Flight attendants never forget the first time they see themselves in uniform. It’s one of the most exciting moments of their career, even when the uniform is hideous.


The first airline I worked for was a low-cost carrier: Sun Jet International Airlines. I was 24, which might explain why I thought I looked great in my white button-down blouse, two silver stripes adorning each shoulder, tucked into pleated, navy blue Bermuda shorts with navy blue hose and heels. Let me repeat: pleated shorts. With heels. I loved the ridiculous getup. After all, it showed I was a flight attendant! The snap-on tie didn’t even bother me (until I spotted a woman working at the Nathan’s hot dog stand at Newark Airport wearing the same snap-on). But that’s another story.

Now imagine how I felt a year later when a major carrier hired me as a flight attendant. In training, when I stood in front of the mirror for the first time in the new uniform, I almost pinched myself to make sure I wasn’t dreaming. I nearly broke down and cried, that’s how happy I was. I could have kissed each and every one of my instructors that very moment. Even though they scared me. Even though the cost of the uniform ($800) would be payroll-deducted from my first couple of paychecks.

Flash forward 20 years and imagine how excited I was when American Airlines announced we were getting new uniforms. Oh my gosh, I couldn’t wait.

Well now, five months later, that exciting new uniform is in a garbage bag that’s in a tub that’s in the basement of the building I stay in when I’m in New York to work. It’s marked “Evidence.” Now I wear look-alike pieces made by Calvin Klein, bought and paid for by yours truly.

My uniform makes me sick (literally).

Why? I’m not sure. I have a few theories, but since I can’t prove any of them, I can only say that before the new uniform I felt great. Now I feel horrible every time I go to work. Since the uniform debuted on September 20, I’ve seen more doctors than I’ve ever seen in my life, and I’ve learned things about toxic chemicals I never knew before. Before the new uniform I didn’t know what “sensitizers” were or what “synergy” meant, and I sure as heck would have never dreamed I’d develop multiple chemical sensitivity. Now I’m practically an expert on the subject.

Before the new uniform, I had no idea there was a group at Harvard studying flight attendants in relationship to endocrine disruptors, and if I had, I wouldn’t have cared. Now I beg them to study me. They have a paper coming out focusing on uniforms and flight attendant health next month. I can’t wait to read it.

But let’s talk about what it’s like to wear a uniform. If I were to wear retail clothing the way I wear a uniform, it would fall apart in a year. Uniforms are made to last. That’s why they’re subjected to testing that’s totally different from retail clothing, and why they’re treated with so many chemicals. The chemicals not only make them last longer than retail clothing, but they also make them look good. There’s a reason why I can wipe tomato juice off my skirt and why my shirts barely wrinkle.

The big difference between retail clothing and a uniform is you’re required to wear a uniform to work every time you go to work, which means you wear certain pieces of clothing more in a month than most people wear in a year. This is what makes it easier to pinpoint a problem with the clothing industry.

If I were to wear a sweater on a day off that made me feel sick, I’d just think I might be coming down with something. But with a uniform you realize that you only feel bad when you’re wearing the uniform. You might notice that you have a persistent dry cough at work, but not at home. When the uniform is on, you feel nauseous. But then you take it off and you feel fine. You never get a nosebleed when you’re out of uniform, only when you’re in uniform. Eventually, you connect the dots. You bag up the uniform and bury it in your backyard. Your neighbor’s backyard.

It took me two months to realize my health issues might be related to my new uniform. I don’t know if I would have figured it out so quickly if I hadn’t been reading up on what had happened to the Alaska Airlines flight attendants who had the same issues with their uniforms that were made by the same manufacturer. (They have since been recalled.) After three months in uniform I became positive my health issues were related to what I was required to wear to work.

It started with thyroid issues. After six days in uniform my TSH (thyroid stimulating hormone), which had been stable for years, was out of the normal range. (I get my blood tested every three months.) My doctor upped my dosage of medication and I stopped wearing the official uniform and started wearing my fake Calvin Klein uniform. Problem solved, I thought.

Wrong.

[quote position=”full” is_quote=”true”]Four months after we were issued the new uniforms my heart started racing.[/quote]

Four months after we were issued the new uniforms my heart started racing. At first I wondered if it was anxiety. I wondered what it was that made me feel so anxious as soon as I got to the airport? Was it the fact that I had just started flying more international trips? Was I anxious about my crews? It didn’t make sense because I love flying to Europe and I always enjoy being around the people I work with.

Then I realized my heart was racing—not because I was stressed out or anxious, but because my coworkers in uniform were nearby. I’m not sure if I would have figured that out if the cough hadn’t started at the same time. Nonstop all flight. Away from colleagues in uniform I was fine. Near them I can’t stop coughing.

Respiratory issues followed next. Five months after the new uniform was released,I found myself short of breath at work. My lungs felt like they had shrunk. I ended up in the emergency room in December. I was diagnosed with RAD (reactive airway disease) and was given an inhaler and steroids. In January I broke out in hives. I haven’t been to work since. I wanted to give myself a little time to recover. My first trip is next week. I’m a little scared to see what February brings.

So far, thousands of my colleagues have had a “reaction”. Some have respiratory problems; others have wicked rashes and skin irritations; others have debilitating fatigue.

[quote position=”right” is_quote=”true”]My lungs felt like they had shrunk.[/quote]

Workers’ compensation cases are denied because this is considered an “allergic reaction.” In workers’ comp world, an allergic reaction is personal and, therefore, has nothing to do with the job. Never mind the job requires us to wear a uniform that made us sick. OSHA refuses to get involved because the airline has dealt with the uniform crisis by allowing us to wear the old uniform or our own look-alike pieces. In their minds the problem is solved. I’m here to tell you it’s not. Coworkers who are still wearing the new uniform make us sick.

The company is adamant that can’t happen. And yet it does happen. It is happening. To me and thousands of others. Now some flight attendants (rampers and customer service agents too) are out of sick time and are borrowing money from family or friends. Some are being harassed by managers due to their poor attendance and have been threatened with being fired.

Meanwhile the company continues to remind us they’ve spent over a million dollars to test the new uniform—to prove it’s safe. They’ve tested it three times already, and each time the test result comes back the same: safe. Never mind the 3,000 sick flight attendants. I have no idea how many pilots, customer service agents, or rampers have had reactions. All I know is 1 out of 10 flight attendants have been affected. I should say 1 out of 10 flight attendants have reported they’ve been affected. Many choose to suffer in silence.

I’ve been sharing my story on social media. A journalist sent me a link to a story about the women who painted watch dials with radium — women who worked with and were sickened by radiation. They too were told it was safe — until their numbers made it impossible to deny it wasn’t safe.

Remember when scientists claimed asbestos was safe?

[quote position=”left” is_quote=”true”]Remember when scientists claimed asbestos was safe?[/quote]

That’s the problem with big business. Big brands make a lot of money from cheap clothes. It’s in their best interest to keep the public in the dark, to keep repeating everything is A-ok—even when it’s so glaringly not ok.

“Where’s the data, the proof?” I keep hearing.

I’m the data. I’m the proof. ME. I’m the lab rat. Too bad I’m not enough. Too bad more of my coworkers will have to get sick before anyone will take it seriously. Meanwhile those of us who have already had reactions will continue to get worse.

“I’m not contagious,” I’m always telling coworkers as I cough uncontrollably while at work. “It’s the uniform.” I went through an entire bag of cough drops on my last flight. During the beverage service I had two in my mouth at the same time just so I wouldn’t cough all over passengers when I asked them what they’d like to drink.

Many of my coworkers don’t believe me. They don’t believe it’s the uniform. Even when they’re scratching or coughing or complaining about any of the other numerous symptoms I’ve listed above. I don’t blame them. It’s kind of crazy to think your clothes could be poisoning you.

Meanwhile the chemicals continue to build up in our system. It takes some people longer than others to have a “reaction.” It can be hives or a rash or it can be worse. Some people feel extremely fatigued, others have bloody noses, eye infections, or they become nauseous. Others get terrible sinus infections. After the third round of antibiotics they might connect the dots. It usually takes another reaction on top of the first reaction to figure it out. You see, once you have a reaction you don’t get to have the same reaction. It gets worse as you absorb more chemicals. Then all the chemicals you’ve absorbed begin to affect you on your days off.

Now I get winded walking the dog. I’ve been doing cardio five days a week since college. Walking the dog didn’t bother me until two months ago. Once toxic chemicals build up in your system you become extremely sensitive to chemicals in the environment. Then you develop what’s called multiple chemical sensitivity. Google it. Now I only buy fragrance-free products.

There are so many toxic chemicals in fragrance. Did you know that? I didn’t either … until now.

The other night someone I know started vaping. Right away I began to have the same reaction I have when I’m around coworkers who are wearing the new uniform. My chest felt tight. When I said something to him, he swore it was safe. “It’s only glycerin, steam and fragrance.”

I could tell by my reaction it wasn’t safe. I could tell by my reaction something in the vapor is also in my uniform. I did a little research. Formaldehyde (among other things.)

Formaldehyde is an eye irritant. (It’s also an endocrine disrupter. I’ve learned so much in the last three months). Last night my eye started watering. This morning it was so swollen it looked as if a bee had stung me. I’ve never had a reaction to vaping before — or to a uniform — until now.

[quote position=”full” is_quote=”true”]I shouldn’t have to be a human guinea pig.[/quote]

The point, is the uniform is affecting my life — at work and at home. The uniform has changed me forever. I’ve stopped burning candles and I’m afraid to wear perfume — things I used to love! Now I dread going to work. I love my job, but my job is making me sick.

Mark my words the uniform is going to cause long-term health issues for a lot of people. I pray I’m not one of them. Right now we don’t need lawyers to fight this; we need scientists and chemists to figure out what the hell is going on. I shouldn’t have to be a human guinea pig. Flight attendants shouldn’t have to prove there’s a problem with the garment industry, but we will — by suffering.

Which brings us to that word synergy — and testing. The proof. The data. Maybe one uniform piece tests safe, but all of it worn together is unsafe. Chemicals on top of chemicals. Layers upon layers of chemicals. Then mix in the chemicals we come into contact on the airplane that are in the carpets and seats: flame retardants and more formaldehyde. Remember a flight attendant wears a uniform all day and that day can be 10–12 hours long. Mix in body heat that releases the chemicals and opens the pores so you absorb more chemicals.

Now add in a little recycled air and a flying tube packed with passengers who are warm and wearing their own chemicals. That might explain why flight attendants were quicker to react and to have more severe reactions than other people at my airline, like gate agents, who are wearing uniforms made by the same manufacturer. Or maybe it’s just a batch issue. The uniforms come from multiple countries. Mine were labeled Bangladesh, China, Sri Lanka.

The scary part is not knowing what the hell is happening.

[quote position=”right” is_quote=”true”]The scary part is not knowing what the hell is happening.[/quote]

It’s not just my airline. I’ve written about the uniforms before. Since then I’ve received numerous emails from flight attendants who work for other airlines who are having similar issues with uniforms made by the same manufacturer. And I’m not just talking about Alaska Airlines, which faced similar accusations by flight attendants in 2012 who said uniforms were making them sick. I’m talking about regional carriers and a Canadian carrier.

What’s even more frightening is this isn’t just happening to flight attendants. Last week one of the many doctors I’ve seen in the last three months sent me to a lab to give blood. The woman who took my blood wanted to know why I was giving so much blood. I told her about the uniforms. She told me about her lab coat. She said their lab coats were a problem for some of her coworkers who were “allergic” to the chemicals they treat it with to make it water resistant. “So we can wipe things off.”

UPS has had problems too.

This is bigger than us, bigger than a uniform problem. But we can pinpoint a problem easier because we wear these uniforms every day and therefore we’re a little more in tune to how they make us feel.

When I shared a photograph of a flight attendant who had what looked like a chemical burn all over her face on Facebook, an old high school friend I haven’t heard from in 20 years reached out and shared a photograph of her young daughter who had the same reaction on her face. “We were able to narrow the problem down to an outfit because she wore it three times and it happened every time she wore it,” my friend wrote. “We threw it away and she hasn’t had a reaction since. But she has sensitive skin.”

Sensitive skin. Before the uniform I didn’t have sensitive skin. Now I have sensitive skin. Funny how that works.

In a private Facebook group for airline employees, a few coworkers keep saying the uniform is safe simply because it tested safe. I remember when I first heard about the Alaska Airlines flight attendants when they started having reactions and blowing it off. Unless it’s happening to you and you’re following other people’s stories about their reactions and you’ve done a good deal of research, it’s easy to believe the uniform is only a problem for some people.

It’s easy to believe we’re just feeling a little itchy and we should figure out a way to suck it up and deal with it. But it’s so much worse than having to pop a little more Claritin and an entire bag of cough drops. I tried to explain to one of the coworkers that there’s something wrong with the testing, that the environment matters, that the chemicals take time to build up, but she wouldn’t hear it. Finally she said, what are you going to do HEATHER POOLE if they don’t recall the uniform? (She wrote my name in caps like that)

Quit. I’ll have no choice but to quit a job I love.

That doesn’t seem right.

  • Photographic memory is a myth – here’s what research really says about remembering
    Photo credit: F.J. Jimenez/Moment via Getty ImagesYour memory is not a camera.

    Hollywood loves a superpower. Not all involve capes or cosmic rays. Some are cognitive: characters who can remember everything. In movies and on TV, viewers repeatedly encounter those with extraordinary minds who glance once at a page, a room or a face – and later recreate every detail with surgical precision.

    You see it everywhere: “Suits,” “Sherlock” and “The Girl with the Dragon Tattoo.” Even in children’s literature there’s fifth grader Cam Jansen, who activates her photolike memory by saying “Click!”

    Most recently, it appeared in the television series “The Pitt,” set in a hospital emergency department. When the digital patient board suddenly went offline, medical student Joy Kwon saved the day by effortlessly reciting from memory every lost detail – names, rooms, doctors, conditions, vitals. It’s a gripping moment. The stakes are high, recall is perfect, and the implication is clear: Some people have minds that function like high-resolution cameras.

    The idea of photographic memory is simple and powerful: Experience is captured objectively, stored completely and retrieved perfectly. See it once, keep it forever.

    There’s just one problem. There’s no scientific evidence it exists.

    Your memory doesn’t record, it reconstructs

    As a memory researcher, I understand that belief in photographic memory is common and the idea is compelling. But it is simply wrong.

    Human memory does not work like a recording device. It’s a reconstructive process even among those with the most extraordinary skills. When you recall an event, memory doesn’t just hand you your experiences the same way every time. It’s never a matter of simply accessing, retrieving and playing back a static record of a stored slice of the past.

    Rather, you reconstruct the past by piecing together the remnants of experience available to you in the moment of recollection. It’s a process shaped by a range of factors, including the search cues you use; your present knowledge, attitudes and goals; and your current state of mind or mood.

    Because each of these factors is dynamic and changing, you’ll remember the past differently today – if ever so slightly – from how you remembered it yesterday, and differently from how you’ll remember it tomorrow. What you remember is not only incomplete but also inexact.

    A closer look at extraordinary memory

    Some people, such as memory competition champions, do have extraordinary memories. They can memorize thousands of digits or entire decks of cards in minutes. Their feats are real, but they don’t come from a memory that takes mental snapshots.

    Instead, these people rely on strategies – mental frameworks built through thousands of hours of deliberate practice to scaffold their memory in specific domains. Without these strategies and in other aspects of life, their recall looks pretty much like everyone else’s. Experts’ performance reflects better methods, not different machinery.

    In the scientific literature, the ability that comes closest to photographic memory is eidetic imagery: a form of visual mental imagery in which people claim they can briefly continue to “see” pictures they carefully studied and that are then removed from view.

    This ability is rare, is seen mostly in children, and usually disappears by adolescence. Even at its peak, however, it falls short of the Hollywood ideal. Eidetic images fade quickly and are not perfectly accurate. They can include distortions and even details that were not seen.

    It’s exactly what you’d expect from a reconstructive memory system – and exactly what you would not expect from a literal recording.

    Forgetting is a feature and not a flaw

    The myth about photographic memories feeds into the idea that your memory has failed if you can’t remember – that if your memory worked right, it would operate like a camera. When you can’t retrieve information or you lose it entirely, it can feel like something has gone wrong.

    In reality, forgetting is functional. Without it, we’d never get by.

    For instance, people use their memories of the past to forecast the future. Perfect memory would be a liability. Forgetting washes out the details of specific episodes and retains the gist so you can apply past experiences to novel situations, not just those that exactly match what happened before.

    Forgetting also guards your emotional health. The dulling of memories for negative events, like say an embarrassing episode, makes it easier for you to move on than if you reexperienced all the details in full force every time the event came to mind.

    Forgetting protects your sense of self as well. Memories of your past form the foundation of your identity. To help maintain a stable self-concept, people selectively modify or even forget those memories that challenge their views of themselves.

    The rare individuals who come closest to having near-perfect memory often reveal the downsides. People with highly superior autobiographical memory can remember nearly every day of their lives in vivid detail. If you ask one of these people to recall what they did on Nov. 24, 1999, they likely can tell you.

    Their extraordinary ability seems to come from a habitual, even compulsive, reflection on their past and a focus on anchoring memories to dates. However, this skill is limited to autobiographical events, and they are prone to various kinds of memory distortions and errors just like everyone else.

    While this ability might sound like an advantage, many people with highly superior autobiographical memory describe it as exhausting. They struggle to move past negative experiences because their memories make them seem as sharp as ever.

    Accurate – and empowering – view of memory

    Beliefs about “perfect memory” shape how people judge studentseyewitnessespatients and even themselves. They influence legal decisions, educational practices and unrealistic expectations about what human minds can – and should – do.

    Letting go of the camera metaphor could be a step toward better understanding how memory works. The brain is not a roll of film, it’s a storyteller – one that edits, interprets and reshapes the past in light of the present.

    And that’s not a limitation. It’s a superpower.

  • How workplace stress hijacks the nervous system to cause headaches − and a neurologist’s guide to managing them
    Photo credit: Sean Gladwell/Moment via Getty ImagesOngoing stress can send the nervous system into a state of heightened sensitivity.

    Many people finish the workday not just tired but wired. Their mind keeps racing, their body feels tense, and even in moments that should be restful they feel a lingering sense of urgency. Conversations replay in their mind, unfinished tasks resurface, and their nervous system seems unwilling to power down.

    You may recognize this experience. It has become so common that it is often accepted as the norm in modern professional life. Yet this persistent state of activation carries consequences for physical health, especially for people prone to headaches.

    As a board-certified neurologist who specializes in headache medicine, I see a lot of patients whose pain increases from the high-pressure work culture prevalent today. While it might seem beyond your control, there are some steps you can take.

    Stress and the nervous system

    Stress is not inherently harmful. In fact, when experienced in short bursts, stress can be beneficial by increasing focus, improving performance and preparing the body to handle challenges. However, problems arise when stress becomes chronic and relentless.

    The nervous system perceives and processes both stress and pain. Built to be highly adaptable, it continually responds to internal signals and external factors, constantly recalibrating to maintain balance. When the brain continuously perceives ongoing demands without adequate recovery, it keeps the body in a prolonged state of alertness.

    During these periods of ongoing stress, hormones such as cortisol and adrenaline remain persistently elevated. In this sensitized state, signals that would typically be ignored or interpreted as minor can start to feel much more intense.

    This state leads to an increase in heart rate and sustained muscle tension, with the nervous system transitioning into continuous fight or flight mode. In the context of headaches, this sensitization can lower the threshold for pain, making it easier for a headache to start and harder for it to stop.

    Over time, this constant activation can disrupt the body’s natural balance and create an environment for headache disorders to develop or worsen.

    Chronic stress acts as both a trigger and an exacerbating factor for migraines. The neurological system of people who experience migraines is comparatively more responsive to environmental changes, including variations in sleep patterns, the environment, hormonal fluctuations and stress intensity.

    This means that persistent exposure to stress may drive up frequency and severity of migraine episodes. In addition, muscle tension in the neck, shoulders and scalp – a frequent effect of stress – can cause tension headaches, too.

    Extended periods of sitting, sustained concentration and physical tension during the workday can contribute to the development of tension headaches in the later hours of the day.

    Poor sleep, too much desk time and other factors can exacerbate the effects of stress on the nervous system, leading to headaches. ChadaYui/iStock via Getty Images Plus

    The role of sleep

    Chronic stress can also have a profound impact on sleep quality. Many people who feel persistently wired at the end of the workday struggle to fall asleep or stay asleep. That fitful sleep may lack the restorative qualities necessary for recovery.

    Poor sleep can, in turn, perpetuate the stress cycle, leaving the brain further sensitized and increasing the likelihood of headaches the following day. This loop can be difficult to break, as fatigue reduces resilience and amplifies the sense of being overwhelmed that comes with stress.

    In addition to affecting sleep, chronic stress impairs concentration and cognitive function. When the brain remains in a state of constant vigilance, scanning for demands and threats, it becomes harder to focus, be creative and solve problems. As a result, productivity declines, errors become more frequent and frustration mounts, adding to the overall stress burden.

    Headaches that occur alongside these cognitive challenges can further disrupt daily life, making even routine tasks feel difficult.

    Managing work stress

    Understanding the connection between stress and the nervous system points to some steps you can take to shift the nervous system out of its constantly activated state. You’ll never eliminate stress entirely – that’s neither realistic nor necessary. But it is possible to create intentional space for the body to reset:

    Small, consistent strategies that address both biological and lifestyle causes of headaches can minimize the effects of chronic stress and encourage nervous system regulation. Over time, these strategies can gradually reduce headache frequency and severity, improving overall quality of life.

  • Pollen allergies are brutal this year – a doctor explains why, and how to find relief
    Photo credit: Science Photo Library/Getty ImagesSneezing, wheezing … it’s allergy season.

    Spring means beautiful flowers, fragrant lilacs – and lots of tree pollen coating cars and setting off sneezing, wheezing and headaches.

    As an allergist and immunologist at the University of Colorado School of Medicine, I help patients with seasonal allergies and associated allergic diseases manage their conditions, and one question comes up year in and out: Will this season be worse than last year?

    With a record warm start to spring 2026 in much of the U.S., the answer is a teary-eyed “yes.”

    What are allergies?

    More than 1 in 4 U.S. adults suffer from seasonal allergies. That number is expected to increase as climate change results in longer and more intense pollen seasons.

    When someone talks about having allergies, they are referring to a condition called allergic rhinitis or allergic conjunctivitis – inflammation of the nose or eyes related to allergen exposure. This results in itchy, watery eyes, runny nose, sneezing, congestion and nasal passage itching. They show up when allergens are in the air, during spring, summer and fall.

    The big driver of seasonal allergies is a protein in pollen. Pollen is the male reproductive material that plants release to spread their species.

    Those pollen proteins become problems when the immune system develops an allergic antibody known as IgE to these proteins. When several IgE molecules bind to the allergen when it lands on the tissues of the eye or nasal passages, the cells release molecules such as histamine, prostaglandins and leukotrienes. These molecules interact with blood vessels and nerves to trigger the symptoms that allergy sufferers know all too well.

    Which pollens cause allergy symptoms?

    Pollen season starts with the trees.

    In late winter and early spring, trees begin releasing pollen in many places in the United States. Not all trees follow this schedule – mountain cedars, or juniper trees, for example, can release clouds of yellow pollen from November through January in Texas, causing a condition known as cedar fever.

    As the year progresses, grasses will emerge and their pollen will cause symptoms through most of the summer – typically April to July.

    Then ragweed and other weeds release pollen that causes symptoms into the fall until a freeze stops their pollen production.

    What makes one pollen season worse than others?

    Several factors can influence how bad a season can be when it comes to seasonal allergies. The two big ones are the length of the growing season and the amount of pollen in the air. Both are expanding.

    Over the past several decades, as global temperatures have risen, the growing season has lengthened in many parts of North America. Once temperatures begin to be above about 40 degrees Fahrenheit (4 Celsius), trees will begin to emerge from dormancy.

    That’s what the Western U.S. saw in 2026, as an unprecedented warm spring drove the early emergence of tree pollen. In some locations, growing season is two weeks longer on average than in the 1990s and more than four weeks longer than in the 1970s.

    Another factor driving pollen production is the increase in atmospheric carbon dioxide, largely from the burning of fossil fuels. Higher carbon dioxide levels increase plant growth, leading to longer pollination periods and more pollen produced by plants. With higher pollen counts, more people can develop symptoms. Consequently, I have been seeing more patients who are experiencing allergies for the first time.

    Windy days can also blow pollen into the air and spread it over a wider area.

    Rain and humidity can affect pollen counts as well. Rain can temporarily scrub pollen from the air. But humidity and moisture after the rain will result in ruptured pollen granules, resulting in pollen that is easier to carry on the wind and breathe in. This is particularly the case with grass pollen.

    So, how can you avoid allergy symptoms?

    There are many ways to manage allergy symptoms.

    The first is to try to avoid the allergen by making changes in your home to reduce exposure. Keeping windows closed during the pollen season will reduce the amount of allergen that can enter your home. Wiping down pets with a damp towel can reduce the amount of allergens they bring in. Avoiding using clotheslines can reduce pollen levels on washed items.

    Changing clothes or showering after being outdoors can reduce the amount of allergens that remain on you.

    Using HEPA air purification in the home can reduce household allergen levels. Look for non-ionizing air purification; ionizing air filters can generate ozone, which worsens indoor air quality.

    To know when allergens are getting worse outside, watch the pollen forecast from the National Allergy Bureau. As a general rule, pollen counts are highest in the morning. However, outdoor air pollutants can increase in the afternoon when pollution, including particulate matter (PM2.5) and ozone, reach peak levels in the midday and afternoon heat.

    Do medications work?

    Medications can help alleviate symptoms. A saline nasal rinse can reduce mucus and allergens inside the nasal passages. For mild symptoms, daily nonsedating, or second-generation, antihistamine can be effective.

    Daily use of nasal steroids can be helpful for people with moderate to severe allergies, but they can take several weeks to reach peak effect. A nasal antihistamine spray can provide additional benefits.

    Antihistamine eye drops can also be helpful. In a dry climate like Colorado’s, nasal dryness can contribute to congestion, so using nasal hydration such as saline sprays can ease symptoms.

    If medications don’t help, you could speak with an allergist about the possibility of immunotherapy – allergy shots – but they require weekly and monthly shots over several years. While allergy shots are effective at reducing allergy symptoms and the need for medications, they do have side effects, such as local site reactions and asthma symptoms, and they may trigger a severe allergic reaction called anaphylaxis.

    Allergies can be miserable but manageable – even in an overproductive year like much of America is seeing in 2026. Understanding what’s causing them and finding the right solutions for you can make it easier to enjoy those flowers and walks in the sunshine.
