Common Fall Allergies and Simple Ways to Avoid Them
The immune system, at times, interprets certain foreign substances that come into contact with the body as threats. In such cases, it triggers a reaction by releasing chemicals such as histamines, leukotrienes, and prostaglandins to fight the foreign substance and protect the body. This reaction may manifest as a runny nose, itchy or watery eyes, coughing and, at times, more serious symptoms like difficulty breathing. These reactions are commonly called allergies, and the substances that cause allergies are called allergens.
As fall approaches, allergens such as mould, ragweed pollen and dust mites become more common and may cause serious allergic reactions in individuals who are susceptible. This article explores common allergies this fall and discusses practical ways to manage them.
What are Fall Allergies?
Fall allergies are a kind of seasonal allergy that is mostly triggered by allergens that become increasingly common with the changing of the seasons. Exposure to these substances can result in symptoms such as itchy eyes, sneezing, congestion in the nose, and even respiratory problems.
What are Fall Seasonal Allergy Symptoms?
The symptoms associated with seasonal allergies fall are consistent with those of allergic rhinitis and may include:
● Nasal Congestion
● Itchy Eyes
● Runny Nose
● Sneezing
● Postnasal Drip
What Are the Causes of Fall Allergies?
Understanding common triggers and taking the necessary precautions is crucial for reducing seasonal allergies in the fall.
1. Ragweed Pollen
A major fall allergen, ragweed releases large amounts of pollen from late summer through autumn. When inhaled, the immune system overreacts, identifying the pollen as a threat and releasing chemicals like histamine, which cause allergy symptoms.
Prevention Strategies:
● Stay indoors during peak pollen hours
● Keep the windows of the house and car closed to keep the pollen out.
● To reduce pollen tracking, take off shoes and outerwear before entering the house.
● Regularly vacuum and wash linens, curtains, and clothing.
Weeds such as cocklebur, lamb’s quarter (pigweed), mugwort, nettle, Russian thistle, sagebrush, and tumbleweed also release pollen that can trigger fall allergies.
2. Mould and Mildew
Mould and mildew thrive in both indoor and outdoor environments, growing on damp fallen leaves and in moist areas such as basements and bathrooms. They emit particles into the atmosphere, which, when inhaled, can cause an allergic reaction. The immune system views these spores as harmful, resulting in inflammation.
Prevention Strategies:
● Clear fallen leaves from yards, and avoid creating piles that can harbour mould spores.
● When raking or cleaning, wear protective masks and keep compost piles away from houses.
● Use vinegar or store-bought mildew removers to clean mould-prone areas on a regular basis.
3. Dust Mites
Dust mites are minute organisms that are frequently found in homes and feed on the flakes of human skin. They produce waste particles and body fragments that become airborne and are easily inhaled. The immune system identifies these particles as harmful, causing an allergic reaction. They are difficult to eradicate entirely and like warm, humid conditions.
Prevention Strategies:
● Clean air vents before using heating systems for the first time after summer.
● Utilise dust-proof covers for mattresses and pillows.
● Maintain indoor humidity below 70%.
● Consider replacing wall-to-wall carpeting with hardwood floors to reduce dust mite populations.
4. Pet Dander
Pet dander, consisting of tiny skin cells, can become airborne. When inhaled, these particles can trigger the immune system, causing allergy symptoms like sneezing, coughing, and itchy eyes.
Prevention Strategies:
● Individuals with known allergies should limit their interaction with pets.
● To reduce fall allergies, regularly bathe and brush the pets.
● Pets should be kept off furniture and away from air vents.
● Use air purifiers to reduce pet allergens in the home.
How Are Fall Allergies Diagnosed?
Fall allergies can be diagnosed by a healthcare professional using the following tests:
- Skin Tests: In this method, the doctor makes small pricks on the skin’s surface and applies a tiny amount of suspected allergens. If an allergic reaction occurs, the patient may experience temporary discomfort as a result of skin irritation, redness, and swelling. Results are usually available in 30 minutes to 48 hours.
- Blood Tests: In this method, blood is drawn and then analysed in a laboratory. Blood tests allow for the testing of a larger variety of allergens, and they can take several days to get the results. They are especially recommended for people with long-term skin disorders like eczema or psoriasis to avoid further irritation that skin tests may cause.
Fall allergies are usually diagnosed by a healthcare professional through a review of an individual’s medical history and an assessment of their symptoms. To determine whether an individual has allergies, consult with a doctor and book a test for allergy with Dr Lal PathLabs today!
FAQs
1. What are the main causes of fall allergies?
The common triggers of fall allergies include ragweed pollen, mould and mildew, dust mites, and pet dander. These allergens are prevalent during autumn and can cause allergic reactions.
2. What are some effective seasonal allergies treatments?
Treatments for seasonal allergies include steroid nasal sprays to reduce inflammation, antihistamines to control itching and sneezing, decongestants for relieving nasal stuffiness, and immunotherapy for long-term desensitisation to fall allergens.
