Understanding causes and symptoms of seasonal allergies

What triggers seasonal allergies in Fresno and Merced?

Seasonal allergies happen when your immune system reacts to airborne allergens like pollen, mold spores, and grasses. In Fresno and Merced, where agriculture and changing seasons play a big role, these allergens are especially active in spring, summer, and fall. Your body mistakenly identifies these particles as threats, releasing histamines that cause those all-too-familiar allergy symptoms.

The main seasonal allergy triggers

Pollen

Released by trees (spring), grasses (late spring to summer), and weeds (late summer to fall).

Mold Spores

Thrive in damp environments, released in spring and fall from outdoor sources like fallen leaves and indoor areas like basements.

Dust and Pollution

Dust mixes with outdoor pollutants, worsening symptoms, especially with air pollution.

Climate and Weather Changes

Warm, dry days promote pollen release, while rain and wind can spread mold spores and pollen.

Recognizing the symptoms of seasonal allergies

Identifying the symptoms of seasonal allergies early is key to managing them. These symptoms can vary in severity and may range from mild irritations to more intense reactions that affect your daily activities. Common symptoms include:

Sneezing

Often occurs in fits, especially after exposure to pollen or mold.

Runny or Congested Nose

Allergens can block nasal passages or cause a constant runny nose.

Itchy or Watery Eyes

Red, itchy eyes are common, often accompanied by allergic conjunctivitis.

Post-nasal Drip

Mucus drains down the throat, causing coughing or a scratchy sensation.

Sinus Pressure or Headaches

Inflammation can cause pain around the eyes, forehead, and cheeks.

Fatigue

The body’s immune response can leave you feeling tired and unfocused.

Coughing or Throat Irritation

Triggered by post-nasal drip or direct allergic response.

Wheezing or Shortness of Breath

Especially common in those with asthma, triggered by seasonal allergens.

Customizing your allergy management plan

Seasonal allergy symptoms are influenced by the specific allergens present during different times of the year. Here’s a breakdown of symptoms by season:

Spring Allergies

Tree pollen is most prevalent, and symptoms may include itchy eyes, sneezing, and nasal congestion.

Summer Allergies

Grass pollen dominates, leading to more sneezing and a runny nose, with outdoor activities worsening symptoms.

Fall Allergies

Weed pollen, such as ragweed, causes severe symptoms like sneezing, nasal congestion, and itchy eyes.

Mold Allergies

Most problematic in both spring and fall when mold spores are most active.

Frequently Asked Questions

What are the most common causes of seasonal allergies?

The primary causes of seasonal allergies include pollen from trees, grasses, and weeds, as well as mold spores. These allergens are most prevalent during specific seasons, such as spring, summer, and fall. Pollen and mold spores are carried by the wind and can trigger allergic reactions when they come into contact with the body.

How can I tell if I have seasonal allergies or a common cold?

Seasonal allergies are often confused with the common cold, but there are key differences. Allergies typically cause sneezing, a runny or stuffy nose, itchy or watery eyes, and a scratchy throat without fever. Cold symptoms, on the other hand, may include fatigue, body aches, and a sore throat with a possible fever. If your symptoms last more than a week or occur at certain times of the year, they’re more likely due to allergies.

Can seasonal allergies be prevented?

While it may not be possible to completely prevent seasonal allergies, you can take steps to minimize your exposure to allergens. These include staying indoors during peak pollen times, using air purifiers, wearing sunglasses to protect your eyes, and keeping windows closed during allergy season. Additionally, regular cleaning to reduce dust and mold in your home can help alleviate symptoms.

How are seasonal allergies treated?

Treatment for seasonal allergies may include over-the-counter antihistamines, nasal sprays, and eye drops. In some cases, a doctor may prescribe allergy medications or recommend allergy shots (immunotherapy) to help reduce sensitivity to allergens. At Sierra Allergy, Asthma, and Sinus Center, we provide personalized treatment plans that may include a combination of medications, lifestyle changes, and other interventions.

When should I see an allergy specialist for seasonal allergies?

If your symptoms are frequent, severe, or persistent despite using over-the-counter medications, it’s time to see an allergy specialist. A healthcare provider can perform tests to determine the specific triggers causing your symptoms and recommend a more effective treatment plan. If allergies are affecting your quality of life, such as interfering with your sleep or work, it’s important to get professional help.
