Common-Sense Measures Could Curb Heat-Related Deaths

Common-Sense Measures Could Curb Heat-Related Deaths

Extreme heat is the number-one weather-related killer in the U.S., causing hundreds to thousands of deaths every year. And available estimates are assuredly undercounts because heat is not always accounted for on death certificates. The need to protect people is becoming clearer and more urgent as heat waves happen more often, last longer and become hotter with climate change.
Fully dealing with the threat would mean tackling systemic issues, from mitigating climate change to rectifying inequities in who is exposed to heat and can afford to cool themselves off. But there are also common-sense protections that could—and should—be put in place by both businesses and our government to prevent heat illnesses and deaths. These changes make economic sense, but more important, they are the humane thing to do.
If we want people to do their jobs optimally, we should give them the protection they need to do so.

Extreme heat can cause heat exhaustion (characterized by nausea, dizziness and muscle cramps), heatstroke (an elevated core body temperature, often higher than 104 degrees Fahrenheit, which can damage organs if not promptly treated), and even death. Older people, those with certain health conditions or taking certain medications, and outdoor workers are particularly at risk of heat illness. Outdoor laborers can be especially vulnerable because, in addition to the danger posed by the ambient heat, their work often raises their body temperature.
The U.S. Bureau of Labor Statistics documented 34 heat-related deaths of workers per year between 1992 and 2022, as well as an annual average of 3,389 injuries and illnesses that caused people to miss days of work between 2011 and 2022. And an examination of workers' compensation claims in California that included more cases than just those where people missed work found three to six times the number of illnesses and injuries compared with the Labor Bureau's records for that state.
A few states, such as California and Oregon, have enacted protections for workers following the rubric of 'water, rest, shade'—workers should have ready access to drinkable water and ample rest breaks, ideally in air conditioning and at least in shade, to allow the body to cool and recover. The physiological science behind these interventions is clear, and formal protections requiring these measures have worked.
But piecemeal state legislation leaves many workers unprotected. Scientists and policymakers have argued for a federal standard set by the Occupational Safety and Health Administration (OSHA) since the agency's inception in the 1970s. In 2024 OSHA finally proposed a rule that would require not only access to water, rest breaks, and shade or other cooling areas but also heat safety training and protocols to acclimatize new and returning workers to high-heat conditions. As with many rules proposed late in the Biden administration, its fate depends on the Trump administration's willingness to put the safety of the American population first.
The current administration should see this rule through—and maintain robust OSHA staffing to enforce it—because it would not only avert highly preventable deaths but also improve economic productivity. Research shows that unrelieved exposure to high heat impairs concentration, coordination and decision-making. If we want people to do their jobs optimally, we should give them the protection they need to do so.
Some businesses have opposed heat health rules, arguing that they impose expenses and that people should be responsible for themselves—an Oregon farm company made this argument after the death of one of its workers before the state enacted its heat safety law. But most of these measures are relatively inexpensive. In addition, heat illness is notoriously difficult for anyone to recognize in themselves, and as a vulnerable class, laborers sometimes avoid taking voluntary breaks for rest or water because they believe doing so will make their bosses think they aren't hard workers and might cost them their jobs.
Existing state rules and the proposed OSHA standard give businesses flexibility in implementing protections: farms may need to have mobile hydration and cooling stations, whereas an oil and gas facility might be able to erect permanent shaded areas for its workers. The goal is to keep people safe, not to impose rigid burdens on businesses.
For these reasons, it would actually be in the economic interest of companies, especially ones that operate in multiple states, to lobby the administration to maintain the rule so they can avoid the patchwork of requirements across the country (although states would still be allowed to institute stricter rules on their own).
In 2015 California strengthened its rules about worker protection and saw positive changes. Part of this success was the result of better enforcement. That is another reason to put an OSHA heat safety standard in place: a specific standard would greatly simplify enforcement. Under a current rule known as the General Duty Clause, the agency must go employer by employer and meet a list of criteria to enforce action.
If the Trump administration does not keep the federal rule, states must be ready to step into the breach to protect workers. They need not reinvent the wheel—the proposed OSHA rule, as well as regulations passed in states such as California and Oregon, could be readily adapted to other places.
Further, states such as Texas and Florida that have passed laws banning local jurisdictions from enacting heat safety regulations must reverse course. Texas and the Southeast have seen some of the largest increases in the number of days when heat and humidity rise to dangerous levels, meaning workers in those states are protected only if they are fortunate enough to work for a company that voluntarily provides adequate safety measures. Protecting people, not just businesses, is the government's job.
Providing access to very basic cooling measures is an overall inexpensive way to keep people safe and has the side benefit of economic efficiency. As Sharon Block, a Harvard Law School professor and labor lawyer, puts it, 'it's not just the decent thing to do but the smart thing to do.'

A northern Arizona county is reporting 4 measles cases, the state's first in 2025

Health officials in Navajo County in northern Arizona say they've confirmed four measles cases, which are the first cases of the highly contagious respiratory virus in Arizona in 2025. The announcement from the Navajo County Public Health Services District June 9 came amid a national surge of measles, with 1,168 cases reported to the U.S. Centers for Disease Control as of June 6, which is more than four times the number reported during all of 2024. Compounding the threat for Arizonans are recent cases in five neighboring states: California, Colorado, New Mexico, Texas and Utah. The four cases in Navajo County involve people who were not vaccinated against measles. The four were infected from a single source and have a recent history of international travel, health district officials say. Public health officials are trying to identify locations where exposure may have happened and are in the process of identifying people who may have been exposed, the Navajo County health district said in a written statement. Officials estimate the "potential exposure" dates were between May 17 and May 28 and said anyone who may have been exposed should monitor for symptoms for 21 days after exposure. Symptoms include a high fever of more than 101 degrees Fahrenheit, a cough, runny nose, red or watery eyes and a rash beginning at the head and spreading downward A measles outbreak that began earlier this year in Texas killed two unvaccinated school-age children, resulted in 94 hospitalizations and totaled 742 cases overall. In a related outbreak, New Mexico health officials as of June 3 reported 81 measles cases and the death of one adult who tested positive for measles. Arizona is particularly vulnerable to a measles outbreak because community protection has been waning as an increasing number of parents and guardians are choosing not to vaccinate their children with the Measles, Mumps and Rubella vaccine, known as MMR. There likely are several reasons for the decline, including problems accessing the vaccine, vaccine skepticism and a lack of scientifically accurate education about the risks and benefits of immunization against vaccine-preventable diseases such as measles. Measles can affect people of any age and cause an array of complications, including deafness, blindness and brain inflammation, in addition to death. Two doses of the MMR vaccine are 97% effective in protecting against measles infection, evidence shows. Reach health care reporter Stephanie Innes at or follow her on X: @stephanieinnes.

The most depressing jobs in the country revealed in new study

Job seekers may want to consider the toll that specific careers can have on their mental health. A huge new study published on Friday examined the relationship between careers and depression rates. The study analyzed survey data from 536,279 workers across 37 states from 2015 to 2019. Out of half a million U.S. workers, 80,319 of them admitted to being diagnosed with depression at some point during their lives, with women being diagnosed twice as often as men. Separating the results by industry, the study saw that people who worked in community and social services had the highest rate of lifelong diagnosed depression at 20.5 percent. The second highest on the list was food prep and serving jobs at 20.1 percent. Other industries with high lifetime diagnosed depression rates are: arts, entertainment, sports, and media at 18.6 percent; accommodation and food services at 18.4 percent; health and social assistance at 18.2 percent; retail trade at 17.7 percent; and legal, education, and library jobs tied at 16.1 percent. Industries with lower lifetime diagnosed depression rates included mining jobs at 6.7 percent, construction at 8.9 percent, and agriculture and engineering jobs at nine percent. Although mining and construction may have lower depression rates, those industries also have the highest suicide rates among U.S. workers. The researchers suggest that the gap may be explained because blue-collar men are less likely to seek mental services due to a preexisting stigma or limited access in rural areas. Despite the results of the study, there are some jobs out there that are almost stress-free and also come with a large paycheck. Back in December 2024, Resume Genius released its list of the highest-paying jobs that also reported low levels of stress. Their study described 'low-stress jobs' as ones that typically require fewer demands, more predictable work hours, supportive environments, and manageable workloads. All of the jobs on the list required the person to have at least a Bachelor's degree. The list was compiled using data from the U.S. Bureau of Labor Statistics (BLS) and the career site O*NET Online. The high-stress jobs were filtered out using O*NET and then cross-referenced against the BLS's Occupational Outlook Handbook, with the national median salary set at $48,060 and viewing jobs that showed 'faster-than-average growth.' The best jobs included: water source specialist, astronomer, actuary, environmental economist, mathematician, and geographer.

Science-Backed Ways to Stay Healthy During Salmonella Outbreak in Eggs

3 min read To prevent salmonella food poisoning, refrigerate your eggs, cook them well, never eat them raw, and clean, clean, clean By edited by Dean Visser At least 79 people have been sickened by a salmonella outbreak linked to organic and cage-free eggs, distributed under various brand names across seven U.S. states. The eggs were processed by the August Egg Company in Hilmar, Calif., according to the Food and Drug Administration (FDA). On June 6, after FDA tests discovered the bacteria, the company issued a wide recall. The recall is just the latest in a string of callbacks linked to salmonella contamination. On June 7, TGD Cuts of Jessup, Md., recalled cucumber and salsa products, and on June 4 the FDA urged consumers to follow a recall that began in May of tomatoes packaged and shipped by various companies. What is salmonella, how can it make you sick, and how can you minimize your chances of getting it? Here are some basics.

Salmonella is a bacterium that thrives in the intestinal tract of certain animals, including chickens and cows—and humans. It is shed through feces. Like many foodborne pathogens, salmonella is often spread by improper cleaning or handling of raw food—including meat, eggs, seafood, vegetables, fruits and rice—at farms or factories. It is often associated with chicken and eggs, although past outbreaks have also been linked to peanut butter, raw pork and beef, cucumbers and even raw flour in cookie dough. When compromised products are shipped, stores and consumers may be unaware of the contamination until enough people start becoming sick and investigators trace the source back to specific food lots. The U.S. Centers for Disease Control and Prevention (CDC) estimates that 48 million Americans get sick from food each year. What Are the Symptoms of Salmonella Food Poisoning? You may begin to feel sick anywhere from eight to 72 hours after you are exposed. As the bacteria multiply, they can cause stomach cramps, diarrhea, vomiting and fever. Children under age five often account for a large percentage of cases in a Salmonella outbreak, and elderly people or those with weakened immune systems are at greater risk. In rare cases people develop joint pain or eye irritation. How Is It Treated? Infections often clear within three or four days, but if diarrhea lasts for more than two days, or body temperature rises above 102 degrees Fahrenheit, health officials urge you to see a doctor. Complications such as diarrhea can cause dehydration, so drink plenty of fluids. How Can I Minimize My Chances of Getting Salmonella? Contaminated food is the chief source, so never eat raw foods that can carry the bacteria. Refrigerate eggs or other susceptible foods at 40 degrees Fahrenheit or less. When preparing meals, use separate cutting boards and knives for suspect foods, and thoroughly wash them—as well as kitchen surfaces and your hands after prep. Microwave dishwashing sponges on high. Cook food to at least 160 degrees Fahrenheit (71 degrees Celsius). Should I Stop Kissing my own Chickens? Birds, hedgehogs, turtles, guinea pigs and even pet bearded dragons can carry Salmonella and make you sick through direct contact, according to a 2024 Scientific American story. The craze among homeowners that expanded during Covid to raise chickens in the backyard is also a culprit. Salmonella bacteria can linger on an animal's skin, so regardless of how cute you think your chickens are, try to not snuggle them or kiss them! Which evidently is a thing.
