What are 2 common symptoms associated with seasonal allergies

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.


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.


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. 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.


Symptoms

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. [Oral Allergy Syndrome: 6 Ways to Avoid an Itchy, Tingling Mouth]

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.

What are 2 common symptoms associated with seasonal allergies

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.


Severe allergic reaction (anaphylaxis)

In rare cases, an allergy can lead to a severe allergic reaction, called anaphylaxis or anaphylactic shock, which can be life threatening.

This affects the whole body and usually develops within minutes of exposure to something you’re allergic to.

Signs of anaphylaxis include any of the symptoms above, as well as:

Anaphylaxis is a medical emergency that requires immediate treatment.

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.

What are 2 common symptoms associated with seasonal allergies

«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).

What are 2 common symptoms associated with seasonal allergies

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]


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.

What are 2 common symptoms associated with seasonal allergies

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. 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.

Treatment

There are numerous ways to treat seasonal allergies, depending on how severe the symptoms are. The most significant part of treatment is knowing what allergens are at work. Some kids can get relief by reducing or eliminating exposure to allergens that annoy them.

If certain seasons cause symptoms, hold the windows closed, use air conditioning if possible, and stay indoors when pollen/mold/weed counts are high.It’s also a excellent thought for kids with seasonal allergies to wash their hands or shower and change clothing after playing outside.

If reducing exposure isn’t possible or is ineffective, medicines can assist ease allergy symptoms.

These may include decongestants, antihistamines, and nasal spray steroids. If symptoms can’t be managed with medicines, the doctor may recommend taking your kid to an allergist or immunologist for evaluation for allergy shots (immunotherapy), which can assist desensitize kids to specific allergens.

If you feel love you’re always getting ill, with a cough or head congestion, it’s time to see an allergist.

What are 2 common symptoms associated with seasonal allergies

You may ponder you’re certain pollen is causing your suffering, but other substances may be involved as well. More than two-thirds of spring allergy sufferers actually own year-round symptoms. Your best resource for finding what’s causing your suffering and stopping it, not just treating the symptoms, is an allergist.

Work together with your allergist to devise strategies to avoid your triggers:

  1. To avoid pollen, know which pollens you are sensitive to and then check pollen counts.

    In spring and summer, during tree and grass pollen season, levels are highest in the evening. In tardy summer and early drop, during ragweed pollen season, levels are highest in the morning.

  2. Take a shower, wash your hair and change your clothes after you’ve been working or playing outdoors.
  3. Keep windows and doors shut at home and in your car during allergy season.
  4. Monitor pollen and mold counts. Weather reports in newspapers and on radio and television often include this information during allergy seasons.
  5. Wear a NIOSH-rated 95 filter mask when mowing the lawn or doing other chores outdoors, and take appropriate medication beforehand.

Your allergist may also recommend one or more medications to control symptoms.

Some of the most widely recommended drugs are available without a prescription (over the counter); others, including some nose drops, require a prescription.

If you own a history of prior seasonal problems, allergists recommend starting medications to alleviate symptoms two weeks before they are expected to begin.

One of the most effective ways to treat seasonal allergies linked to pollen is immunotherapy (allergy shots). These injections expose you over time to gradual increments of your allergen, so you study to tolerate it rather than reacting with sneezing, a stuffy nose or itchy, watery eyes.

Signs and Symptoms

If your kid develops a «cold» at the same time every year, seasonal allergies might be to blame.

Allergy symptoms, which generally come on suddenly and final as endless as a person is exposed to the allergen, can include:

  1. coughing
  2. clear, runny nose
  3. nasal congestion
  4. itchy nose and/or throat
  5. A drop of a purified liquid form of the allergen is dropped onto the skin and the area is pricked with a little pricking device.If a kid reacts to the allergen, the skin will swell a little in that area.
  6. sneezing
  7. A little quantity of allergen is injected just under the skin. This test stings a little but isn’t extremely painful. After about 15 minutes, if a lump surrounded by a reddish area appears (like a mosquito bite) at the injection site, the test is positive.

These symptoms often come with itchy, watery, and/or red eyes, which is called allergic conjunctivitis.

Kids who own wheezing and shortness of breath in addition to these symptoms might own allergies that triggerasthma.

About Seasonal Allergies

«Achoo!» It’s your son’s third sneezing fit of the morning, and as you hand him another tissue you wonder if these cold-like symptoms — the sneezing, congestion, and runny nose — own something to do with the recent weather change. If he gets similar symptoms at the same time every year, you’re likely right: seasonal allergies are at work.

Seasonal allergies, sometimes called «hay fever» or seasonal allergic rhinitis, are allergy symptoms that happen during certain times of the year, generally when outdoor molds release their spores, and trees, grasses, and weeds release tiny pollen particles into the air to fertilize other plants.

The immune systems of people who are allergic to mold spores or pollen treat these particles (called allergens) as invaders and release chemicals, including histamine, into the bloodstream to defend against them.

It’s the release of these chemicals that causes allergy symptoms.

People can be allergic to one or more types of pollen or mold. The type someone is allergic to determines when symptoms happen. For example, in the mid-Atlantic states, tree pollination is February through May, grass pollen runs from May through June, and weed pollen is from August through October — so kids with these allergies are likely to own increased symptoms at those times. Mold spores tend to peak midsummer through the drop, depending on location.

Even kids who own never had seasonal allergies in years past can develop them.

What are 2 common symptoms associated with seasonal allergies

Seasonal allergies can start at almost any age, though they generally develop by the time someone is 10 years ancient and reach their peak in the early twenties, with symptoms often disappearing later in adulthood.

Diagnosis

Seasonal allergies are fairly simple to identify because the pattern of symptoms returns from year to year following exposure to an allergen.

Talk with your doctor if you ponder your kid might own allergies. The doctor will enquire about symptoms and when they appear and, based on the answers and a physical exam, should be capable to make a diagnosis.

If not, the doctor may refer you to an allergist for blood tests or allergy skin tests.

To discover an allergy’s cause, allergists generally do skin tests in one of two ways:

  • Insect bites and stings (usually in spring and summer)
  • Candy ingredients (Halloween, Christmas, Valentine’s Day, Easter)
  • Chlorine in indoor and outdoor swimming pools
  • A little quantity of allergen is injected just under the skin. This test stings a little but isn’t extremely painful.

    After about 15 minutes, if a lump surrounded by a reddish area appears (like a mosquito bite) at the injection site, the test is positive.

  • Smoke (campfires in summer, fireplaces in winter)
  • A drop of a purified liquid form of the allergen is dropped onto the skin and the area is pricked with a little pricking device.If a kid reacts to the allergen, the skin will swell a little in that area.
  • Pine trees and wreaths (Thanksgiving to Christmas))

Even if a skin test or a blood test shows an allergy, a kid must also own symptoms to be definitively diagnosed with an allergy. For example, a kid who has a positive test for grass pollen and sneezes a lot while playing in the grass would be considered allergic to grass pollen.

Seasonally Related Triggers

While the term “seasonal allergies” generally refers to grass, pollen and mold, there is a diverse group of triggers that are closely tied to specific seasons.

Among them:

  1. Chlorine in indoor and outdoor swimming pools
  2. Candy ingredients (Halloween, Christmas, Valentine’s Day, Easter)
  3. Insect bites and stings (usually in spring and summer)
  4. Smoke (campfires in summer, fireplaces in winter)
  5. Pine trees and wreaths (Thanksgiving to Christmas))

Allergic rhinitis, also known as hay fever, is a type of inflammation in the nose which occurs when the immune system overreacts to allergens in the air.[6] Signs and symptoms include a runny or stuffy nose, sneezing, red, itchy, and watery eyes, and swelling around the eyes.[1] The fluid from the nose is generally clear.[2] Symptom onset is often within minutes following allergen exposure and can affect sleep, and the ability to work or study.[2][8] Some people may develop symptoms only during specific times of the year, often as a result of pollen exposure.[3] Numerous people with allergic rhinitis also own asthma, allergic conjunctivitis, or atopic dermatitis.[2]

Allergic rhinitis is typically triggered by environmental allergens such as pollen, pet hair, dust, or mold.[3] Inherited genetics and environmental exposures contribute to the development of allergies.[3] Growing up on a farm and having multiple siblings decreases this risk.[2] The underlying mechanism involves IgE antibodies that attach to an allergen, and subsequently result in the release of inflammatory chemicals such as histamine from mast cells.[2] Diagnosis is typically based on a combination of symptoms and a skin prick test or blood tests for allergen-specific IgE antibodies.[4] These tests, however, can be falsely positive.[4] The symptoms of allergies resemble those of the common cold; however, they often final for more than two weeks and typically do not include a fever.[3]

Exposure to animals early in life might reduce the risk of developing these specific allergies.[3] Several diverse types of medications reduce allergic symptoms: including nasal steroids, antihistamines, such as diphenhydramine, cromolyn sodium, and leukotriene receptor antagonists such as montelukast.[5] Often times, medications do not completely control symptoms and own side effects.[2] Exposing people to larger and larger amounts of allergen, known as allergen immunotherapy (AIT), is often effective.[6] The allergen can be as an injections under the skin or as a tablet under the tongue.[6] Treatment typically lasts three to five years after which benefits may be prolonged.[6]

Allergic rhinitis is the type of allergy that affects the greatest number of people.[9] In Western countries, between 10–30% of people are affected in a given year.[2][7] It is most common between the ages of twenty and forty.[2] The first precise description is from the 10th century physician Rhazes.[10] Pollen was identified as the cause in 1859 by Charles Blackley.[11] In 1906, the mechanism was sure by Clemens von Pirquet.[9] The link with hay came about due to an early (and incorrect) theory that the symptoms were brought about by the smell of new hay.[12][13]

Even if a skin test or a blood test shows an allergy, a kid must also own symptoms to be definitively diagnosed with an allergy.

For example, a kid who has a positive test for grass pollen and sneezes a lot while playing in the grass would be considered allergic to grass pollen.

Main allergy symptoms

Common symptoms of an allergic reaction include:

  1. swollen lips, tongue, eyes or face
  2. a raised, itchy, red rash (hives)
  3. wheezing, chest tightness, shortness of breath and a cough
  4. itchy, red, watering eyes (conjunctivitis)
  5. tummy pain, feeling ill, vomiting or diarrhoea
  6. sneezing and an itchy, runny or blocked nose (allergic rhinitis)
  7. dry, red and cracked skin

The symptoms vary depending on what you’re allergic to and how you come into contact with it.

For example, you may have a runny nose if exposed to pollen, develop a rash if you own a skin allergy, or feel sick if you eat something you’re allergic to.

See your GP if you or your kid might own had an allergic reaction to something. They can assist determine whether the symptoms are caused by an allergy or another condition.
