Season Allergies

Here we are in spring, albeit a wet spring which may provide temporary relief for those that suffer from allergies, but eventually this time of year will mean a time of annoying symptoms. Approximately 20% to 30% of Canadians suffer from seasonal airborne allergies which are primarily caused by tree pollen. Respiratory allergies like seasonal allergic rhinitis, better known as hay fever can begin in the early spring and persist until late fall.

Seasonal allergy symptoms are caused when the immune system tries to protect the body from these harmless everyday substances.  Seasonal allergies are considered an oversensitive immune response, resulting in symptoms intended to remove the allergen, such as sneezing and runny nose too expel pollen; itchy, watery eyes to wash away foreign particles; congestion/ inflammation to block further entry of the allergen.

The most common symptoms of allergic rhinitis/hay fever include: 

·         Fatigue and general malaise
·         Nasal congestion, sneezing, runny nose, post nasal drip
·         Itchy nose, eyes and throat
·         Headaches, sinus pain, vertigo
·         Dark circles around the eyes
·         Wheezing, coughing and trouble breathing
·         Increased mucous production
·         Allergic rhinitis is also a risk factor for asthma

The most common medical treatment involves either prescription or over the counter antihistamine medication, corticosteroid sprays, and decongestants

Immune-enhancing supplements will help support the immune system without unwanted side-effects of medications.

Vitamin C In addition to immune enhancing effects, vitamin C it also prevents the formation of histamine. To maximize effectiveness, vitamin C is best taken with bioflavonoids — the natural pigments in fruits and vegetables — in divided doses spaced throughout the day. Bioflavonoids enhance the activity of vitamin C in the body and help to stabilize the cells which secrete the histamine. During allergy season take as much vitamin C your body will accept – to bowel tolerance. If you take 3,000 mg and start to get gas or bloating then 2000 mg is your tolerance, etc.  Many people can take upwards of 5,000 mg during allergy season or times when the immune system needs support.

Quercetin contains polyphenols, and flavonoids and it is known for its antioxidant activity and anti-allergic properties. The mechanisms of action contribute to the anti-inflammatory and immunomodulating properties of quercetin that can be utilized in treatment of allergic rhinitis. Common food sources include onions, broccoli, fruits (apples, berry crops, and grapes), black tea and red wine.

Quercetin is best taken with vitamin C mixed with bioflavonoids, as this improves the antihistamine effect. Quercetin may be effective for allergies, asthma, chronic obstructive pulmonary disease, bronchitis, sinusitis, cold and flu. Much like vitamin C, quercetin stabilizes the mast cells (specialized immune cells) that cause an allergic reaction, and decreases the release of histamine, helps to decrease allergy symptoms. 

Probiotics help to modulate the immune system and reducing inflammation, and improving common allergy symptoms like sneezing, itchy eyes, and congestion. Specific strains of lactobacillus and bifidobacterium are generally recommended to support gut health, which in turn reduces allergic responses.

Stinging Nettle: Studies suggest if can reduce symptom severity like sneezing, congestion, and itchy eyes by blocking histamine receptors and reducing inflammation.

Adrenal Support – for those who have long term stress, there is a good chance the adrenal glands need support. Chronic stress can lead to increased risk for allergies and worsening of allergy symptoms. There are various adrenal support options ranging from individual herbs such as ashwagandha or combined herbal formulas.

To reduce symptoms, you could also:

• Close windows in your home and car during the spring, summer and early fall when pollen counts are higher.
• Enclose pillows, mattresses and box springs in dust mite covers.
• Keep pets off couches and beds, and close doors to bedrooms you don’t want them to enter.
• Use filters in your vacuum cleaner and air conditioner to reduce the amount of allergens in the air.
• Use an air purifier
• Wash your hands often, especially after playing with pets. 
• Wear a hat and sunglasses to protect your eyes from pollen when you’re outside.

Note: if possible, start taking supplements prior to allergy season. I would recommend that my patients start taking vitamin C, quercetin and probiotics one month before their symptoms commonly start.
