Dutch extreme athlete Wim Hof is known for chilly feats like the world's longest ice bath and climbing Mount Kilimanjaro in just a pair of shorts. (Hof is the subject of the recent New York Times bestseller "What Doesn't Kill Us: How Freezing Water, Extreme Altitude, and Environmental Conditioning Will Renew Our Lost Evolutionary Strength" by Scott Carney.) Now, researchers from Wayne State University’s School of Medicine recently used an MRI scanner to explore the science behind Hof's dangerous stunts. From Smithsonian:

Hof attributes his success to what he has dubbed the Wim Hof Method, a type of conditioning that involves a series of breathing exercises he says anyone can replicate. Rather than by luck or accident, Hof says he learned his technique by trial and error while going out into nature: “I had to find the interconnection of my brain together with my physiology...."

Musik found that, when exposed to cold, Hof activates a part of the brain that releases opioids and cannabinoids into the body. These components can inhibit the signals responsible for telling your body you are feeling pain or cold, and trigger the release of dopamine and serotonin. The result, Musik says, is a kind of euphoric effect on the body that lasts for several minutes.

“Your brain has the power to modify your pain perception,” he says, adding that this mechanism is particularly important for human survival. Pain, and the feeling of cold, are basically your body’s way of telling you something is wrong.

Members of the San Francisco Giants are using transcranial direct current stimulation (tDCS) in an effort to improve their performance on the field. According to SF Giants sports scientist Geoff Head (real name!), "some big-name players" are using the Halo Sport device, resembling Beats headphones, to deliver a small amount of current to the wearer's motor cortex. From KQED:

Head decided to try the headset, called Halo Sport, during spring training last year—he gave them to some minor leaguers to wear as they sprinted 20-yard dashes. After two weeks, Head analyzed the results and found that the players who wore the equipment had shaved off a few one-hundredths of a second compared to a control group....

Even though a lot of the data is conflicting, the most positive results do support using tDCS to improve motor control. Hence the slew of startups targeting athletes.

The Giants’ Head says even a tiny advantage can help win games at the major league level. An improvement of two-hundredths of a second can be “the difference between safe and out sometimes,” he says.
