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]
How long does it last?
Asthma is a long-term condition for numerous people, particularly if it first develops when you’re an adult.
In children, it sometimes disappears or improves during the teenage years, but can come back later in life.
The symptoms can generally be controlled with treatment.
Most people will own normal, athletic lives, although some with more severe asthma may have ongoing problems.
Symptoms of asthma
The main symptoms of asthma are:
- a tight chest, which may feel love a band is tightening around it
- a whistling sound when breathing (wheezing)
The symptoms can sometimes get temporarily worse. This is known as an asthma attack.
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.
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.
