How to Manage Allergy Season in Los Angeles

Los Angeles may be known for its sunshine and mild climate, but for allergy sufferers, spring and fall can bring months of sneezing, congestion, and itchy eyes. Pollen, dust, and even LA’s air pollution can make allergy symptoms worse, leaving many people feeling miserable. If you’re struggling with seasonal allergies, understanding the triggers and finding the right treatment can help you breathe easier. Here’s everything you need to know about managing allergy season in Los Angeles.


What Causes Seasonal Allergies in Los Angeles?

Unlike some parts of the country where allergies are mainly a spring issue, Los Angeles experiences multiple allergy seasons due to its diverse plant life and year-round mild temperatures. The most common triggers include:

1. Tree Pollen (Winter to Late Spring)

Southern California trees like oak, sycamore, pine, and cedar release pollen between December and May, triggering allergic reactions in many residents.

2. Grass Pollen (Spring to Early Summer)

Bermudagrass, ryegrass, and bluegrass thrive in LA, especially in parks and residential areas. Their pollen is a major allergy trigger in April through July.

3. Weed Pollen (Late Summer to Fall)

Ragweed and sagebrush pollen levels rise between August and November, causing hay fever symptoms for many people in LA.

4. Mold and Dust (Year-Round Allergens)

Los Angeles’ dry conditions cause dust mites and mold spores to linger year-round. Rainy weather can temporarily increase mold growth, making symptoms worse.

5. Air Pollution and Smog

Unlike pollen allergies, LA’s notorious air pollution doesn’t cause allergies but can worsen symptoms by irritating the respiratory system. Combined with pollen exposure, it can make allergy season even more unbearable.


Symptoms of Seasonal Allergies

If you’re unsure whether you have allergies or a lingering cold, look for these common symptoms:

  • Sneezing and congestion – Often persistent, especially outdoors or in the morning.
  • Itchy, watery eyes – A classic sign of pollen exposure.
  • Runny or stuffy nose – Nasal inflammation caused by allergens.
  • Scratchy throat and postnasal drip – Caused by mucus buildup.
  • Coughing or wheezing – Especially for those with asthma or sensitivity to air pollution.
  • Fatigue – Allergies can make you feel sluggish and drained.

If symptoms last more than two weeks and worsen outdoors, allergies are likely the culprit.


How to Reduce Allergy Symptoms

While avoiding allergens entirely is impossible, you can take steps to minimize your exposure and reduce symptoms:

1. Check Daily Pollen Counts

Before heading outside, check local pollen forecasts on weather apps. On high-pollen days, try to stay indoors, especially in the morning when pollen levels peak.

2. Keep Windows Closed

Even though fresh air is nice, open windows let pollen inside. Use air conditioning and HEPA filters to keep indoor air clean.

3. Shower After Spending Time Outdoors

Pollen sticks to skin, hair, and clothing. Showering and changing clothes after outdoor activities can prevent bringing allergens into your home.

4. Wash Bedding and Clothes Frequently

Pollen and dust mites settle in fabrics, so wash your sheets, pillowcases, and clothes regularly in hot water to remove allergens.

5. Wear Sunglasses and a Hat

Protect your eyes from airborne pollen by wearing wraparound sunglasses. A hat can also help prevent pollen from collecting in your hair.

6. Use a Nasal Rinse

Saline sprays or neti pots can help flush out allergens from your nasal passages, reducing congestion and irritation.


Best Over-the-Counter Allergy Medications

If lifestyle changes aren’t enough, over-the-counter (OTC) medications can help manage symptoms. The right choice depends on the severity of your allergies:

1. Antihistamines (For Sneezing & Itchy Eyes)

Antihistamines block the histamine response that causes allergy symptoms. Options include:

  • Loratadine (Claritin) – Non-drowsy and long-lasting.
  • Cetirizine (Zyrtec) – Effective for 24-hour relief but can cause slight drowsiness.
  • Fexofenadine (Allegra) – Fast-acting and non-drowsy.

2. Decongestants (For Stuffy Nose & Sinus Pressure)

If congestion is your main issue, decongestants can provide quick relief:

  • Pseudoephedrine (Sudafed) – Effective but can raise blood pressure, so consult your doctor if you have hypertension.
  • Nasal Sprays (Afrin, Flonase, Nasacort) – Work directly on nasal inflammation but should not be used for more than three days in a row to prevent rebound congestion.

3. Allergy Eye Drops (For Itchy, Watery Eyes)

  • Ketotifen (Zaditor, Alaway) – Antihistamine eye drops for fast relief.
  • Artificial tears – Help flush allergens out of the eyes.

Probiotics and Allergy Relief: Can They Help?

Emerging research suggests that gut health plays a role in immune system balance, and probiotics may help reduce allergy symptoms over time. Some studies show that probiotic supplements, especially those containing Lactobacillus and Bifidobacterium strains, can help regulate immune responses and lower inflammation.

If you’re looking for a simple way to incorporate probiotics into your routine, probiotic gummies are an easy, tasty option. They provide beneficial bacteria that may help your immune system respond better to allergens, potentially reducing the severity of symptoms. While they won’t replace antihistamines, they can be a helpful addition to your allergy-fighting strategy.


When to See a Doctor About Allergies

For many people, OTC medications and lifestyle changes provide enough relief, but if your allergies are interfering with daily life, it may be time to see a doctor. Consider seeking medical help if:

  • Allergy medications aren’t effective or cause side effects.
  • You experience frequent sinus infections or severe congestion.
  • Your allergies trigger asthma symptoms like wheezing or shortness of breath.
  • You’re interested in long-term relief options like allergy shots (immunotherapy).
