California braces for early, sharper flu season as virus mutation outpaces vaccine, experts say

California could see an early start to the annual flu season, as a combination of low vaccination rates and late mutations to the virus may leave the state particularly exposed to transmission, health experts say.

Already, there are warning signs. Los Angeles County recently reported its first flu death of the season, and other nations are reporting record-breaking or powerful, earlier-than-expected flu seasons.

Typically, flu picks up right after Christmas and into the New Year, but Dr. Elizabeth Hudson, regional physician chief of infectious diseases at Kaiser Permanente Southern California, said she expects increases in viral activity perhaps over the next two to three weeks.

“We’re expecting an early and likely sharp start to the flu season,” Hudson said.

Last year’s flu season was the worst California had seen in years, and it’s not usual for there to be back-to-back bad flu seasons. But a combination of a decline in flu vaccination rates and a “souped-up mutant” is particularly concerning this year, according to Dr. Peter Chin-Hong, an infectious diseases expert at UC San Francisco.

“That may translate into more people getting infected. And as more people get infected, a proportion of them will go to the hospital,” Chin-Hong said.

The timing of this new flu subvariant — called H3N2 subclade K — is particularly problematic. It emerged toward the end of the summer, long after health officials had already determined how to formulate this fall’s flu vaccine, a decision that had to be made in February.

H3N2 subclade K seems to be starting to dominate in Japan and Britain, Hudson said.

“It looks like a bit of a mismatch between the seasonal flu vaccine strains” and the new subvariant, Hudson said.

It remains unclear whether subclade K will reduce the effectiveness of this year’s flu shot.

In California and the rest of the U.S., “things are quiet, but I think it’s just a calm before the storm,” Chin-Hong said. “From what we see in the U.K. and Japan, a lot more people are getting flu earlier.”

Chin-Hong noted that subclade K is not that much different than the strains this year’s flu vaccines were designed against. And he noted data recently released in Britain that showed this season’s vaccines were still effective against hospitalization.

According to the British government, vaccinated children were 70% to 75% less likely to need hospital care, and adults were 30% to 40% less likely. Flu vaccine effectiveness is typically between 30% to 60%, and tends to be more effective in younger people, the British government said.

Even if there is some degree of mismatch between the vaccine and circulating strains, “the flu vaccine still provides protection against severe illness, including hospitalizations,” according to the Los Angeles County Department of Public Health.

“Public Health strongly encourages everyone who has not received the flu vaccine yet this year to receive it now, especially before gathering with loved ones during the holidays,” the department said in a statement.

But “while mismatched vaccines may still provide protection, enhanced genetic, antigenic and epidemiological … monitoring are warranted to inform risk assessment and response,” according to scientists writing in the Journal of the Assn. of Medical Microbiology and Infectious Diseases Canada.

Because the vaccine is not a perfect match for the latest mutated flu strain, Chin-Hong said getting antiviral medication like Tamiflu to infected patients may be especially important this year, even for those who are vaccinated. That’s especially true for the most vulnerable, which include the very young and very old.

“But that means you need to get diagnosed earlier,” Chin-Hong said. Drugs like Tamiflu work best when started within one to two days after flu symptoms begin, the U.S. Centers for Disease Control and Prevention says.

There are now at-home flu testing kits that are widely available for sale for people who are showing signs of illness.

Also worrying is how the flu has surged in other countries.

Australia’s flu season came earlier this year and was more severe than usual. The Royal Australian College of General Practitioners said that nation saw a record flu season, with more than 410,000 lab-confirmed cases, up from the prior all-time high of 365,000 that were reported last year.

“This is not a record we want to be breaking,” Dr. Michael Wright, president of the physician’s group, said.

Hudson noted Australia’s flu season was “particularly hard on children” this year.

L.A. County health officials cautioned that Australia’s experience isn’t a solid predictor of what happens locally.

“It is difficult to predict what will happen in the United States and Los Angeles, as the severity of the flu season depends on multiple factors including circulating strains, pre-existing immunity, vaccine uptake, and the overall health of the population,” the L.A. County Department of Public Health said.

The new strain has also thrown a wrench in things. As Australia’s flu season was ending, “this new mutation came up, which kind of ignited flu in Japan and the U.K., and other parts of Europe and Asia,” Chin-Hong said.

On Friday, Japan reportedly issued a national alert with flu cases surging and hospitalizations increasing, especially among children and the elderly, accompanied by a sharp rise in school and class closures. The Japanese newspaper Asahi Shimbun said children ages 1 through 9 and adults 80 and up were among the hardest-hit groups.

Taiwanese health officials warned of the possibility of a second peak in flu this year, according to the Central News Agency. There was already a peak in late September and early October — a month earlier than normal — and officials are warning about an uptick in flu cases starting in December and then peaking around the Lunar New Year on Feb. 17.

Taiwanese officials said 95% of patients with severe flu symptoms had not been recently vaccinated.

British health officials this month issued a “flu jab SOS,” as an early wave struck the nation. Flu cases are “already triple what they were this time last year,” Public Health Minister Ashley Dalton said in a statement.

In England, outside of pandemic years, this fall marked the earliest start to the flu season since 2003-04, scientists said in the journal Eurosurveillance.

“We have to brace ourselves for another year of more cases of flu,” Chin-Hong said.

One major concern has been declining flu vaccination rates — a trend seen in both Australia and the United States.

In Australia, only 25.7% of children age 6 months to 5 years were vaccinated against flu in 2025, the lowest rate since 2021. Among seniors age 65 and up, 60.5% were vaccinated, the lowest rate since 2020.

Australian health officials are promoting free flu vaccinations for children that don’t require an injection, but are administered by nasal spray.

“We must boost vaccination rates,” Wright said.

In the U.S., officials recommend the annual flu vaccine for everyone age 6 months and up. Those age 65 and up are eligible for a higher-dose version, and kids and adults between age 2 and age 49 are eligible to get vaccinated via the FluMist nasal spray, rather than a needle injection.

Officials this year began allowing people to order FluMist to be mailed to them at home.

Besides getting vaccinated, other ways to protect yourself against the flu include washing your hands frequently, avoiding sick people and wearing a mask in higher-risk indoor settings, such as while in the airport and on a plane.

Healthy high-risk people, such as older individuals, can be prescribed antiviral drugs like Tamiflu if another household member has the flu, Chin-Hong said.

Doctors are especially concerned about babies, toddlers and young children up to age 5.

“Those are the kids that are the most vulnerable if they get any kind of a respiratory illness. It can really go badly for them, and they can end up extraordinarily ill,” Hudson said.

In the United States, just 49.2% of children had gotten a flu shot as of late April, lower than the 53.4% who had done so at the same point the previous season, according to preliminary national survey results. Both figures are well below the final flu vaccination rate for eligible children during the 2019-20 season, which was 63.7%.

Among adults, 46.7% had gotten their flu shot as of late April, slightly down from the 47.4% at the same point last season, according to the preliminary survey results, which are the most recent data available.

“Before the COVID-19 pandemic, flu vaccination coverage had been slowly increasing; downturns in coverage occurred during and after the pandemic. Flu vaccination levels have not rebounded to pre-pandemic levels,” according to the CDC.

The disparaging of vaccinations by federal health officials, led by the vaccine-skeptic secretary of the U.S. Department of Health and Human Services, Robert F. Kennedy Jr., has not helped improve immunization rates, health experts say. Kennedy told the New York Times on Thursday that he personally directed the CDC to change its website to abandon its position that vaccines do not cause autism.

Mainstream health experts and former CDC officials denounced the change. “Extensive scientific evidence shows vaccines do not cause autism,” wrote Daniel Jernigan, Demetre Daskalakis and Debra Houry, all former top officials at the CDC, in an op-ed to MS NOW.

“CDC has been updated to cause chaos without scientific basis. Do not trust this agency,” Daskalakis, former director of the CDC’s National Center for Immunization and Respiratory Diseases, added on social media. “This is a national embarrassment.”

State health officials from California, Washington, Oregon and Hawaii on Friday called the new claims on the CDC website inaccurate and said there are decades of “high quality evidence that vaccines are not linked to autism.”

“Over 40 high-quality studies involving more than 5.6 million children have found no link between any routine childhood vaccine and autism,” the L.A. County Department of Public Health said Friday. “The increase in autism diagnoses reflects improved screening, broader diagnostic criteria, and greater awareness, not a link to vaccines.”

Hudson said it’s important to get evidence-based information on the flu vaccines.

“Vaccines save lives. The flu vaccine in particular saves lives,” Hudson said.

At 89, he’s heard six decades of L.A.’s secrets and is ready to talk about what he’s learned

At 89, he’s heard six decades of L.A.’s secrets and is ready to talk about what he’s learned

Dr. Arnold Gilberg’s sunny consultation room sits just off Wilshire Boulevard. Natural light spills onto a wooden floor, his houndstooth-upholstered armchair, the low-slung couch draped with a colorful Guatemalan blanket.

The Beverly Hills psychiatrist has been seeing patients for more than 60 years, both in rooms like this and at Cedars-Sinai Medical Center, where he has been an attending physician since the 1960s.

He treats wildly famous celebrities and people with no fame at all. He sees patients without much money and some who could probably buy his whole office building and not miss the cash.

Gilberg, 89, has treated enough people in Hollywood, and advised so many directors and actors on character psychology, that his likeness shows up in films the way people float through one another’s dreams.

The Nancy Meyers film “It’s Complicated” briefly features a psychiatrist character with an Airedale terrier — a doppelganger of Belle, Gilberg’s dog who sat in on sessions until her death in 2018, looking back and forth between doctor and patient like a Wimbledon spectator.

“If you were making a movie, he would be central casting for a Philip Roth‑esque kind of psychiatrist,” said John Burnham, a longtime Hollywood talent agent who was Gilberg’s patient for decades starting in his 20s. “He’s always curious and interested. He gave good advice.”

Since Gilberg opened his practice in 1965, psychiatry and psychotherapy have gone from highly stigmatized secrets to something people acknowledge in award show acceptance speeches. His longtime prescriptions of fresh food, sunshine, regular exercise and meditation are now widely accepted building blocks of health, and are no longer the sole province of ditzy L.A. hippies.

He’s watched people, himself included, grow wiser and more accepting of the many ways there are to live. He’s also watched people grow lonelier and more rigid in their political beliefs.

On a recent afternoon, Gilbert sat for a conversation with The Times at the glass-topped desk in his consultation room, framed by a wall full of degrees. At his elbow was a stack of copies of his first book, “The Myth of Aging: A Prescription for Emotional and Physical Well-Being,” which comes out Tuesday.

In just more than 200 pages, the book contains everything Gilberg wishes he could tell the many people who will never make it into his office. After a lifetime of listening, the doctor is ready to talk.

Gilberg moved to Los Angeles in 1961 for an internship at what is now Los Angeles General Medical Center. He did his residency at Mount Sinai Hospital (later Cedars-Sinai) with the famed Hungarian American psychoanalyst Dr. Franz Alexander.

Among his fellow disciples of Sigmund Freud, Alexander was a bit of an outlier. He balked at Freud’s insistence that patients needed years of near-daily sessions on an analyst’s couch, arguing that an hour or two a week in a comfortable chair could do just as much good. He believed patients’ psychological problems stemmed more often from difficulties in their current personal relationships than from dark twists in their sexual development.

Not all of Alexander’s theories have aged well, Gilberg said — repressed emotions do not cause asthma, to name one since-debunked idea. But Gilberg is the last living person to have trained with Alexander directly and has retained some of his mentor’s willingness to go against the herd.

If you walk into Gilberg’s office demanding an antidepressant prescription, for example, he will suggest you go elsewhere. Psychiatric medication is appropriate for some mental conditions, he said, but he prefers that patients first try to fix any depressing situations in their lives.

He has counseled patients to care for their bodies long before “wellness” was a cultural buzzword. It’s not that he forces them to adopt regimens of exercise and healthy eating, exactly, but if they don’t, they’re going to hear about it.

“They know how I feel about all this stuff,” he said.

He tells many new patients to start with a 10-session limit. If they haven’t made any progress after 10 visits, he reasons, there’s a good chance he’s not the right doctor for them. If he is, he’ll see them as long as they need.

One patient first came to see him at 19 and returned regularly until her death a few years ago at the age of 79.

“He’s had patients that he’s taken care of over the span, and families that have come back to him over time,” said Dr. Itai Danovitch, who chairs the psychiatry department at Cedars-Sinai. “It’s one of the benefits of being an incredibly thoughtful clinician.”

Not long after opening his private practice in 1965, Gilberg was contacted by a prominent Beverly Hills couple seeking care for their son. The treatment went well, Gilberg said, and the satisfied family passed his name to several well-connected friends.

As a result, over the years his practice has included many names you’d recognize right away (no, he will not tell you who) alongside people who live quite regular lives.

They all have the same concerns, Gilberg says: Their relationships. Their children. Their purpose in life and their place in the world. Whatever you achieve in life, it appears, your worries remain largely the same.

When it’s appropriate, Gilberg is willing to share that his own life has had bumps and detours.

He was born in Chicago in 1936, the middle of three boys. His mother was a homemaker and his father worked in scrap metal. Money was always tight. Gilberg spent a lot of time with his paternal grandparents, who lived nearby with their adult daughter, Belle.

The house was a formative place for Gilberg. He was especially close to his grandfather — a rabbi in Poland who built a successful career in waste management after immigrating to the U.S. — and to his Aunt Belle.

Disabled after a childhood accident, Belle spent most of her time indoors, radiating a sadness that even at the age of 4 made Gilberg worry for her safety.

“It’s one of the things that brought me into medicine, and then ultimately psychiatry,” Gilberg said. “I felt very, very close to her.”

He and his first wife raised two children in Beverly Hills. Jay Gilberg is now a real estate developer and Dr. Susanne Gilberg-Lenz is an obstetrician-gynecologist (and the other half of the only father-daughter pair of physicians at Cedars-Sinai).

The marriage ended when he was in his 40s, and though the split was painful, he said, it helped him better understand the kind of losses his patients experienced.

He found love again in his 70s with Gloria Lushing-Gilberg. The couple share 16 grandchildren and seven great-grandchildren. They married four years ago, after nearly two decades together.

“As a psychoanalyst or psychiatrist ages, we have the ability, through our own life experiences, to be more understanding and more aware,” he said.

It’s part of what keeps him going. Though he has reduced his hours considerably, he isn’t ready to retire. He has stayed as active as he advises his patients to be, both personally (he was ordained as a rabbi several years ago) and professionally.

For all the strides society has made during the course of his career toward acceptance and inclusivity, he also sees that patients are lonelier than they used to be. They spend less time with friends and family, have a harder time finding partners.

We’re isolated and suffering for it, he said, as individuals and as a society. People still need care.

Unlike a lot of titles on the self-help shelves, Gilberg’s book promises no sly little hack to happiness, no “you’ve-been-thinking-about-this-all-wrong” twist.

His prescriptions run along deceptively simple lines: Care for your health. Say thank you. Choose to let go of harmless slights and petty conflicts. Find people you belong with, and stop holding yourself and others to impossibly high standards.

“People have the capacity to self-heal, and I have become a firm believer in that. Not everyone needs to be in therapy for 10 years to figure it out,” he said. “A lot of this is inside yourself. You have an opportunity to overcome the things and obstacles that are in you, and you can do it.”

So what is “it”? What does it mean to live a good life?

Gilberg considered the question, hands clasped beneath his chin, the traffic outside humming expectantly.

“It means that the person has been able to look at themselves,” he said, “and feel somewhat happy about their existence.”

Advertisement

The best any of us can hope for is to be … somewhat happy?

Correct, Gilberg said. “A somewhat happy existence, off and on, which is normal. And hopefully, if the person wants to pursue that, some kind of a personal relationship.”

As it turns out, there is no housing in happiness. You can visit, but nobody really lives there. The happiest people know that. They live in OK neighborhoods that are not perfect but could be worse. They try to be nice to the neighbors. The house is a mess a lot of the time. They still let people in.

Somewhat happy, sometimes, with someone else to talk to.

It is that simple. It is that hard.

FEMA to pay for lead testing at 100 homes destroyed in Eaton fire, after months of saying it was unnecessary

FEMA to pay for lead testing at 100 homes destroyed in Eaton fire, after months of saying it was unnecessary

In a remarkable reversal, the U.S. Environmental Protection Agency is expected to announce that the Federal Emergency Management Agency will pay for soil testing for lead at 100 homes that were destroyed by the Eaton fire and cleaned up by federal disaster workers.

The forthcoming announcement would mark an about-face for FEMA officials, who repeatedly resisted calls to test properties for toxic substances after federal contractors finished removing fire debris. The new testing initiative follows reporting by The Times that workers repeatedly violated cleanup protocols, possibly leaving fire contaminants behind or moving them into unwanted areas, according to federal reports.

The EPA plan, presented to a small group of environmental experts and community members on Jan. 5, said the agency would randomly select 100 sites from the 5,600 homes that had burned down in the Eaton fire and where the U.S. Army Corps of Engineers oversaw the removal of ash, debris and a layer of soil. The soil samples would be collected near the surface and about 6 inches below ground.

Sampling is expected to begin next week, with test results published in April.

During the Jan. 5 presentation, some attendees questioned whether the testing would meaningfully assess whether properties are safe to rebuild on.

Local environmental health advocates worry the EPA testing is designed only to justify FEMA’s decision not to undertake comprehensive soil testing, instead of providing real relief to their communities.

“The EPA’s plan to run a study that retroactively validates a limited soil-removal response after the L.A. Fires is deeply concerning, especially when there is ample independent data indicating contamination persists beyond what was addressed,” said Jane Lawton Potelle, executive director of the grassroots environmental health group Eaton Fire Residents United, in a statement. “The hard truth is that meaningful contamination recovery still has not been funded or delivered by the federal government or the State of California.“

The EPA’s proposed approach is narrower than soil-testing efforts for previous fires in California. Although lead is one of the most common and dangerous contaminants left behind after fires, federal and state disaster officials have traditionally tested soil for 17 toxic metals, including cancer-causing arsenic and toxic mercury.

The EPA plan also calls for taking soil from 30 different parts of each cleanup area and combining them into one singular representative sample. That method doesn’t align with California’s soil-testing policy and could obscure “hot spots” of contamination on a property.

“If you don’t want to find a high number [of contaminants], you take a lot of samples and you mix them together,” said Andrew Whelton, a Purdue University professor who researches natural disasters.

“Based on the experimental design of [the EPA plan], I do not understand the purpose of what they’re doing, because it is not meant to determine if the properties are safe or not,” Whelton added.

For nearly a year, FEMA refused to pay for soil testing, insisting it was time-consuming, costly and unnecessary. FEMA, along with the U.S. Army Corps of Engineers, maintained that removing ash, debris and a layer of soil would be enough to rid properties of toxic substances.

Federal officials insisted any lingering contamination on properties likely predated the fire and was caused by decades’ worth of pollution from cars and industry.

Daisy Rosas Vargas, a chemist and soil scientist with SoilWise, a local soil health and landscaping consulting business, was skeptical that the EPA’s testing, now a year after the fire, could meaningfully distinguish fire-related contamination supposedly on the surface from any legacy contamination deeper underground.

Historic fire data showed about 20% of properties still contain toxic substances above California’s benchmarks for residential properties.

What’s more, a trove of federal reports obtained by The Times revealed federal contractors repeatedly deviated from their cleanup plans for the January 2025 fires, possibly leaving dozens of properties with toxic ash and debris.

FEMA hired inspectors to observe the cleanup process and document any issues; the resulting reports say, in some cases, that workers sprayed contaminated pool water on properties, walked through recently clean properties with dirty boot covers and mixed clean and contaminated soil by using improper equipment.

In one of the most egregious violations, an inspector noted that an official with Environmental Chemical Corp., the primary contractor hired to oversee debris removal in the Eaton and Palisades fires, ordered a work crew to dump ash and debris onto a neighboring property.

A spokesperson for the Army Corps said “all deficiencies logged by” federal inspectors were “addressed and corrected.”

“Our robust quality assurance program was staffed with hundreds of quality assurance inspectors and engineers,” the spokesperson said. “The deficiencies that were identified in the article were corrected immediately or before Final Sign Off.”

The agency did not provide any details about how workers resolved the alleged illegal dumping, or any other deficiencies.

Numerous soil-testing efforts had already found contamination above state standards. Los Angeles Times journalists launched a soil-testing project and published the first evidence that fire-destroyed homes in the Eaton fire still contained elevated levels of soil contamination, even after federal cleanup workers finished removing debris.

Los Angeles County and UCLA-led soil testing initiatives also found elevated levels of contaminants at Army Corps-cleared properties.

EPA officials said the agency would share soil-testing results with property owners, in addition to Los Angeles County and state agencies. However, they did not say whether they intended to remove another layer of soil if lead levels exceed state and federal standards.

After hearing about the EPA plan, Jessica Handy, one of the co-founders of the Dena Soil Project, a grassroots coalition focused on providing soil testing and other aid to those impacted by the Eaton fire, questioned the value of such testing without a commitment to cleanup. “If it does show that there’s still contaminants, what is the solution?” asked Handy, a Pasadena native. “We’re at risk of losing more community members because they’re afraid that they’re going to expose themselves, their families, their pets, their elders.”

U.S. Rep. Judy Chu (D-Monterey Park), who previously called on federal disaster agencies to provide comprehensive soil testing for fire victims, sent an email to her constituents last week saying she is “seeking assurance that they take action if the results of their testing find contamination.”

The Army Corps and its contractors initially aimed to demobilize by Jan. 8, 2026, the one-year anniversary of the fires, but federal cleanup efforts finished much earlier than expected. Federal cleanup workers removed fire debris from the final home enrolled in the federal program in Los Angeles’ Pacific Palisades in early September.

Federal and state officials hailed the Army Corps efforts as the fastest major cleanup in modern American history.

As of Monday afternoon, FEMA and the EPA have not responded to questions sent by The Times regarding specifics of the testing plan.

49ers coach Kyle Shanahan shows performance-enhancing smelling salts aren’t just for players

49ers coach Kyle Shanahan shows performance-enhancing smelling salts aren’t just for players

Football leans on tradition, providing convenient cover for the NFL’s lenient stance on smelling salts, ammonia crystals that players believe enhance performance when inhaled.

Does the olfactory exhilaration also enhance play-calling, amplifying one’s grasp of X’s and O’s?

Kyle Shanahan apparently believes so.

The San Francisco 49ers coach was caught by a Fox television camera moments before a playoff game Sunday against the Philadelphia Eagles taking several whiffs from a small packet before handing it to an assistant.

Earlier this season, the San Francisco Chronicle reported that 49ers players created a system to make sure everyone has immediate access to smelling salts during games. General manager John Lynch and Shanahan are users, according to the story, which stated that Shanahan “isn’t opposed to the occasional whiff.”

Is the NFL OK with this? The answer is a qualified yes.

Ahead of the 2025 season, the league’s head, neck and spine committee recommended that teams end the longtime practice of providing smelling salts to players. The decision was prompted by a U.S. Food and Drug Administration warning about the potential side effects of inhaling ammonia, which include lung damage and masking signs of a concussion.

Players all but panicked. George Kittle, the 49ers All-Pro tight end, jumped on an NFL Network broadcast to proclaim that smelling salts were crucial to his performance.

“I’m a regular user of smelling salts, taking them for a boost of energy before every offensive drive,” he said. “We have got to figure out a middle ground here, guys. Somebody help me out.”

The NFL came to his rescue, saying smelling salts — also known as ammonia inhalants, or AIs — were not banned. Teams could no longer provide them, but players could bring their own. It’s a compromise that may or may not pass the smell test. Either way, it’s not just the 49ers using them.

An ESPN Magazine piece in 2017 reported that “just a few minutes into the game, the Cowboys have discarded so many capsules that the area in front of their bench looks like the floor of a kid’s bedroom after trick-or-treating.”

Bottom line, legions of NFL players believe AIs enhance performance. They do so by irritating the linings of the nose and lungs, triggering a reflex that increases breathing rate and blood flow, fostering alertness.

Their effectiveness was discovered long before football was invented. Craft beer drinkers know Pliny the Elder as the inspiration for his namesake double IPA. The noted Roman naturalist and historian was indeed an early expert in fermentation, yet he also wrote about “sal ammoniac” — yes, smelling salts — in his encyclopedic work “Natural History,” published in 79 A.D.

Their popularity spread through Europe until, in Victorian tradition, they were used to rouse ladies after fainting spells. Later they were used in battle, with British medics supplying World War II soldiers with a whiff of the substance that doctors say triggers the body’s “fight-or-flight” response.

These days, the Federal Aviation Administration requires that U.S. airlines carry smelling salts onboard in case a pilot needs to be awakened after fainting. Blocking and tackling on a flight, however, remains strictly forbidden.

The NFL’s middling position isn’t curious. Experts say it’s an attempt to reduce liability in case of concussions or other medical complications. But it is their constant use that concerns doctors.

“The use of smelling salts in sports is definitely not their intended use,” Dr. Laura Boxley, a neuropsychologist at Ohio State’s Wexner Medical Center, told NPR. “What’s happening with some athletes is they’re using them with much higher frequency than their intended use.”

Given the relative safety of the sidelines, Shanahan isn’t in danger of a brain-rattling concussion. Shortly after the NFL ceased supplying AIs, he was asked by a reporter whether he had concerns about their prevalence.

“I mean, I don’t,” Shanahan replied with a grin. “If someone gives me one, I’ll take a smell of the salt. I’m not too worried about it. I like to take one to wake myself up and lock myself in.”
