What allergies are high today in chicago
The most common allergen is pollen, a powder released by trees, grasses and weeds that fertilize the seeds of neighboring plants. As plants rely on the wind to do the work for them, the pollination season sees billions of microscopic particles fill the air, and some of them finish up in people’s noses and mouths.
Spring bloomers include ash, birch, cedar, elm and maple trees, plus numerous species of grass. Weeds pollinate in the tardy summer and drop, with ragweed being the most volatile.
The pollen that sits on brightly colored flowers is rarely responsible for hay fever because it is heavier and falls to the ground rather than becoming airborne.
Bees and other insects carry flower pollen from one flower to the next without ever bothering human noses.
Mold allergies are diverse. Mold is a spore that grows on rotting logs, dead leaves and grasses. While dry-weather mold species exist, numerous types of mold thrive in moist, rainy conditions, and release their spores overnight. During both the spring and drop allergy seasons, pollen is released mainly in the morning hours and travels best on dry, warm and breezy days.
What can I do if my allergy meds aren’t working…or my allergies are getting worse?
If you’re already taking OTC allergy meds (and, you know, keeping your windows closed and washing your face and hair after coming inside), allergy shots, a.k.a.
allergen immunotherapy, make your immune system less reactive to allergens (read: pollen), and for some people, they can even induce a cure, says Dr. Parikh.
“By giving little increasing doses of what you are allergic to, you train the immune system to slowly stop being as allergic,” she says. “This is the best way to address allergies, as it targets the underlying problem and builds your immunity to a specific allergen.”
The downside? Allergy shots are a bit of a time commitment.
You’ll need to get them once a week for six to eight months, then once a month for a minimum of two years, says Dr. Parikh.
You need to be a little bit patient, too, because it can take about six months to start feeling better (so if you desire protection by March, you’ll probably own to start in September the year before). But a life without allergies? Sounds worth it to me.

About a third of Americans live in areas where allergies could be made worse by a combination of high ozone levels and ragweed pollen, according to a new report.
The top cities with this allergy-inducing combo — dubbed in the report as the "Sneeziest and Wheeziest" cities — include Richmond, Virginia; Memphis, Tennessee; Oklahoma City; Philadelphia; Chattanooga, Tennessee; and Chicago, according to the report, from the Natural Resources Defense Council (NRDC), an environmental advocacy group based in New York.
The report is one of the first to identify the areas that own both high ozone levels and ragweed pollen.
Overall, 109 million Americans live in these areas, the report found. Either ozone smog or ragweed pollen by themselves can trigger allergy symptoms and asthma attacks, but people who are exposed to both tend to become more ill than people who are exposed to only one of these triggers, the NRDC says.
What’s more, the rising temperatures expected to come with climate change could increase both ozone production and pollen levels, worsening people’s allergies, the NRDC says. Other cities that made the top-10 list of the Sneeziest and Wheeziest were Detroit; New Haven, Connecticut; Allentown, Pennsylvania; and Atlanta.
"Millions of us are sneezing and wheezing from allergies and asthma worsened by climate-change-fueled ragweed pollen and ozone-smog pollution," said study co-author Juan Declet-Barreto, a fellow in the Climate and Clean Air program at NRDC.
"This double-whammy health threat will only intensify, and affect more people, if we don’t take steps to reduce climate change now," Declet-Barreto said. [9 Myths About Seasonal Allergies]
Ragweed pollen is a common trigger of seasonal allergy symptoms, which can include sneezing, runny nose and itchy eyes. Rising carbon dioxide levels and temperatures could cause plants, including ragweed, to produce more pollen, and for longer periods.
Studies own found that ragweed plants grow bigger and produce more pollen when carbon dioxide levels rise, the NRDC says.
Exposure to ozone, a component of smog, can irritate the lungs and worsen asthma and allergy symptoms. Warmer temperatures also enhance the chemical reactions that form ozone, and studies propose that climate change could also increase ozone concentrations, the NRDC says.
The new report found that there were 275 U.S. counties that had at least one day of unhealthy ozone conditions, and had ragweed in the area. The NRDC’s rankings also took into account information from the Asthma and Allergy Foundation of America and the American Lung Association.
"Together, the ragweed pollen and ozone can interact to worsen respiratory health, making these areas especially vulnerable to a climate change–related rise in allergic and respiratory disease," the report says.
Rohit Katial, program director of allergy and immunology at National Jewish Health in Denver, who was not involved with the report, agreed that the combination of high ozone levels and ragweed can make allergy symptoms worse than can either factor alone.
"You get sort of a double hit. It makes your respiratory symptoms worse," Katial said.
But Katial disagreed that certain areas of the United States would experience more of an allergy boost than others as a result of climate change.
"I ponder it would happen everywhere," Katial told Live Science. He pointed out that other plants besides ragweed could increase pollen production due to global warming, so people allergic to these plants could experience worsening allergies in areas where ragweed does not grow.
The new report focused on ragweed because it is a well-known trigger of allergy symptoms, the NRDC said.
To reduce the health effects of climate change, the NRDC recommends that the Environmental Protection Agency strengthen the limits on carbon pollution from power plants, and lower the allowable level of ozone in the air.
The government should also improve the way it tracks pollen levels, the NRDC says.
For the public, the NRDC recommends that people hold track of pollen counts in their areas, and hold doors and windows closed on especially high-pollen or high-ozone/smog days. People should also avoid strenuous outdoor activities on days with high ozone levels, or act out these activities in the morning when ozone levels and pollen counts are lower.

Itchy eyes, a congested nose, sneezing, wheezing and hives: these are symptoms of an allergic reaction caused when plants release pollen into the air, generally in the spring or drop. Numerous people use hay fever as a colloquial term for these seasonal allergies and the inflammation of the nose and airways.
But hay fever is a misnomer, said Dr. Jordan Josephson, an ear, nose and throat doctor and sinus specialist at Lenox Hill Hospital in New York City.
«It is not an allergy to hay,» Josephson, author of the book «Sinus Relief Now» (Perigee Trade, 2006), told Live Science.
«Rather, it is an allergy to weeds that pollinate.»
Doctors and researchers prefer the phrase allergic rhinitis to describe the condition. More than 50 million people experience some type of allergy each year, according to the Asthma and Allergy Foundation of America. In 2017, 8.1% of adults and 7.7% of children reported own allergic rhinitis symptoms, according to the Centers for Disease Control and Prevention (CDC). Worldwide, between 10 and 30% of people are affected by allergic rhinitis, Josephson said.
In 2019, spring arrived early in some parts of the country and later in others, according to the National Phenology Network (NPN).
Spring brings blooming plants and, for some, lots of sneezing, itchy, watery eyes and runny noses. According to NPN data, spring reared its head about two weeks early in areas of California, Nevada and numerous of the Southern and Southeastern states. Much of California, for example, is preparing for a brutal allergy season due to the large quantity of winter rain.
On the other hand, spring ranged from about one to two weeks tardy in the Northwest, the Midwest and the Mid-Atlantic U.S. [Watch a Massive ‘Pollen Cloud’ Explode from Late-Blooming Tree]
Tests & diagnosis
A physician will consider patient history and act out a thorough physical examination if a person reports having hay-fever-like symptoms. If necessary, the physician will do an allergy test. According to the Mayo Clinic, people can get a skin-prick test, in which doctors prick the skin on a person’s arm or upper back with diverse substances to see if any cause an allergic reaction, such as a raised bump called a hive.

Blood tests for allergies are also available. This test rates the immune system’s response to a specific allergen by measuring the quantity of allergy-causing antibodies in the bloodstream, according to the Mayo Clinic.
How do scientists know how much pollen is in the air? They set a trap. The trap — generally a glass plate or rod coated with adhesive — is analyzed every few hours, and the number of particles collected is then averaged to reflect the particles that would pass through the area in any 24-hour period.
That measurement is converted to pollen per cubic meter. Mold counts work much the same way.
A pollen count is an imprecise measurement, scientists confess, and an arduous one — at the analysis stage, pollen grains are counted one by one under a microscope. It is also highly time-consuming to discern between types of pollen, so they are generally bundled into one variable. Given the imprecise nature of the measurement, entire daily pollen counts are often reported simply as low, moderate or high.
The American Academy of Allergy, Asthma & Immunology provides up-to-date pollen counts for U.S.
What does that mean for my allergy meds? When should I start taking them?
There’s no point in waiting until you’re miserable to take allergy meds, especially if you desire to hold up your outdoor workouts.
In fact, allergists recommend you start taking meds a couple weeks before allergy season arrives, or, at the latest, take them the moment you start having symptoms, says Dr. Parikh.
Taking them early can stop an immune system freak-out before it happens, lessening the severity of symptoms, he adds. Check out the National Allergy Map to figure out when to start taking meds depending on where you live.
As for which allergy meds to take, if you’re seriously stuffed, start with steroid nasal sprays such as Flonase or Rhinocort, which reduce inflammation-induced stuffiness, says Dr.
Keet. And if you’ve got itching, sneezing, and a runny nose, too, glance for non-sedating antihistamines such as Zyrtec, Xyzal, or Allegra, she adds. Just remember: While OTC allergy meds suppress symptoms, they don’t cure the problem, so they may be less effective if your allergies are worsening, notes Dr. Parikh.
Okay, so when does allergy season 2020 start?
Well, it’s technically *always* allergy season due to year-round offenders such as dust mites, mold, and pet dander, says Purvi Parikh, MD, an allergist and immunologist with Allergy & Asthma Network.
But some allergens–pollens, specifically—are seasonal.
Tree pollen, for example, pops up in the spring (generally in tardy March to April), grass pollen arrives in the tardy spring (around May), weed pollen is most prevalent in the summer (July to August), and ragweed pollen takes over from summer to drop (late August to the first frost), says Dr.
And even worse news: Climate change means allergy season begins earlier and lasts longer, adds Corinne Keet, MD, PhD, a professor and allergist at Johns Hopkins University School of Medicine.
To get super-specific, Pollen.com has a National Allergy Map that provides an up-to-date allergy forecast in diverse areas around the country and an Allergy Alert app that gives five-day forecasts with in-depth info on specific allergens, helping you decide if you should stay indoors that day.
Certain areas own also seen a particularly large increase in pollen during allergy season. In 2019, the New York Times reported on the extreme blankets of pollen that hit North Carolina; Georgia and Chicago also faced especially aggressive allergy seasons too.
In Alaska, temperatures are rising so quickly (as in numerous other far northern countries), that the pollen count and season duration are seeing unprecedented growth.
The symptoms of allergic rhinitis may at first feel love those of a freezing. But unlike a freezing that may incubate before causing discomfort, symptoms of allergies generally appear almost as soon as a person encounters an allergen, such as pollen or mold.
Symptoms include itchy eyes, ears, nose or throat, sneezing, irritability, nasal congestion and hoarseness. People may also experience cough, postnasal drip, sinus pressure or headaches, decreased sense of smell, snoring, sleep apnea, fatigue and asthma, Josephson said.

Many of these symptoms are the immune system’s overreaction as it attempts to protect the vital and sensitive respiratory system from exterior invaders. The antibodies produced by the body hold the foreign invaders out, but also cause the symptoms characteristic of allergic responses.
People can develop hay fever at any age, but most people are diagnosed with the disorder in childhood or early adulthood, according to the Mayo Clinic. Symptoms typically become less severe as people age.
Often, children may first experience food allergies and eczema, or itchy skin, before developing hay fever, Josephson said.
«This then worsens over the years, and patients then develop allergies to indoor allergens love dust and animals, or seasonal rhinitis, love ragweed, grass pollen, molds and tree pollen.»
Hay fever can also lead to other medical conditions. People who are allergic to weeds are more likely to get other allergies and develop asthma as they age, Josephson said. But those who get immunotherapy, such as allergy shots that assist people’s bodies get used to allergens, are less likely to develop asthma, he said.
