While most people naturally associate springtime with seasonal allergies when many trees, plants and grasses release pollens into the environment, each of the four seasons can actually trigger allergy symptoms in sufferers.
Because allergies are the body’s overactive immune response to what it perceives as foreign “invaders”, allergens come in many forms at all different times of the year.
Some of these may include:
Trees
Grasses
Pollens
Mold
Smoke
Insect bites and stings
Chlorine
Candy and celebratory food ingredients
Pine trees and wreaths

Allergies for All Seasons
Fall—
From August to November Ragweed releases pollen into the air causing itchy swollen eyes, runny nose, scratchy throat and sinus congestion for many who are allergic. Prevalent mainly in the Midwest and on the East coast, Ragweed does grow everywhere in the United States and becomes airborne the most throughout mid-September.
Other fall weeds that promote allergies include:
Burning bush
Cocklebur
Lamb’s-quarters
Pigweed
Sagebrush and Mugwort
Tumbleweed and Russian thistle
Winter—
From December through March, indoor allergies affect millions of people, triggering a multitude of symptoms. (Milder winter temperatures can also bring about early pollination of some plants and grasses).
Indoor allergens include:
Dust mites
Mold
Pet dander
Fireplace smoke
Pine trees (holiday trees)
Wreaths
Holiday candy ingredients
Spring—
One of the biggest allergens in springtime is pollen. April through June, these tiny grains are released into the atmosphere by trees, grasses, and weeds in order to fertilize other plants. When persons who are allergic ingest these tiny particles, the body’s immune system goes into overdrive.
The following trees, grasses and weeds are common offenders:
Trees
Alder
Ash
Aspen
Beech
Box elder
Cedar
Cottonwood
Cypress
Elm
Hickory
Juniper
