Smoke masks. Eye drops. No outdoor exercise. This is how Californians are trying to cope with wildfires choking the state, but experts say an increase in serious health problems may be almost inevitable for vulnerable residents as the disasters become more commonplace.Research suggests children, the elderly and those with existing health problems are most at risk.Short-term exposure to wildfire smoke can worsen existing asthma and lung disease, leading to emergency room treatment or hospitalization, studies have shown.Increases in doctor visits or hospital treatment for respiratory infections, bronchitis and pneumonia in otherwise healthy people also have been found during and after wildfires.RELATED: Missing-persons list tops 600 in Camp FireSome studies also have found increases in ER visits for heart attacks and strokes in people with existing heart disease on heavy smoke days during previous California wildfires, echoing research on potential risks from urban air pollution.For most healthy people, exposure to wildfire smoke is just an annoyance, causing burning eyes, scratchy throats or chest discomfort that all disappear when the smoke clears.But doctors, scientists and public health officials are concerned that the changing face of wildfires will pose a much broader health hazard."Wildfire season used to be June to late September. Now it seems to be happening all year round. We need to be adapting to that," Dr. Wayne Cascio, a U.S. Environmental Protection Agency cardiologist, said this week.In an overview published earlier this year, Cascio wrote that the increasing frequency of large wildland fires, urban expansion into wooded areas and an aging population are all increasing the number of people at risk for health problems from fires.Wood smoke contains some of the same toxic chemicals as urban air pollution, along with tiny particles of vapor and soot 30 times thinner than a human hair. These can infiltrate the bloodstream, potentially causing inflammation and blood vessel damage even in healthy people, research on urban air pollution has shown. Studies have linked heart attacks and cancer with long-term exposure to air pollution.Whether exposure to wildfire smoke carries the same risks is uncertain, and determining harm from smog versus wildfire smoke can be tricky, especially with wind-swept California wildfires spreading thick smoke hundreds of miles away into smoggy big cities."That is the big question," said Dr. John Balmes, a University of California, San Francisco, professor of medicine who studies air pollution."Very little is known about the long-term effects of wildfire smoke because it's hard to study populations years after a wildfire," Balmes said.Decreased lung function has been found in healthy firefighters during fire season. They tend to recover but federal legislation signed this year will establish a U.S. registry tracking firefighters and potential risks for various cancers, including lung cancer. Some previous studies suggested a risk.Balmes noted that increased lung cancer rates have been found in women in developing countries who spend every day cooking over wood fires.That kind of extreme exposure doesn't typically happen with wildfires, but experts worry about the kinds of health damage that may emerge for firefighters and residents with these blazes occurring so often.Whether that includes more cancer is unknown. "We're concerned about that," Balmes said.Regular folks breathing in all that smoke worry about the risks too.Smoke from the fire that decimated the Northern California city of Paradise darkened skies this week in San Francisco, nearly 200 miles southwest, and the air smelled "like you were camping," said Michael Northover, a contractor.He and his 14-year-old son have first-time sinus infections that Northover blames on the smoke."We're all kind of feeling it," Northover said.The smoke was so thick in San Francisco, the skyline was barely visible from across the Bay. The city's iconic open-air cable cars that are popular with tourists were pulled off the streets Thursday because of the bad air.An Environmental Protection Agency website said air quality in Sacramento was "hazardous" Thursday and San Francisco's was "very unhealthy." Many people walking around the cities wore face masks.Most schools in San Francisco, Sacramento, Oakland and Folsom said they would be closed Friday. At least six universities in Northern California canceled classes Thursday.At Chico State University, 11 miles (18 kilometers) from Paradise, ash fell this week and classes were canceled until after Thanksgiving."It's kind of freaky to see your whole town wearing air masks and trying to get out of smoke," said freshman Mason West, 18. "You can see the particles. Obviously, it's probably not good to be breathing that stuff in."West returned home this week to Santa Rosa, hard hit by last year's wine country fires, only to find it shrouded in smoke from the Paradise fire 100 miles (160 kilometers) away. West's family had to evacuate last year for a week, but their home was spared."It's as bad here as it was in Chico," West said. "It almost feels like you just can't get away from it."Smoke has been so thick in Santa Rosa that researchers postponed a door-to-door survey there for a study of health effects of last year's fire."We didn't feel we could justify our volunteer interns going knocking on doors when all the air quality alerts were saying stay indoors," said Irva Hertz-Picciotto, a public health researcher at the University of California, Davis. The study includes an online survey of households affected by last year's fire, with responses from about 6,000 people so far.Preliminary data show widespread respiratory problems, eye irritations, anxiety, depression and sleep problems around the time of the fire and months later."Conventional thinking is that these effects related to fires are transient. It's not entirely clear that's the case," Hertz-Picciotto said.Researchers also will be analyzing cord blood and placentas collected from a few dozen women who were pregnant during the fire, seeking evidence of stress markers or exposure to smoke chemicals.They hope to continue the study for years, seeking evidence of long-term physical and emotional harms to fire evacuees and their children.Other studies have linked emotional stress in pregnant women to developmental problems in their children and "this was quite a stress," Hertz-Picciotto said.It's a kind of stress that many people need to prepare for as the climate warms and wildfires proliferate, she said."Any of us could wake up tomorrow and lose everything we own," she said. "It's pretty scary."___Follow AP Medical Writer Lindsey Tanner at https://twitter.com/LindseyTanner .

Starbucks bathrooms will be open to anyone who wants to use them, whether they're a paying customer or not, Chairman Howard Schultz said Thursday.Schultz made the announcement following the uproar over the way two black men were treated at a Starbucks in Philadelphia last month.The men asked to use the bathroom, but an employee told them it was only for paying customers. When they then sat in the store without ordering anything, the manager called police, and the men were arrested for trespassing. No charges were filed.Starbucks has since apologized to the men and announced plans for extra racial bias training for its employees."We don't want to become a public bathroom, but we're going to make the right decision 100% of the time and give people the key, because we don't want anyone at Starbucks to feel as if we are not giving access to you to the bathroom because you are less than. We want you to be more than," Schultz said during a talk at the Atlantic Council in Washington.Schultz said the company currently has a "loose" policy of only allowing paying customers to use the bathroom, with the decision ultimately left to the store manager.But he said the policy and the decision by the Philadelphia store manager last month were "absolutely wrong in every way.""It's the company that's responsible," he added.Starbucks didn't immediately respond to a request for further details about the change announced by Schultz.Starbucks has said it will close its 8,000 company-owned stores in the United States on the afternoon of May 29 to educate employees about racial bias.The training for about 175,000 workers "will be the largest kind of training of its kind on perhaps one of the most systemic subjects and issues facing our country," Schultz said.  1779

Some members of a large group of migrants who tried to rush the US border from Mexico, prompting the closure of a major border crossing in San Diego, will be deported to their home countries, according to Mexican authorities.About 500 migrants on the Mexican side of the border overwhelmed police blockades near the San Ysidro Port of Entry Sunday afternoon, two journalists at the scene in Tijuana told CNN.Tijuana police arrested 39 people in connection with the attempt to cross the border illegally, the agency said in a statement on Facebook.It said they would be reported to Mexican immigration authorities.Mexico's Interior Ministry earlier said those identified as having tried to cross would be processed for deportation to their home countries. 762

SEOUL, South Korea (AP) — Police say the body of the missing mayor of South Korea's capital, Seoul, has been found. They say Park Won-soon’s body was located in hills in northern Seoul early Friday, more than seven hours after they launched a massive search for him. Park’s daughter had called police on Thursday afternoon to report him missing, saying he had given her a “will-like” message before leaving home. Police say the daughter didn’t explain the contents of the message.News reports say one of Park’s secretaries had lodged a complaint with police on Wednesday night over alleged sexual harassment.An activist and human rights lawyer, Park became the city’s first mayor to be voted into a third term last June. He was also a potential presidential candidate in 2022 polls. 790
