A virtually identical reaction occurs with allergy to mold, animal dander, dust, and similar inhaled allergens.The pollens that cause hay fever vary from person to person and from region to region. Pollens that are carried by bees from plant to plant are seldom responsible for hay fever because the grains are large and have a waxy coating. Pollens that are carried by the wind are smaller and more often cause hay fever.
Examples of plants commonly responsible for hay fever include: trees (deciduous and evergreen), grasses, most flowers, and ragweed. In addition to individual sensitivity and regional plant prevalence, the amount of pollen in the air can be a factor in whether hay fever symptoms develop. Hot, dry, windy days are more likely to have increased amounts of pollen in the air than cool, damp, rainy days where pollen is washed to the ground.
Symptoms are Coughing, headache, itching of the nose, mouth, eyes, throat, skin, or any area, runny nose (rhinitis). Smell, impaired, sneezing, may be frequent, stuffy nose (nasal congestion), tearing, increased, throat, sore, wheezing.
