Allergy season is a challenging time for many individuals, and Florida is no exception. With its warm weather and diverse flora, the state experiences a range of allergens that can cause symptoms ranging from mild to severe, from causes such as the pollen of grasses, weeds, and trees, or from mold or dust mites. Whether you are a resident of Florida or planning a visit, this article will provide valuable information to help you navigate the state’s allergy season, and to help your pet do the same.

An Overview of Allergies

Allergies are the body’s reaction to substances known as allergens. These can include the venom of bee stings, certain kinds of foods, dust mites, pet dander, mold spores, and pollen. The immune system of an allergic person releases chemicals like histamine, which is how it fights off allergens. This can cause symptoms like sneezing, itching, rashes, hives, and in severe cases, difficulty breathing. You can lessen allergic reactions by reducing your exposure to allergens. Medication like decongestants and antihistamines can be used to mitigate the symptoms.

When is Allergy Season in Florida?

Allergy season in Florida varies depending on the type of allergen. Here are some of the most common allergens in the state and when they peak:

  1. Mold: Florida’s high humidity and warm weather create ideal conditions for mold growth, so mold allergies can occur year-round, but tend to be worse in the summer and fall.
  2. Oak: Oak trees produce large amounts of pollen, which can cause symptoms such as sneezing, runny nose, and itchy eyes. Oak pollen season typically begins in late March and lasts through May.
  3. Cedar: Cedar trees also produce a lot of pollen, which can cause similar symptoms as oak. Cedar pollen season typically begins in January and lasts through April.
  4. Juniper: Juniper trees produce a lot of pollen, which can cause similar symptoms as oak and cedar. Juniper pollen season typically begins in late December and lasts through April.
  5. Ragweed: Ragweed is a common allergen that can cause symptoms such as sneezing, runny nose, and itchy eyes. Ragweed pollen season typically peaks in September and October.
  6. Palmetto: Saw palmetto and Sabal palm are Florida native plants that can cause allergies as well. Their pollen season typically peaks in the summer.
  7. Grass: Different types of grasses can cause allergy symptoms and can start releasing pollen as early as February, but the peak of grass pollen season is usually in May and June in Florida.

Florida’s subtropical climate produces lush vegetation, so many other plants and trees can also cause allergies there. Additionally, pollen counts, and the duration of pollen season can vary depending on the weather and other environmental factors. Also, note that everyone’s sensitivity to allergens can vary, so some people may experience symptoms earlier or later in the season than others.

Monitoring Pollen Count

In the United States, trees tend to pollinate in spring, usually from March to May. In warm climates like Florida, they can start pollinating as early as January and have more than one peak during the year. Other kinds of plants, such as wildflowers, weeds, and grasses all have their own allergy seasons. Scientists use various methods to sample the air to determine the pollen count; that is, the number of pollen grains per cubic meter of air. Local news and websites report the pollen count and forecast at the height of allergy season. Pollen count can vary based on weather, location, wind direction and speed, temperature, and humidity.

What is Involved in Allergy Testing?

The only way to be certain about what you are allergic to is to be tested by an allergist. This is usually done through a skin test or a blood test. In a skin test, a small amount of various allergens is placed on the skin. If it causes a red welt, this is an indication that you are allergic to that substance. A blood test can tell whether you have developed antibodies to allergens but it is not considered as accurate and precise as a skin test. A negative test result does not necessarily rule out an allergy. Sometimes more than one test is necessary to reach a determination. An allergist will interpret the results of the tests and provide a diagnosis, recommendations for treatment, and advice on how to manage your symptoms.

What is Non-Allergenic Rhinitis?

Sometimes an allergy test returns negative results, yet you clearly still have allergy symptoms. This may be a case of non-allergenic rhinitis. Non-allergenic rhinitis can result from a viral infection, smoke, dust, or chemical exposure, hormonal issues, or as a side effect of some medications. It can also be the result of structural problems in the nasal passages that contribute to chronic inflammation. Although the causes of non-allergenic rhinitis are not always known, it often responds to allergy medications as well as avoiding likely triggers. In the case of structural issues in the nose or sinuses, your doctor might recommend surgical options.

Preventing and Reducing Allergies

Here are few suggestions of ways you might prevent or reduce the worst of your allergies:

  • Shut doors and windows and use air conditioning
  • Avoid outdoor activities at the worst of allergy season
  • Shower and put on clean clothes after going outside on high pollen days
  • Wash bedding regularly in hot water if dust mites aggravate your allergies
  • Vacuum and dust frequently
  • If pet dander bothers you, keep your pets in certain areas of your house and task other family members with caring for them
  • Keep track of the time of year when your allergies are worse and begin taking over-the-counter medications preventatively
  • Consider changing your landscaping if you have plantings that increase your allergies

What Are the Symptoms of Allergies in Pets?

Just like humans, pets can develop different types of allergies. Some of the most common types of allergies in pets include food allergies, environmental allergies, and flea allergy dermatitis. Symptoms of allergies in pets can vary depending on the type of allergy and the pet, but common signs include itching, scratching, biting or licking of the skin, hair loss, red or irritated skin, and respiratory issues. A veterinarian will be able to diagnose and treat the allergy and provide appropriate recommendations. In some cases, pets may require a combination of treatments such as allergen-specific immunotherapy, medications, and changes to their diet or environment.

Are Human Allergy Medicines Safe for Pets?

Pets can take some human allergy medicines but not all. Some medicines may be suitable for dogs but toxic to cats. The dosage must also be regulated based on the weight of the pet. Possible interactions with other medications should also be considered. It’s important to confer with your veterinarian to make sure you are treating your pet safely and effectively.
