What causes spring and fall allergies

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.


Pollen count

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. states.


Common allergens

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.

What causes spring and drop allergies

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.


Keep track of pollen counts.

If you know exactly which allergens you react to (a visit to your allergist can narrow it down), you can hold track of when that pollen is at its highest levels, and plan your outdoor activities accordingly.

Download a free app such as Pollen.com’s Allergy Alert, which will give the forecast for specific pollens in your city.

According to the Asthma and Allergy Foundation of America, pollen counts are highest correct after dawn in rural areas; in urban environments, prime sniffle time is between 10 a.m. and 3 p.m. Since rain and freezing weather slow below the release of pollen, your best bet for an outdoor adventure is generally just after a rainfall.


Hay fever treatments

Dr. Sarita Patil, an allergist with Massachusetts General Hospital’s Allergy Associates in Boston, talked to Live Science about strategies for outdoor lovers with seasonal allergies.

Patil suggested figuring out exactly what type of pollen you’re allergic to, and then avoiding planning outdoor activities during peak pollinating times in the months when those plants are in bloom.

Numerous grasses, for example, typically pollinate in tardy spring and early summer and release most of their spores in the afternoon and early evening.

Her other strategies: Be capable to identify the pollen perpetrator by sight; monitor pollen counts before scheduling outdoor time; go exterior at a time of day when the plants that make you go achoo are not pollinating; and wear protective gear love sunglasses, among other tips.

Allergy sufferers may also select to combat symptoms with medication designed to shut below or trick the immune sensitivity in the body. Whether over-the-counter or prescription, most allergy pills work by releasing chemicals into the body that bind naturally to histamine — the protein that reacts to the allergen and causes an immune response — negating the protein’s effect.

Other allergy remedies attack the symptoms at the source. Nasal sprays contain athletic ingredients that decongest by soothing irritated blood vessels in the nose, while eye drops both moisturize and reduce inflammation.

Doctors may also prescribe allergy shots, Josephson said.

For kids, allergy medications are tricky. A 2017 nationally representative poll of parents with kids between ages 6 and 12 found that 21% of parents said they had trouble figuring out the correct dose of allergy meds for their child; 15% of parents gave a kid an adult form of the allergy medicine, and 33% of these parents also gave their kid the adult dose of that medicine.

Doctors may also recommend allergy shots, a neti pot that can rinse the sinuses, or a Grossan Hydropulse — an irrigating system that cleans the nose of pollens, infection and environmental irritants, Josephson said.

Alternative and holistic options, along with acupuncture, may also assist people with hay fever, Josephson said.

People can also avoid pollen by keeping their windows closed in the spring, and by using air purifiers and air conditioners at home.

Probiotics may also be helpful in stopping those itchy eyes and runny noses.

What causes spring and drop allergies

A 2015 review published in the journal International Forum of Allergy and Rhinology found that people who suffer from hay fever may benefit from using probiotics, or «good bacteria,» thought to promote a healthy gut. Although the jury is still out on whether probiotics are an effective treatment for seasonal allergies, the researchers noted that these gut bacteria could hold the body’s immune system from flaring up in response to allergens — something that could reduce allergy symptoms.

Pulling on your coziest sweater and strolling through the park sounds love the perfectly way to spend a brisk autumn day — but when that scenario also involves a runny nose, itchy eyes, and a nagging cough, it’s not fairly as enjoyment. Though numerous people ponder of spring, with its blossoming trees and flowers, as the worst season for allergies, they can get just as bad or even worse for some people when the weather cools, says Edith Schussler, M.D., a pediatric allergist at Weill Cornell Medicine in New York.

The biggest culprit for drop allergies is ragweed — up to 20% of Americans are allergic to the weed that blooms every over the United States. And it’s a powerful allergen: In fact, just one ragweed plant can produce up to 1 billion grains of pollen during its single-season lifespan. In the past, the high season for ragweed allergies lasted from tardy August through September, but Dr. Schussler points out that that due to changes in weather patterns, the season has gotten longer and more brutal for allergy sufferers.

«We are having these longer, warmer falls, so the pollen sticks around much later in the season, from early August through October,» she explains. «With every that pollen going out, more ragweed is being seeded and growing, so it’s a vicious cycle.» You don’t just discover ragweed in bucolic country settings, either: «There is a lot of ragweed in cities as well, because the carbon dioxide from cars helps it grow,» says Dr.

Schussler.

In addition to ragweed, drop is prime season for indoor and outdoor molds. The fungus can collect up in piles of moist leaves — the extremely ones that kids love to jump in and adults need to rake up every weekend.

But you can still enjoy the most beautiful season of the year without wrapping yourself up in a Hazmat suit or hiding in your basement until the first snowfall. Here’s how:


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.
