Cold reality cools hot hype of cryotherapy

Kerry Lauerman | Washington Post

A new ice age is here. And it’s making amazing promises of pain-free joints and sculpted abs.

Cryotherapy – a freezing treatment turned piping-hot health trend – is being hyped by spas across the country, many of which have sprung up within the last year.

Among them, NYC Cryo in New York promises that cryotherapy leads to "quicker surgical recovery time." Thrive CryoStudio in Rockville, Maryland, claims it "alleviates symptoms from joint disorders, rheumatoid diseases, fibromyalgia, psoriasis and migraines." Atlanta’s Cryo Elite Therapy said it "has been proven to improve peak levels of performance." Omaha’s Ice Out CryoSpa boasts "alleviation of depression, anxiety, fatigue, insomnia." CryoSF in San Francisco says the treatment "helps increase testosterone in men" and "reduces signs of aging, increases collagen production, improves skin condition and reduces cellulite."

The problem: There’s no solid scientific evidence to back any of it up. And the Federal Drug Administration is warning spas to stop making such claims.

There’s actually very little research on cryotherapy at all. "The evidence is lacking for me to say yes, it’s effective, or no, it’s not effective," says Joseph Costello, a lecturer in exercise physiology at the University of Portsmouth in England, who has written a much-cited review of all the available research on whole body cryotherapy last year.

That isn’t stopping untold thousands from lining up every week to follow the likes of LeBron James, Tony Robbins and sundry celebrities and "Real Housewives" into cylindrical cryotherapy chambers, where they get blasted from the neck down with abominably cold air.

What does cryotherapy do, exactly? Advocates like to say that the cold air forces blood to your core, tricking the body into thinking it’s experiencing hypothermia. From there, the claims get a bit fuzzy. Whole body cryotherapy believers say it acts as a super-charged ice bath, allowing muscles and tendons to more quickly recover from heavy training or pain, reducing inflammation. And many just claim, in the most unscientific of terms, that they feel energized by the treatment.

Following the oversize claims made by some cryotherapy providers – and after the death of one person in a cryotherapy chamber last year – the FDA issued a strongly worded warning against whole body cryotherapy in July. "(C)onsumers may incorrectly believe that the FDA has cleared or approved (whole body cryotherapy) de­vices as safe and effective to treat medical conditions," Aron Yustein, a medical officer in the FDA’s Center for Devices and Radiological Health, said in the FDA release. "That is not the case."

The FDA recently released letters it sent to two California cryotherapy businesses advising them that the health claims they were making about cryotherapy "may be considered false and misleading." Deborah Kotz, an FDA spokeswoman, said that, beyond warning letters and recalls, the FDA can take "further enforcement action to protect public health including conducting and coordinating criminal investigations."

The allure of cold therapies has been around for a long time. The Greeks promoted cold baths as a healthy tonic; the Romans celebrated in their Frigidariums. Charles Darwin swore by a daily cold shower. But whole body cryotherapy was specifically developed in 1978 by a physician, Toshima Yamauchi, as an experimental way to treat rheumatoid arthritis. By the 1990s, it began to become popular in various European spas as an alternative treatment for chronic pain.

It started drawing public attention here in 2011, when U.S. athletes followed the lead of UK soccer teams and embraced it as a restorative, post-competition therapy. The Dallas Mavericks regularly frequented cryotherapy chambers during their run to their first NBA championship and – notoriously – U.S. sprinter Justin Gatlin went to the world championships complaining of frostbitten feet caused, he claimed, by wearing damp socks in a cryotherapy chamber.

Cryotherapy spread to the celebrity set, with Jennifer Aniston, Daniel Craig and Jessica Alba reportedly booking appointments. Tony Robbins told fellow self-help and lifestyle guru Timothy Ferriss on his podcast that cryotherapy’s effects on him were "mind-boggling," gave him "an explosion of endorphins" and said he’d purchased a unit for his home and for his mother-in-law, who suffered from arthritis.

All that Hollywood sizzle slowed last year after 24-year-old Chelsea Ake-Salvacion was found dead in a cryotherapy unit in the Las Vegas area spa where she worked.

An autopsy later ruled that she had suffocated. She might have lost consciousness when she ducked her head down into the unit, possibly to retrieve her cellphone, and succumbed to the liquid-nitrogen-cooled air.

"If it lets you drop your head 6 inches and you die, something is wrong there," said Richard Harris, a lawyer representing Ake-Salvacion’s family. He said he was "on the verge" of filing a suit against the manufacturer, distributor and spa. Ake-Salvacion had closed the shop and was alone when she died, and Harris believes the units should have safety features preventing them from being operated alone (which some now do).

But if that tragedy cooled cryotherapy’s hype, it didn’t last.

One of the major US distributors of cryotherapy units, Impact Cryotherapy from Atlanta, says sales have continued to soar. Impact announced in July it had sales of 200 units since the company launched in June 2014, but "we’ve probably bumped over 250 now," he said this month. Another major distributor, CryoUSA out of Dallas, lists more than 200 places it has sold cryotherapy units in the past five years.

I asked the University of Portsmouth’s Costello, who had said he tried out the treatment multiple times, how he responds to it. "It makes me cold," he said.

But Kenneth Knight, a retired professor of exercise sciences at Brigham Young, says cold is good. Knight studied the impact of cryotherapy for more than 40 years, since he wrote his doctorate on the subject. ("He literally wrote the book on cryotherapy," Costello says.)

His basic belief is that when we injure ourselves, our bodies tend to overreact with pain. "My premise is that the cold knocks out pain, and lets a person start exercising," he says.

For Matt Bellina, a 33-year-old father of two boys who was diagnosed with ALS five years ago, whole body cryotherapy has become a daily – sometimes twice daily – ritual for the past six months at the Newtown Athletic Club, in Newton, Pennsylvania.

ALS, a nervous system disorder that destroys nerve cells in the brain and spinal column, slowly attacks a patient’s ability to use and control muscles. He says that cryotherapy has been "by far the most effective treatment."

"It’s definitely not a cure, but it’s definitely helping. I’m in a lot less pain, I’m sleeping better at night, I have a lot more energy," Bellina said.

The ALS makes keeping up with his two sons, ages 3 and 5, a challenge – "My hands kind of suck, and I trip a lot." – and early this year, his condition seemed to be getting rapidly worse. "I had been in a downhill slide."

But he believes the cryotherapy has helped "level things out." And he says his doctor cautiously endorses his sessions – "if I think it’s helping."
