America's growing elderly population endangered by rising heat, wildfires

News Feed
Saturday, July 20, 2024

The rising frequency and intensity of extreme heat events are exacerbating the health and safety concerns of America's older population — an already vulnerable community, and one that's growing fast. "We're seeing increasing heat and increasing extremes of heat," said Ian Neel, a geriatrician and an associate professor at the University of California San Diego School of Medicine, at a recent webinar.  "But we're also seeing increasing frequency of older adults, and older adults are one of the more at-risk populations for heat related injuries," he added. The population of Americans 65 or older ballooned from roughly 40 million to 56 million between 2010 and 2020, and it is projected to grow by another 17 million by the end of this decade. At the same time, temperatures are swelling around the world, shattering heat records and contributing to an increase in wildfires. Tarik Benmarhnia, an associate professor in climate change epidemiology at UC San Diego's Scripps Institution of Oceanography, described extreme heat as "a huge, silent and sneaky killer." While prevailing estimates today directly link between 6,000 and 7,000 American deaths to heat each year, Benmarhnia challenged that figure as "only the tip of the iceberg." When considering how extreme heat can also trigger complications in an aging population living with chronic diseases, he said that this number could be as high as 12,000 to 20,000 annual deaths. Neel, who works predominantly with older adults experiencing advanced dementia, characterized heat as "one of the major things that we see as a huge detriment on patients' health." "Invariably, what we see every summer, more and more frequently, is an increasing incidence of older adults coming in with falls," Neel said. Those falls are often "related to dehydration, related to heat exhaustion, heat stroke, as well as serious sequelae of heat stroke," he added, using the medical term for a condition that results from a previous injury or disease. Zooming in on his own region, Neel discussed the wide range of communities throughout San Diego County — noting that further east in the high desert, there is typically a smaller incidence of central air conditioning in homes. As such, he explained that "having access to community centers that may have central air if you can't get it, ways to try to mitigate cooling," is an essential step toward alleviating the threats extreme heat poses on older Americans. "It's easy to say, 'Oh, buy central air,' but people are struggling financially everywhere, so it's just not an easy fix," Neel acknowledged. "One of the biggest and most important things is to make sure that you have access and that you are drinking water and staying hydrated," he said. Another unique issue challenging geriatricians like Neel is the fact that they can "try to educate a patient with dementia on how to keep safe in the heat, but they're not going to remember," the physician added. Neel therefore called for increased awareness on a societal level — encouraging relatives and neighbors to look out for older loved ones who could be prone to heat stroke. For example, he recommended that friends and family schedule check-ins with these individuals to ensure that they aren't wandering around in the backyard. Neel recalled a recent instance in which he saw a dementia patient with third degree burns all over her body. For those people who lack air conditioning and who tend to be alone during daylight hours, insurance often funds visits to adult day centers equipped with cooling facilities, he added. Carson De Fries, a PhD candidate in social work at Denver University, echoed many of these sentiments — stressing the need to provide older adults with places they can cool off during the day — and the transportation to get there. "Heat is incredibly dangerous to anyone, but especially older adults," she told The Hill in an interview this week. De Fries, who last summer co-authored a review focused on wildfires and older adults, likewise urged local-level action on the part of other community members. She encouraged neighbors and relatives to speak with older adults in the area, assess what their needs are and perhaps consult with caregivers and other experts about what actions could be most beneficial. In last year’s review, published in the International Journal of Environmental Research and Public Health, De Fries and her colleagues analyzed 75 studies that mainly focused on the health effects of wildfires — such as smoke exposure and poor air quality — on older adults worldwide. "Significant numbers of people delay evacuation during a wildfire event, often leading to increased evacuation danger," the authors observed. When contending with natural disasters, older adults are more prone to "mobility limitations, decreased social supports, difficulty maintaining necessary health regimens and limited access to information about disaster preparedness," according to the analysis. Chronic conditions, which are more common among older adults, may require specific diets and medicines — needs that can be challenging to fulfill during such events, the authors noted. "As a result of these age-related risks, older adults are disproportionately negatively impacted by natural disasters when compared to other age groups," they added. The authors cited Hurricane Katrina as an example — finding that about 71 percent of those who perished were older than 65, even though such individuals made up just 15 percent of the New Orleans population. Unlike hurricanes, which usually occur with some warning, De Fries noted that "wildfires can start quickly and spread quickly." At that point, older adults may either not be aware of the blaze in the first place or may not have the means to evacuate, she stressed. Amid the increasing threat of weather conditions so extreme that they warrant evacuation, the American Heart Association recently published a disaster-planning guide for older Americans. During Hurricane Ian in Florida in 2022, many of the 150 individuals who died were older adults who had heart-related issues, power outages, medical device failures or lack of access to care. Without a heads-up that evacuation may be imminent, affected individuals might not have time "to put a package together with medications and all the things they need on a daily basis,” Lindsay Peterson, of the University of South Florida, said in a statement included in the guidelines. "A lot of people say, 'I can't do this. I'm just going to hope for the best,'" she said. Chief among the document’s recommendations was the creation of an evacuation plan that includes these additional needs. Such a plan could involve going to a friend or relative's home or reaching out to local emergency agencies to learn what public resources might be in place. The guidelines also suggested copying all personal identification, medical records and insurance documents, as well as setting aside cash and extra medications in case a longer-term evacuation becomes necessary. During situations in which evacuation isn't critical but lengthy power outages are possible, the guidelines also urged older Americans to acquire a generator — and sufficient fuel — to keep medical devices functioning. Going forward, De Fries, from Denver University, said she believes it will also be critical for researchers to start speaking with members of this unique population themselves. "There's a lot of space for working with older adults more and hearing directly from them about what they need and what would be helpful for them during these times," she added.

These 5-Second Hand Exercises For Dementia Are Going Viral. Here's What Neurologists Think.

Is boosting your brain health really this simple?

Social media is full of health hacks for better sleep, clear skin, a functioning gut, you name it. Lately, a tip for aging and cognitive function is gaining traction. Videos showing hand and finger exercises have racked up millions of views on TikTok and Instagram, with users suggesting these movements can help prevent dementia or Alzheimer’s disease.The exercises include things like alternated clapping, tapping, arm circles and pointing your fingers in different directions. And although they might look easy enough, exasperated folks in the comments sections highlight that some of these motions are a lot harder than they appear. But does failing at intricate finger movements and hand coordination exercises mean you’re cognitively doomed? And can these exercises really ― as the captions claim ― prevent dementia or Alzheimer’s? HuffPost asked a neurologist to weigh in. “While there are a few studies showing that aspects of mild cognitive impairment might be improved with these types of hand exercises, I would put forward that there is nothing magical about these movements,” said neurologist Dr. Chris Winter.Hand exercises are a way to practice motor skills, which can be beneficial for maintaining cognitive abilities as we age. But it might be a stretch to suggest that specific movements are going to remove your risk of developing dementia or Alzheimer’s disease. Can simple hand exercises really prevent dementia?Winter explained that hand and finger coordination can be beneficial as part of a larger pattern of mental and physical activity, but it’s not the hand gestures themselves that matter ― it’s the engagement and concentration involved.“Learning to play the piano or other activities that force concentration and the practice of improved hand/eye coordination are potentially just as useful,” Winter said. “I recommend that people stay active and engage in appropriately challenging activities. Learn a new language, pick up a guitar or a used set of drums, play pickleball. If you have the capacity to do these things, get off of TikTok and go do these things instead.”Brain function is less about hand gestures and more about movement and mental engagement that challenge your mind and body overall. “While no single exercise can prevent Alzheimer’s disease, regularly engaging your brain in complex, novel activities helps build what we call ‘brain reserve.’ A higher brain reserve can delay the onset of dementia symptoms or reduce their severity later in life,” said Dr. Majid Fotuhi, a neurologist and author of “The Invincible Brain: The Clinically Proven Plan to Age-Proof Your Brain and Stay Sharp for Life.”Board-certified neurologist Dr. Luke K. Barr emphasized that TikTok viewers shouldn’t mistake their inability to do some of these hand exercises as a red flag for cognitive decline. If you have trouble alternating pointing your thumbs and pinkies, that doesn’t mean you’re “already developing dementia,” as some commenters fear. “These are complex exercises that are difficult, especially at first, and require a lot of concentration and practice,” Barr said. “Just because someone is not able to do it easily right away, does not necessarily mean that they have dementia.”As with most anything complicated, practice makes perfect. “I think there are a variety of reasons why one could not do these gestures ― or rub their stomach while patting their head,” Winter added. “While someone with significant dementia is probably not likely to be able to do these activities, the fact that someone struggles with coordination does not indicate dementia or progression in this direction. Ability to pat your hands together is not a diagnostic test for cognitive decline.”So while those quick coordination challenges might be fun or stimulating, experts say, your best bet for brain health still lies in the basics: regular exercise, quality sleep, a balanced diet and staying mentally and socially active.“Factors such as poor diet, sedentary lifestyle, obesity, diabetes, hypertension, sleep problems, chronic stress and excessive alcohol can contribute to shrinkage in the brain,” Fotuhi said. “Along with genetic and environmental factors, these lifestyle and medical factors can damage small blood vessels, reduce rinsing mechanisms in the brain, cause ‘leaky brain’ and increase brain inflammation ― which over time lead to cognitive decline and Alzheimer’s disease. So rather than worrying about one task, it’s better to focus on overall brain health habits.”Ultimately, what exercise and mental stimulation mean can vary based on individuals’ abilities. “If you only have the capacity to practice hand gestures, then that’s OK too,” Winter said. But just remember that the real “hack” for keeping your brain sharp isn’t a social media exercise ― it’s a holistic approach to living a healthy, mindful and engaged life.

Under Current Guidelines, Most Lung Cancer Patients Weren't Eligible for Cancer Screening

By Ernie Mundell HealthDay ReporterMONDAY, Nov. 24, 2025 (HealthDay News) — Under current screening guidelines, almost two-thirds of Americans with lung cancer would not have qualified for the CT chest scans that could have spotted tumors early and extended their lives, new research shows. The finding hits home for 38-year-old Carla Tapia, a mother of three from Beltsville, Maryland. She smoked a bit in her youth but had kicked the habit by 18. Nevertheless, Tapia first developed respiratory symptoms in 2018, and was diagnosed with inoperable stage 4 lung cancer in 2020. After numerous chemotherapies failed, Tapia received a life-saving double-lung transplant at Northwestern Medicine in Chicago in 2024. She’s now attending college back at home in Maryland.According to Tapia, it's an ordeal timely screening might have prevented.“I keep hearing stories about young people being diagnosed with lung cancer, and if we could expand the screening guidelines, I believe more lung cancers could be caught at earlier stages, and more lives would be saved,” she said in a Northwestern Medicine news release.Current guidelines from the United States Preventive Services Task Force (USPSTF) advise annual CT chest scans for adults ages 50 to 80 who have a 20 pack-year smoking history and currently smoke or have quit within the past 15 years. According to study senior author Dr. Ankit Bharat, those eligibility guidelines are too restrictive and miss many people still at risk for the leading cancer killer.“We moved to universal age-based screening for breast and colon cancer with tremendous success, and we need to move to the same approach for lung cancer,” Bharat said in a Northwestern news release. “Chest screening offers something unique — with one low-dose scan, we can assess lungs, heart and bones comprehensively. This baseline scan becomes invaluable for monitoring their health over time,” said Bharat. He is chief of thoracic surgery and executive director of the Northwestern Medicine Canning Thoracic Institute.Lung cancer can strike anyone, including people who only smoked a short amount of time and even never-smokers. And, as happened in Tapia’s case, nearly 80% of the time lung cancers are first diagnosed in an advanced stage. The new study was published Nov. 20 in JAMA Network Open. It tracked nearly 1,000 consecutive patients whose lung cancers were treated at Northwestern Medicine.Based on their history of smoking (including never-smokers), Bharat’s group estimated that only 35% would have been eligible under USPSTF guidelines to be referred to annual lung CT scanning. Women and never-smokers made up a significant number of those who would have been excluded from eligibility for screening, the researchers said.They believe that moving to a universal screening approach — recommending lung screens for everyone ages 40 to 85 — could spot more tumors early, boost the cost-effectiveness of lung cancer care, and help level the playing field for disadvantaged Americans. According to the researchers, a typical lung CT scan takes less than 10 seconds and doesn’t require any intravenous imaging dyes. Bharat notes that the leftover effects of the COVID-19 pandemic could mean heightened risks of other lung illnesses among relatively young Americans."Nearly six years after the pandemic's start, we're seeing increasing numbers of patients with lung scarring and fibrosis from COVID-19, especially those who get reinfected with respiratory viruses," he said. “The damage compounds with each infection. Early detection through comprehensive screening can help us intervene before these conditions progress to requiring [lung] transplantation.”Northwestern’s Lung Health Center created a list of patient types who might want to consider lung screening:COVID-19 survivors who are having ongoing respiratory issues People exposed to contaminants such as wildfire smoke, industrial pollution or high radon levels People with family histories of lung disease or pulmonary fibrosis Those exposed to secondhand smoke, vaping or marijuana use Asian women and other demographics at elevated risk for lung conditions Anyone seeking baseline chest health assessment “We're seeing younger patients with respiratory problems from vaping, environmental exposures and COVID-19 who would never qualify for traditional screening,” said study co-author Dr. Scott Budinger, chief of pulmonary and critical care at the Canning Thoracic Institute.A more inclusive approach to screening “allows us to catch interstitial lung disease, pulmonary fibrosis, lung cancer and other conditions years before they'd typically be diagnosed,” he said in the news release.SOURCE: Northwestern Medicine, news release, Nov. 20., 2025Copyright © 2025 HealthDay.

New Flu Variant Could Bring Another Severe U.S. Season

THURSDAY, Nov. 20, 2025 (HealthDay News) — A new flu variant spreading overseas may set the stage for another tough winter in the United States, experts warn.The strain, called subclade K, has caused a rise in flu cases in the United Kingdom, Canada and Japan. And now signs suggest it is beginning to take hold across the United States as flu activity rises.According to the latest U.S. Centers for Disease Control and Prevention (CDC) FluView report, reported flu activity in the United States remains low but is climbing quickly.Last year’s flu season was the worst the United States had seen in nearly 15 years and led to at least 280 child deaths, according to the CDC.Most cases this year are from the H3N2 virus and about half of those belong to the subclade K variant, the same strain that fueled a difficult flu season in the Southern Hemisphere.Because it wasn’t circulating widely when strains were selected for the vaccine update, this year’s flu shot targets close strains of the virus."It’s not like we’re expecting to get complete loss of protection for the vaccine, but perhaps we might expect a little bit of a drop-off if this is the virus that sort of dominates the season, and early indications are that’s probably going to be the case," Richard Webby, a researcher at St. Jude Children’s Research Hospital in Memphis, Tennessee, told CNN.Early findings from the UK Health Security Agency suggest the variant carries seven genetic changes on a major part of the virus, making it a bit harder for the body's immune system to recognize.Even so, they found that the flu shot has reduced the risk of hospitalization or emergency care by about 75% in children and 30% to 40% in adults so far this season.What worries experts even more is that fewer Americans appear to be getting the flu shot.Data from IQVIA shows that pharmacies gave 26.5 million flu vaccinations from August through October, down from 28.7 million during the same period last year."I’m not surprised," Jennifer Nuzzo, professor of epidemiology and director of the Pandemic Center at Brown University in Providence, Rhode Island, said.She said recent debates about vaccine safety have "left people confused but possibly at the worst have left people worried about getting vaccinated."Australia’s flu shot rates also fell this year and the country went on to record more than 443,000 cases."What they saw in Australia is that they had a bad season. And so it’s concerning for you and us, what’s coming," Dr. Earl Rubin, division director of infectious disease at Montreal Children’s Hospital, told CNN.Several early indicators already show flu levels rising in the U.S.The WastewaterSCAN network found type A flu in 40% of samples in November, up from 18% in October, according to Marlene Wolfe, an assistant professor in the department of environmental health at Emory University in Atlanta.Only four U.S. monitoring sites in Maine, Vermont, Iowa and Hawaii have officially crossed the threshold for declaring flu activity high, but experts say the trend is clear.While it’s not yet clear whether subclade K could cause more severe illness, a rise in infections alone could cause hospitalizations to skyrocket, Rubin noted."It’s not too late. Go and get your flu shot," Dr. Adam Lauring, chief of the division of infectious diseases at the University of Michigan Medical School, in Ann Arbor, said.These results are preliminary and have not yet been peer-reviewed.The Texas Department of State Health Services (DSHS) has more on the flu vaccine.SOURCE: CNN, Nov. 18, 2025Copyright © 2025 HealthDay.

Thousands of US Hazardous Sites Are at Risk of Flooding Because of Sea Level Rise, Study Finds

A new study finds that thousands of hazardous sites across the U.S. are at risk of flooding due to sea level rise that could pose public health threats to neighboring communities

If heat-trapping pollution from burning coal, oil and gas continues unchecked, thousands of hazardous sites across the United States risk being flooded from sea level rise by the turn of the century, posing serious health risks to nearby communities, according to a new study.Researchers identified 5,500 sites that store, emit or handle sewage, trash, oil, gas and other hazards that could face coastal flooding by 2100, with much of the risk already locked in due to past emissions. But more than half the sites are projected to face flood risk much sooner — as soon as 2050. Low-income, communities of color and other marginalized groups are the most at risk.With even moderate reductions to planet-warming emissions, researchers also determined that roughly 300 fewer sites would be at risk by the end of the century. “Our goal with this analysis was to try to get ahead of the problem by looking far out into the future," said Lara J. Cushing, associate professor in the Department of Environmental Health Sciences at the University of California, Los Angeles who co-authored the paper published in the science journal Nature Communications.“We do have time to respond and try to mitigate the risks and also increase resilience," she added, speaking at a media briefing Wednesday ahead of the study's release. The study was funded by the Environmental Protection Agency and builds on previous research from California. Climate change is driving and accelerating sea level rise. Glaciers and ice sheets are melting, and the sea's waters are expanding as they warm. In many places along the coastal U.S., sea level rise is accelerating faster than the global average because of things like erosion and land sinking from groundwater pumping, according to the National Oceanic and Atmospheric Administration. Thomas Chandler, managing director at the National Center for Disaster Preparedness at Columbia University who was not involved in the research, said it’s “a really important study” that the public, policy makers and government agencies “need to make note of.” Derek Van Berkel, an associate professor in the school for environment and sustainability at University of Michigan who was also not involved in the study, wasn't surprised to learn about the disproportionate risks. What was “alarming” was considering the magnitude of “feedback effects” from flooding, he said. How researchers approached the data The study's researchers started by identifying and classifying tens of thousands of hazardous sites near the coasts of Puerto Rico and the 23 states with coastline. Next, they wanted to know each site's projected future flood risk. They did this by calculating how likely each year coastal flooding could inundate a site using historical sea level measurements and projected sea level rise in 2050 and 2100 under low and high emissions scenarios. Lastly, they identified and classified communities as being at-risk if homes are located within 1 kilometer (0.62 miles) of a hazardous site with a high threat of future flooding, and compared those communities' characteristics with other coastal neighborhoods with no at-risk sites nearby. But researchers did not include all types of hazardous facilities, such as oil and gas pipelines, nor did they account for groundwater upwelling or more intense and frequent storms in the future, which could lead to underestimates. On the other end, the flood-risk model they used could have overestimated the number of threatened sites. “It is important to note that previous disasters, such as hurricanes Katrina, Rita and Harvey, did result in a lot of toxic contamination from oil and gas pipelines,” Chandler said. The 5,500 at-risk sites includes 44% that are fossil fuel ports and terminals, 30% power plants, 24% refineries and 22% coastal sewage treatment facilities. Most of the sites — nearly 80% — are in Louisiana, Florida, New Jersey, Texas, California, New York and Massachusetts. Potential health impacts from exposure to hazards People exposed to flood waters near industrial animal farms or sewage treatment plants could be exposed to bacteria like E. coli, said Sacoby Wilson, professor of global, environmental and occupational health at the University of Maryland during the briefing. Symptoms can include bloody or watery diarrhea, severe stomach cramps or vomiting and fever. Those living near industrial sites like refineries could be exposed to heavy metals and chemicals that can cause rashes, burning of the eyes, nose and throat, headaches or fatigue, added Wilson, who was not involved in the study. “For folks who are vulnerable, maybe have an underlying health condition, those health conditions could be exacerbated during those flood events.” Longer term, some of these exposures could contribute to cancer, liver, kidney or other organ damage, or have reproductive effects, he said. For Chandler, the Columbia University director, the study highlights the need to heavily invest in hazard mitigation. “It's really important for federal, state and local governments in the United States to address these factors through multi-stakeholder resilience planning and encouraging local governments to integrate climate risk assessments into their mitigation strategies.”The Associated Press receives support from the Walton Family Foundation for coverage of water and environmental policy.
