Dealing With a Hay Fever Cough

What Is Hay Fever?

Endless sneezing, coughing, itchy eyes, and runny nose — the symptoms of hay fever — may plague you during blooming seasons. Hay fever (also known as seasonal allergies) occurs when your body views certain particles as foreign invaders. Known as allergens, these particles can be anything from pollen to mold spores.

When your body is exposed to allergens, it releases histamines. Histamines are meant to protect you from harm, but they can also cause the allergy symptoms that make some seasons very uncomfortable. This includes a frequent cough that has others trying to get away from you for fear of getting sick.

While hay fever — and hay fever cough — aren’t contagious, they’re uncomfortable and can make you miserable. Keep reading to find out how to treat your cough at home, and even prevent it from happening again.

What Are the Symptoms of Hay Fever?


Growing seasons cause plants to bloom and molds to multiply, so you’ll usually experience your symptoms at the same time every year. This can help you confirm that your symptoms are due to hay fever and not a viral infection.

Symptoms associated with hay fever include:

  • coughing
  • sneezing
  • itchy nose
  • poor sense of smell or taste
  • runny or stuffy nose
  • sinus pain or pressure
  • watery or itchy eyes

It’s possible to experience hay fever symptoms year-round, particularly if you’re allergic to something indoors like dust mites, cockroaches, mold, or pet dander.

The good news about hay fever symptoms is that they tend to go away as you age. Children and young adults typically develop allergy symptoms, and they often start to subside as the body gets more used to the allergen.

What Causes a Hay Fever Cough?


A hay fever cough and other allergy symptoms will occur fairly quickly after you’ve been exposed to an allergen that bothers your body. When the allergen is taken away, your symptoms and cough usually go away too.

Seasonal hay fever triggers include:

  • grass pollen
  • ragweed pollen
  • spores that grow from fungi and molds
  • tree pollen

Year-round triggers for hay fever include:

  • cockroaches
  • dust mites
  • pet dander, such as from cats, dogs, or birds
  • spores from fungi and molds that grow indoors

These allergens set off a chain reaction after they get into your system. When you have a hay fever cough, you are experiencing the aftereffects of postnasal drip.

Postnasal drip occurs when the allergens irritate the lining of the nose. This triggers the nasal passages to produce mucus, a sticky substance that’s supposed to remove harmful or dirty particles from the air. Mucus associated with allergens tends to be thicker and more watery than the mucus your body produces when you aren’t sick or experiencing allergies. This watery mucus drips out of your nose and down your throat. This “tickles” the throat and leads to a hay fever cough.

This cough usually comes with a constant tickling feeling in the throat. If you’re exposed to your allergen when you’re outdoors, your coughing will most likely be more frequent in the daytime. However, your cough will generally be worse at night. This effect is largely due to gravity. During the day, you are standing and sitting up more than at night. As a result, mucus can drain more easily than at night when you are lying down.

Asthma is another common cause of a cough. When a person with asthma is exposed to an allergen, the airways can tighten, which causes a wheezing cough. Asthma symptoms include shortness of breath, chest tightness, and coughing.

Diagnosing a Hay Fever Cough


When you have an infection, the mucus in your body starts to thicken due to the presence of a virus or bacteria. The type of mucus your body is producing can help your doctor tell the difference between a hay fever cough and an infection. If you have thin mucus, as opposed to thick mucus that is difficult to cough up, allergies are usually to blame.

Your doctor will likely ask you about your symptoms, what makes them worse or better, and when you started noticing them.

Treatments for a Hay Fever Cough


A hay fever cough usually isn’t contagious, but it can be uncomfortable and irritate your throat. This causes it to feel scratchy and itchy. There are several ways to deal with a hay fever cough to help you start feeling better.


Medicines that dry up the postnasal drip can help. These are known as decongestants and many are available over the counter. Common decongestant ingredients are pseudoephedrine or phenylephrine. Another option is to take an antihistamine. This helps to block the release of histamines that cause the inflammation in the body. Over-the-counter options often have ingredients like chlorpheniramine or diphenhydramine.

Alternative Treatments

If you don’t want to take medicine (or it hasn’t worked for you), home remedies exist too. This includes inhaling steam, such as from a hot shower. The warmth helps to open up your nasal passages while the moist steam keeps them from drying out. Saline nose sprays can help to “wash out” the allergens and extra mucus, reducing the cough symptoms. These are available at a drugstore. You can also make your own by following these steps:

  • Add a cup of water to a clean bowl or basin.
  • Add 1/8 teaspoon of table salt.
  • Soak a clean washcloth in the basin.
  • Without wringing out the washcloth, lift it up to your nostril and inhale to take in the saline solution. You can repeat this about three times per day.

If none of these measures work, talk to your doctor about seeing an allergy specialist. An allergist can identify exactly what’s making you sneeze and cough and recommend targeted treatments. Allergy shots are one example, which involve exposing a person to small parts of a particular allergen to desensitize the body’s reaction.



Postnasal drip usually causes a hay fever cough. This condition can be treated with either medications or home remedies. If you know what allergens make you cough, avoid them whenever possible. This includes staying indoors on days when pollen counts are high. Changing your clothes and washing your hair and body after being outdoors can also help to reduce hay fever-causing allergens. If at-home remedies aren’t effective, talk to your doctor about other treatment options.
