just above the kidneys, and stress-induced adrenaline release causes more blood (and therefore more oxygen) to flow to your muscles, increasing performance.

How to carry more than your own bodyweight

Those images showing a villager carrying an enormous bundle on their back, or balancing a basket of fish on their head—how's that possible? This article dives into the clever tools and habits of strength training some cultures employ as part of their labors, from the springy bamboos used by Vietnamese farmers to the headbound burdens of Himalayan sherpas.

The Lazarus Effect is when a heart begins beating on its own after declared death

Formally called autoresuscitation, this rare phenomenon occurs when someone is declared dead following a cardiac arrest but their heart beats again without help—making it seem like the person came back to life. Doctors don't know the exact cause.

F1 driving requires intense strategy, endurance, and strength

Formula 1 cars are the peak of human engineering, and the humans driving them must have exceptional skills to master their cars. This Wired video talks to former performance coach Clayton Green to uncover what makes Formula 1 drivers such unique athletes. Learn why drivers focus on neck strength to combat extreme g-forces, and what those forces do to a driver's body over a race.

On March 12, 2006, 19-year-old Matt Suter was lifted into a tornado while inside a mobile home in Fordland, Missouri. Despite traveling 1,307 feet, his only significant injury was a head wound caused by being hit by a lamp prior to being transported.

Memes can turn regular people into unwitting celebrities

When Charles Ramsey heard loud banging from his neighbor's house, he peeked outside and saw a woman trying to escape. After helping the abducted woman get free, he gave an interview that became a viral autotuned meme. This podcast explores the unintended consequences of that relationship and its racial overtones.

Grip strength, how firmly and securely you can hold onto things, predicts death better than blood pressure

'Carry That Weight' was a college performance piece that went viral

Columbia University undergrad Emma Sulkowicz became an overnight sensation with their senior thesis performance art piece "Carry That Weight." Emma developed the piece after reporting having been sexually assaulted by another Columbia student to the school, which declined to find that student responsible. In "Carry That Weight," Emma carried her mattress everywhere with her for the entirety of her senior year, calling it an “endurance performance art piece.”

Strength training doesn't require fancy equipment—cans, water bottles, and shopping bags work well.

World records are often broken later in the day—and scientists wonder if muscle clocks explain the difference.

The body's response to cardiac arrest has been linked to near-death experiences.

The impact of gravitational force on our bodies surprised early coaster riders and engineers

There is only a certain amount of gravitational force that the body can handle before dealing with consequences like short-term vision loss or unconsciousness. Increased scientific understanding has largely reduced these impacts, with engineers combining periods of intense pressure with periods of relief.

Grief rewires the human brain

The human brain handles stress and emotional traumas similarly. In response to the emotional stress of a situation like the death of a loved one, divorce, or abuse, the brain may strengthen or weaken connections between nerves to form new neural connections. Over time, chronic stress can diminish brainpower, reducing overall nerve growth and memory to shift resources to enable elevated fear responses and enable humans to survive.

Arnold Schwarzenegger fueled a lot of the interest in strength training, beginning in the 1980s.

The anatomy of 'Mashle,' as described by a doctor

"Mashle: Magic and Muscles" is a manga and anime in which a seemingly magicless man performs outsized feats he blames on "muscle magic." In this 15-minute video, a doctor breaks down the anatomy and biomechanics of some of the feats performed by Mash, the series' main character who's spotted flying a broom via leg pumping and reading magical texts while sitting in an invisible chair (i.e., single-leg squat).

Why so many people love roller coasters even though they’re scary

When a threat arises, it triggers our bodies to go into fight-or-flight mode and prepare for danger. However, when no obvious threat to our safety is present, this natural high can become enjoyable. Some people are more likely to enjoy these thrills based on factors like individual brain chemistry or physical health.

Hacking the body for a future that didn't happen

Journalist Adi Robertson experimented with one of the most accessible biohacks: magnets. Having a tiny magnet in their right ring finger meant they could sense magnetic fields, attract small metal objects, and more. But magnets weaken over time, eroding this new sense. Such implants do more than offer a new way of interacting with the world, they also pose new complications, such as the inability to get an MRI.

Why does the body have a stress response?

When encountering a stressful situation, the human body typically goes into what is known as "fight-or-flight" mode. Because it evolved as a survival mechanism, the biochemical response enables people and other mammals to react quickly to life-threatening situations. The carefully orchestrated yet near-instantaneous sequence of hormonal changes and physiological responses helps someone to fight the threat off or flee to safety.

Goose bumps are often triggered by emotions

A physiologist and professor of zoology explains that the subconscious release of adrenaline, a stress hormone, causes a contraction of skin muscles. It’s released in several situations, including when humans are cold, afraid, or feel strong emotions. (Some readers may experience a paywall.)

Relative to its size, the world's strongest animal is the dung beetle, which can lift over 1,100 times its body weight, though the African bush elephant can lift the most weight among animals.

Heart attack risk jumps to 21 times its norm on the day of a loved one's death

Research published in 2012 suggests that the intense emotional burden of suffering a loved one's death can escalate heart rate, blood pressure, and clot risks—culminating in elevated heart attack risk. The increased heart attack risk remains after that first day, remaining eight times above normal during the first week, and then dropping down over the course of a month. (Some users may encounter a paywall.)

A 'halo' protects drivers

After the 2015 death of driver Jules Bianchi, Formula 1 mandated that all cars include a protective barrier called a “halo.” This video breaks down how that measure saved the life of Romain Grosjean, who survived a horrific crash in 2020 at a race in Bahrain and later credited the halo as the reason for his survival.

Fear (and stress) can be contagious via pheromones secreted by the body

While seeing someone else in a panicked state may induce a stress response, researchers have found stress can be literally contagious—chemicals contained in sweat and other secretions can trigger stress hormone release in others. Theories suggest this feature is an evolutionary adaptation to protect groups from danger.

How trauma gets ‘under the skin’

A study examining the muscle function of older adults who have at least one adverse childhood experience (ACE) suggests that trauma digs itself into muscle cells. Participants who reported childhood trauma were found to have lower maximum levels of cellular energy than people who reported fewer or no ACEs. Such compromised mitochondrial function "doesn't bode well," as it relates to a variety of health and age-related outcomes.

In 2011, a mysterious illness spread around LeRoy, New York

Are you hypnotizable?

What causes some people to genuinely fall under the spell of hypnosis and others not? The technique only appears to work easily on about 10% of people, and a variety of both genetic and psychological factors determines one's susceptibility. Researchers suggest effective hypnosis has more to do with a person's self-control than with external influence—and the technique can have tangible benefits.
