If seasonal sneezing, itchy eyes, or a constantly runny nose makes certain times of the year difficult, you may be dealing with hay fever. These symptoms can be frustrating, especially when they interfere with sleep, work, or daily activities.
Hay fever is an allergic reaction to airborne substances such as pollen, grass, or mold spores. It can cause congestion, sneezing, itchy or watery eyes, and a runny nose. When symptoms become severe or difficult to manage, our Sugar Land Hospital is available for prompt medical evaluation.
What Causes Hay Fever?
Hay fever develops when your immune system reacts too strongly to substances that are usually harmless. This reaction can make everyday exposure to airborne allergens uncomfortable, causing symptoms such as sneezing, nasal congestion, a runny nose, and itchy or watery eyes. Symptoms may appear seasonally or continue throughout the year, depending on what triggers your allergies. Identifying your specific triggers can help reduce exposure and improve symptom control.
Tree Pollen
Tree pollen is a common seasonal trigger of hay fever, particularly during early spring. Trees release tiny pollen particles into the air for reproduction, and these particles can enter the nose and eyes. In sensitive people, the immune system treats the pollen as a threat and releases chemicals such as histamine. This can lead to sneezing, congestion, nasal drainage, and itchy eyes.
Grass Pollen
Grass pollen commonly causes hay fever symptoms during late spring and summer. Pollen becomes airborne and can be inhaled or contact the eyes and nasal passages. People who are sensitive may develop repeated sneezing, a runny or blocked nose, and itchy eyes after exposure. Outdoor activities can increase contact with grass pollen.
Weed Pollen
Weed pollen can trigger hay fever, especially during late summer and fall. Ragweed is one of the most common weed-related allergens and can release large amounts of pollen into the air. Even small amounts may cause symptoms in people who are sensitive. Sneezing, nasal congestion, itchy eyes, and throat irritation are common reactions.
Mold Spores
Mold can release microscopic spores that become airborne and trigger allergic symptoms. Outdoor mold may be more noticeable in damp soil, piles of leaves, and other moist areas, while indoor mold can grow in bathrooms, basements, or areas with water damage. Breathing in mold spores may cause sneezing, congestion, a runny nose, and itchy eyes.
Dust Mites
Dust mites are microscopic organisms commonly found in household dust, mattresses, bedding, carpets, and upholstered furniture. Their waste particles can become airborne and trigger allergic reactions when inhaled. Unlike pollen, dust mite exposure can occur throughout the year. Symptoms may include persistent congestion, sneezing, runny nose, and itchy or watery eyes.
Pet Dander
Pet dander consists of tiny flakes of skin shed by animals and can trigger allergy symptoms in sensitive people. Proteins found in an animal’s skin flakes, saliva, and urine can also contribute to allergic reactions. These allergens can remain on clothing, furniture, carpets, and other surfaces. Exposure may cause sneezing, congestion, itchy eyes, or a runny nose.
Cockroach Allergens
Cockroach particles, including debris and droppings, can become airborne and trigger allergic reactions. Exposure is more common in homes or buildings where cockroaches are present. These allergens may contribute to persistent nasal symptoms, particularly when exposure occurs regularly. Keeping living areas clean and addressing infestations can help reduce exposure.
Airborne Allergens
Hay fever can also be triggered by other airborne substances that enter the nose or contact the eyes. Environmental allergens can cause the immune system to release histamine and other inflammatory chemicals in sensitive individuals. Symptoms may develop soon after exposure and can worsen with continued contact. Avoiding known allergens is an important part of managing symptoms.
Hay Fever Symptoms That Need Medical Attention
Hay fever is usually not dangerous, but severe or persistent symptoms may require medical care. Seek prompt evaluation if symptoms worsen, affect breathing, or significantly interfere with daily life.
- Difficulty breathing or severe shortness of breath.
- Wheezing or chest tightness.
- Swelling of the lips, tongue, face, or throat.
- Symptoms that persist or continue to worsen.
- Severe sinus pain or facial swelling.
- High fever, which may indicate another illness.
- Severe headache or vision changes.
- Symptoms that seriously disrupt sleep or daily activities.
If you experience severe or concerning symptoms, search for the nearest emergency room for prompt medical evaluation and emergency care.
Hay Fever Treatment
Hay fever treatment can help relieve uncomfortable symptoms and make daily activities easier. The best approach depends on your symptoms, their severity, and the allergens triggering them. A healthcare professional can recommend an appropriate plan, especially when symptoms are persistent or difficult to control.
Antihistamines
Antihistamines help block histamine, a chemical released during an allergic reaction. They can reduce symptoms such as sneezing, itching, a runny nose, and watery eyes. Some options are available over the counter, while others may require a prescription. Certain antihistamines can cause drowsiness, so follow medical advice and medication instructions carefully.
Nasal Corticosteroid Sprays
Nasal corticosteroid sprays can help reduce inflammation inside the nose and improve congestion, sneezing, and a runny or itchy nose. They are commonly recommended for people with persistent or bothersome hay fever symptoms. These sprays may take time to provide their full benefit and should be used as directed.
Saline Nasal Rinses
Saline nasal sprays or rinses can help remove mucus and allergens from the nasal passages. They may provide relief from congestion and dryness and can be used alongside other treatments. When performing nasal irrigation, use appropriately prepared distilled, sterile, or previously boiled and cooled water.
Allergy Immunotherapy
Allergy immunotherapy may be considered when symptoms remain difficult to control despite other treatments. This approach gradually exposes the body to specific allergens through allergy shots or, for certain allergies, tablets placed under the tongue. Treatment is supervised by a qualified healthcare professional and may provide longer-term symptom relief.

Frequently Asked Questions
Is Hay Fever Contagious?
No, hay fever is not contagious. It is an allergic reaction caused by exposure to triggers such as pollen, mold, dust mites, or pet dander and cannot spread from person to person.
How Long Does Hay Fever Last?
Hay fever can last for days, weeks, or throughout an allergy season, depending on the trigger and continued exposure. Symptoms may persist year-round for people with indoor allergies such as dust mites or pet dander.
