Medically, there are two types of allergic rhinitis: perennial rhinitis and seasonal rhinitis, and it is important to distinguish the two diseases clinically.

Perennial allergic rhinitis, which is defined as allergic rhinitis with symptoms lasting more than nine months per year, is mostly caused by indoor allergens, such as dust mites or their feces. Despite the perennial nature of the attacks, or the severity of the symptoms is different throughout the day, aggravated at the time of year when the mites multiply the most. Perennial allergic rhinitis has symptoms all year round. Children, unable to express it, often show it by pushing their noses, making faces, and green eye sockets.

Autumn allergic rhinitis, on the other hand, only flares up during specific seasons each year and is caused by flowers, grasses and trees. Therefore, seasonal rhinitis, also known as chilblain fever or hay fever, its onset has obvious seasonality, mostly occurring in the spring and fall, and in the fall is more.

Some data show that in the north of China, the main cause of seasonal allergies is a pollen called "artemisia" and ragweed pollen. Every year in August and September, the autumn high, a lot of pollen in the air, easy to lead to the patient's illness. By the beginning of October, the symptoms disappear. This is true year after year.
