Seasonal Allergies

• Most commonly triggered by tree, grass, or weed pollen
• Symptoms often occur in spring, summer, or fall
• Seasonal allergies are not contagious
• Symptoms can range from mild to severe
• Effective treatments and preventive strategies are available

Common symptoms of seasonal allergies include:

• Sneezing
• Runny or stuffy nose
• Itchy nose, eyes, or throat
• Watery or red eyes
• Postnasal drip
• Cough
• Fatigue due to poor sleep
• Skin rashes and hives

Seasonal allergies occur when the immune system identifies harmless airborne substances as threats and releases chemicals such as histamine.

Common triggers include:

• Tree pollen in spring
• Grass pollen in late spring and summer
• Weed pollen in late summer and fall
• Outdoor mold spores

You may be at higher risk for seasonal allergies if you:

• Have a family history of allergies or asthma
• Have asthma or eczema
• Live in areas with high pollen counts
• Spend significant time outdoors during allergy seasons

Treatment focuses on symptom relief and allergen avoidance and may include:

• Antihistamines
• Nasal corticosteroid sprays
• Decongestants
• Allergy eye drops
• Immunotherapy (allergy shots or tablets) for long-term control
• Lifestyle strategies to limit pollen exposure

See a doctor if allergy symptoms are severe, persistent, interfere with sleep or daily activities, or do not improve with over-the-counter treatments.
