Get ahead of allergy season this year
That sneezy, itchy, watery-eyed time of year has yet again returned: it's allergy season. Seasonal allergies are the body's response to pollen from trees and grass; the immune system releases chemicals, like histamines, leukotrienes, and prostaglandins, which cause all those uncomfortable, familiar symptoms.
The best way to combat the unpleasant barrage is to get ahead of them, says Russell Leftwich, a fellow at the American Academy of Allergy, Asthma, and Immunology and an adjunct assistant professor of biomedical informatics at Vanderbilt University School of Medicine. Since allergy season arrives at roughly the same time every year, Leftwich recommends starting your allergy relief of choice for a few days before pollen levels get too high. (The Weather Channel, AccuWeather, and IQAir provide local pollen monitoring.)
If the dizzying variety of drugs at the pharmacy has you confused, here are a few things to know about the most effective types of over-the-counter allergy medications as well as non-pharmaceutical ways to keep your allergies in check.

Before heading to the drugstore
One of the best ways to alleviate allergy symptoms is to prevent pollen from getting into your body in the first place. This means keeping windows closed and wearing a mask while doing yard work, Leftwich says. If you've been outdoors for a while, change your clothes and wash your face when you get home, says Rita Kachru, the chief of allergy and immunology in the department of medicine at UCLA.

Another prevention method includes rinsing your nose with a saline solution: a mixture of baking soda, salt, and distilled or boiled water, Kachru says. The American Academy of Allergy, Asthma, and Immunology recommends mixing three tablespoons of iodide-free salt with one teaspoon of baking soda in a small container. Then add one teaspoon of the salt/baking soda mixture to eight ounces of lukewarm distilled or boiled water. You can also buy nasal saline sprays at the drugstore.
When to take antihistamines
When avoidance strategies aren't totally effective, you can treat your symptoms with over-the-counter allergy medications. One of the major categories of these treatments are antihistamines, which are available in pill, tablet, eye drop, or nasal spray forms.
Antihistamines help reduce itchiness and sneezing and are your first line of defense, Kachru says. 'The reason I always start with an antihistamine is because you may just have a day of a high pollen count,' she says, 'and you just need a one-time antihistamine because you're sneezing and you're itchy and you're a little congested.'
Kachru and Leftwich suggest opting for long-acting antihistamines — like loratadine (Claritin), cetirizine (Zyrtec), or fexofenadine (Allegra) — over short-acting ones. People can develop a resistance to short-acting antihistamines, like diphenhydramine (Benadryl), very quickly. Plus, Benadryl often makes people sleepy.
Both short- and long-acting antihistamines provide relief within 15 to 30 minutes, Kachru says. Take them at the start of the day before you are exposed to pollen.
For mild nose itchiness and sneezing, an antihistamine nasal spray, like azelastine (Astepro), might work for you. A common side effect is a metallic taste in the back of the throat, Kachru says.
When to try nasal steroid sprays
If you're reaching for an antihistamine three to four times a week, Kachru suggests adding a nasal steroid into the mix. Not only do nasal steroids reduce sneezing and itchiness, but they'll help with congestion, too. These include fluticasone (Flonase), budesonide (Benacort), triamcinolone (Nasacort), and mometasone (Nasonex). Nasal steroids do take a few days until you feel the full effects, Kachru says, so don't give up if you don't feel better right away.
To properly administer nasal sprays, insert the tip in your nostril and point it toward your ear. A common mistake when using a nasal spray is pointing it straight up your nose. 'It goes up their nose, down their throat and does nothing for them,' Kachru says. 'Or they stick it inwards into their nose, and then they get nosebleeds. … So you want to always make sure that when you put it in, you point it out towards your ear, spray, sniff in, and then do the alternate nostril.'
While not a nasal steroid, Kachru advises against using oxymetazoline (Afrin), a nasal spray decongestant. 'Patients who use Afrin regularly end up having really, really severe rebound nasal congestion,' she says.
Leftwich advises against decongestants more broadly, as the over-the-counter decongestant medications are not very effective.
After a few weeks of daily nasal spray use, you may consider stopping an antihistamine, if you're taking both. 'That's usually what I tell people to do,' Kachru says. 'Eventually just use that antihistamine as needed' because the nasal spray is more effective.

The health risks from climate change that almost no one talks about
is a staff writer at Grist covering climate change and its effects on human health. Her work can also be found in Wired, Rolling Stone, the Associated Press, and other outlets. A woman and her child on the Panbari tea estate in Assam, India. Over years, pregnant women working on the plantations have been subjected to long hours with little to no accommodation of their basic needs for food, hygiene, latrines, and lesser work story is a collaboration between Vox and Grist and builds on Expecting worse: Giving birth on a planet in crisis, a project by Vox, Grist, and The19th that examines how climate change impacts reproductive health — from menstruation to conception to birth. Explore the full series here. Climate change poses unique threats to some of the most foundational human experiences: giving birth and growing up. That's the conclusion of a recent summary report compiled by researchers at the London School of Hygiene and Tropical Medicine, which shows that climate change is exposing tens of millions of women and children to a worsening slate of physical, mental, and social risks — particularly if they live in the poorest reaches of the globe. Extreme heat, malnutrition linked to crop failures, and air pollution caused by the burning of fossil fuels are driving higher rates of preterm birth and infant and maternal death, undermining many countries' efforts to improve public health. Already, 1 billion children experience a level of risk that the report characterizes as extreme. 'We're still just beginning to understand the dangers,' the authors wrote in their review of the limited existing scientific literature on the subject, 'but the problem is clearly enormous.' Here are the 5 biggest takeaways: Extreme heat is particularly dangerous for pregnant women and newborns. High temperatures are linked to premature births, stillbirths, low birth weight, and congenital defects, the report said, pulling from a study conducted by Drexel University researchers in Philadelphia who found that, for every 1.8 degrees that the city's daily minimum temperature rose above 75 degrees Fahrenheit, the risk of infant death grew about 22 percent. 'Whatever associations we're seeing in the U.S. are much, much greater in other areas, particularly the areas of the world that are most impacted by heat and then also already impacted by adverse birth outcomes,' said Rupa Basu, chief science advisor for the Center for Climate Health and Equity at the University of California, San Francisco. 'This is the tip of the iceberg,' added Basu, who was not involved in the new report. Heat waves also raise the odds of early birth by 16 to 26 percent, according to the report, and women who conceive during the hottest months of the year are at higher risk of developing preeclampsia, a pregnancy complication that can become dangerous if left untreated. In The Gambia, where 70 percent of the agricultural workforce is female, a survey of pregnant farmers conducted by London School of Hygiene and Tropical Medicine researchers found that women were being exposed to conditions that overwhelmed their capacity to regulate their internal temperatures 30 percent of the time. Up to 60 percent of women exhibited at least one symptom of heat stress and heat-related illness, such as vomiting and dizziness. Diagnostic tests showed that a third of pregnant farmers showed signs of acute fetal strain. Air pollution is a silent killer. The burning of fossil fuels — and a related surge in wildfires burning over the earth's surface — are likely linked to a staggering proportion of low birth weight cases globally: 16 percent, according to the report. That's because the combustion of fossil fuels such as coal, oil, and gas produces tiny toxic molecules, and wildfire smoke contains fine particulate matter that is infamous for causing a slew of adverse health effects. At least 7 million children in the U.S. are exposed to wildfire smoke every year, and that number is rising quickly as rising temperatures have driven a doubling of extreme wildfire activity around the globe over the past 20-some years. In 2010, researchers linked 2.7 to 3.4 million preterm births around the world to air pollution exposure. 'Risky, sublethal effects of air pollution are also coming into focus,' the report continues. One study conducted using data on 400,000 births in southern California found that a woman's exposure to fine particulate matter during pregnancy may increase her odds of spontaneous preterm birth by 15 percent, especially if that exposure happens during the second trimester. Mothers may face mental health burdens as a result of air pollution, too: The odds of postpartum depression rose 25 percent in women exposed to a range of different types of air pollution in their second trimester. Pregnant people march during a rally for climate action in Sydney, change is already causing serious and measurable harm to children. One billion children worldwide are at 'extremely high risk' from the effects of climate change — meaning they live in areas prone to sudden, disruptive environmental shocks and already experience high levels of poverty, food insecurity, and lack of access to medical infrastructure. The African continent, which is home to countries with some of the highest mortality rates for children under 5 years old in the world, saw a 180 percent increase in flooding between 2002 and 2021. And a study of 37 African countries published last year identified a steep rise in infant mortality due to drowning and waterborne diseases caused by flooding in the past five years. (Exposure to repeated flooding can overwhelm sewage systems and contaminate drinking water supplies with fecal matter and other pollutants that can lead to disease.) Climate-driven drought in Africa is contributing to another adverse health outcome: malnutrition. Since 1961, climate change has led to a 34 percent decrease in agricultural productivity across the continent, according to the report. A deadly cycle of drought and flooding has wiped out crop yields, contributing to stubbornly high rates of infant malnutrition in many sub-Saharan African countries. These problems will get worse, but how much worse depends on how much global emissions continue to rise. The report modeled what different emissions scenarios would mean for maternal and child health in two countries: South Africa and Kenya. In a low emissions scenario, in which average warming is limited to 1.5 degrees Celsius — or 2.7 degrees Fahrenheit — globally, childhood mortality in both countries would decline between 2040 and 2059, thanks in large part to projected gains in safeguarding public health that are already in the works. Those gains, however, are predicated on sustained aid from developed countries like the U.S., which have produced the lion's share of emissions driving the climate crisis. The Trump administration has made seismic changes to America's international funding infrastructure in recent months, including effectively eliminating the United States Agency for International Development (USAID) and its related aid programs. A medium emissions scenario, where average global temperatures increase by 2.5 degrees to 3 degrees Celsius, would override that expected progress, leading to a 20 percent increase in child mortality rates in South Africa and stable rates in Kenya, where there has been much investment in protecting child health. Preterm birth rates in both countries would also rise substantially even with low rates of planetary warming. Worldwide, climate-driven malnutrition could lead to an additional 28 million underweight children over the next 25 years. Regardless of which emissions path the world ends up following, a shift toward a more isolationist approach among the world's richest countries threatens to exacerbate the risks pregnant women and children already face. As the planet continues to warm, those risks will keep multiplying. We don't have to wait for global warming to stop to save lives. Much can be done to prevent suffering right now. Solutions range from the straightforward to the complex: City planners can plant more trees in urban areas to keep pregnant people and children, whose internal systems are prone to overheating, cool. Organizations can identify ways to get public health data from the most underresourced parts of the globe. And nations can take steps to incorporate maternal and child health into their climate plans. Both sets of solutions are achievable, and there are precedents. Since 2013, for example, local air pollution strategies in Chinese megacities have been forcing rates of respiratory illness down dramatically, an echo of what happened in the U.S. after the passage of Clean Air Act amendments in 1970. To combat climate-driven harm today, nations can direct resources to maternal health wards, cooling technologies for buildings, and flood-resistant infrastructure. They can also update building codes to make sure hospitals and other health facilities are keeping their patients safe from extreme weather events. Getting nutritional supplements to pregnant people in countries dealing with high rates of food insecurity can offset some of the dangers of malnutrition; researchers have found that reducing vitamin deficiency in pregnant mothers slashed neonatal mortality by nearly 30 percent. In Philadelphia, city leaders implemented a $210,000 early warning system for extreme heat in 1995. It saved the city nearly $500 million in diverted costs over its first three years of operation. The new report argues that more cities in the U.S. and around the world should implement similar measures.

The surprising origins of the 'wellness' boom
is the host of Explain It to Me, your hotline for all your unanswered questions. She joined Vox in 2022 as a senior producer and then as host of The Weeds, Vox's policy podcast. 'Wellness' is a word influencers use as a hashtag on videos of them pouring collagen into smoothies and as the theme of a celebrity chef's new cookbook. It's even an obsession of the US health secretary. But what does it mean to be well? That's the question we answer this week on Explain It to Me, Vox's call-in podcast that answers the questions that matter to you most. While the multibillion-dollar industry feels new, it's been over a century in the making. Jonathan Stea, a clinical psychologist and author of Mind the Science: Saving Your Mental Health From the Wellness Industry, says that a lot of wellness trends fill in gaps in health care. That cold plunge or super food may be harmless, but often the science behind the trends can be iffy. 'The problem is that one of the ways in which wellness promoters market their materials is by promoting quote-unquote 'science' or 'research' to support their claims,' he says. 'When you do a deeper dive into that research, what people will often find is that you can find a study to promote or to support any kind of treatment or claim.' How did the wellness trend even begin in the first place? And how should we be thinking about our health overall? Below is an excerpt of our conversation with Stea, edited for length and clarity. You can listen to the full episode on Apple Podcasts, Spotify, or wherever you get podcasts. If you'd like to submit a question, send an email to askvox@ or call 1-800-618-8545. Where did wellness originate? We can trace the modern wellness industry back to about the late 19th century. That's when two prominent figures really played a role in shaping the modern wellness industry we see today. One of those players was a guy named John Harvey Kellogg. And what he and his brother Will Keith did is, they built something called the Battle Creek Sanitarium, which was a really huge famous medical center. It was a spa, it was a grand hotel, and it attracted a lot of wealthy, highly influential people. And what John ended up doing in that center was promoting a lot of his ideas about health and about how to treat diseases. They tended to really blend a lot of what he called Biologic Living, which is really just a kind of virtuous way of approaching our health and kind of blending that with some religious Christian beliefs. When I hear the name Kellogg, I admit that I think of my breakfast cereal. Was John Kellogg a scientist or an inventor of some kind? Kind of, yes. So his brother Will Keith actually started the cereal company. John was a physician, and he was a bestselling author. He had a magazine; he did lectures. His magazine was followed by millions of people. So was he the inventor of wellness as we know it today? Not quite. When he was promoting his ideas, it was before the term wellness as we use it today was formed. He was promoting a precursor to wellness called Biologic Living, which essentially promoted the idea that all diseases in all health conditions can be treated with basically a trifecta recipe of good sleep, good exercise, and eating a specific diet: vegetables and fruits, etc. Exercise, diet, sleep, eating fruits and veggies — that feels like something I hear from my doctor. Totally. That's a part of evidence-based care, and that's really foundational to what we do in the hospital. The problem is that what we see even in the modern wellness industry is when people sell these things as a cure-all, as a panacea for all health conditions. John had a lot of ideas that [suggested] if we weren't following a trifecta recipe of sleep, eating well, and exercise, and we were doing other things like drinking alcohol or eating meat or sugar, or even if people were overweight — he considered that to be non-virtuous, and essentially really bad behaviors. And he would view it in a very punitive way. Even masturbation was considered self-abuse by John Kellogg, and he thought that it would lead to things like mental illness and cancer and moral destitution. He would advocate treating people who would masturbate — in boys, he would recommend circumcision or bandaging their hands together, and in girls, he would recommend [applying] pure carbolic acid to the clitoris. And even its removal. Was John Kellogg the only person like this of his time, or was this more widespread? It was more widespread, and I would say that he was one of the most prominent ones. There was another huge player that played a role in the birth of the modern wellness industry: He was a guy named Bernarr MacFadden, who some consider the 20th century's first celebrity health influencer. This guy was equally eccentric to John. Macfadden would strut around New York barefoot so that his soles could absorb the earth's energy, and he would sleep on the floor so that his energy would align with the earth's natural magnetic rhythm. And he was very hostile to vaccines. So you're telling me that an anti-vaxx wellness influencer is not a new phenomenon. Very old, over a century old. Similar to Kellogg, you know, Macfadden would also sell this idea of health as a moral virtue, where it's all about virtuous eating. It's all about virtuous exercise. And the problem with these ideas is that health is not a moral virtue. What these ideas do is they promote an idea about health that ignores the science. And then they downplay the role of other important things that we know play a role in health, like genetics, social factors, and just plain old bad luck. It's very interesting that all of this happened in the 19th century. I think of that as a time with a lot of advancements in science and in health. Totally. Around the same time that these wellness ideas were percolating, there was also something called the Flexner Report of 1910, and that really ushered in the dawn of modern medicine. What that report did was it essentially wanted medicine and medical schools to get their act together and make them much more scientific. It would encourage schools to either get rid of alternative medicine from their curriculum or just shut these schools down altogether. At the same time, [the report] really disadvantaged folks who were economically underprivileged. And what that did is it opened [a space] for alternative medicine or wellness to step in and to take on the role of listening, humanizing, and comfort. What about the term wellness specifically, though? When did that officially become a thing? Some consider the father of the modern wellness industry to be Halbert Dunn. He was a biostatistician, and he first used the term wellness as we use it today, publishing an article in the Canadian Journal of Public Health in 1959. What Dunn did is he distinguished good health, which he defined as freedom from illness, from what he dubbed high-level wellness, which is a kind of optimal functioning in one's environment. And I think his definition was quite thoughtful, but it really didn't stick.
