In the early stage of allergic rhinitis, many people suffer from runny nose, sneezing and itchy nose. These symptoms linger for days and fail to ease despite various remedies, leading people to suspect seasonal allergic rhinitis. Triggered by the interaction between genetics and environment, allergic rhinitis can affect people of all age groups. So what exactly causes this condition?

Typical symptoms of allergic rhinitis include paroxysmal sneezing, which occurs several times a day with more than three sneezes each episode. It usually strikes in the morning, evening or after exposure to allergens. Patients also have profuse watery nasal discharge that may drip uncontrollably. Nasal congestion can be intermittent or persistent. Most patients experience nasal itching, and some gradually lose their sense of smell.
There are two major causes of allergic rhinitis. The first is heredity. Patients with allergic rhinitis usually have an atopic constitution, and the condition tends to run in families. Relevant genes have also been found to be associated with this illness. The second cause is exposure to allergens, which mainly come from animals, plants, insects, fungi and other sources. Some allergens are inhaled, while others are ingested with food. Inhaled allergens account for the majority of cases.
To prevent allergic rhinitis effectively, reduce indoor dust mites by cleaning carpets, bed linens and curtains, and use air purifiers. Those allergic to pollen or animal fur should avoid such allergens as much as possible. Do more exercise to improve physical fitness, and get rid of the bad habit of picking the nose. Keep warm as temperature changes can easily cause colds and trigger rhinitis. Check weather forecasts regularly and adjust clothing accordingly to minimize nasal irritation from cold air.
We are now in the high-incidence period of allergic rhinitis, especially for people with qi deficiency constitution, who are more likely to have recurrent attacks in spring. Therefore, such people need to regulate their qi deficiency in daily life and stay away from allergens, so as to effectively prevent repeated rhinitis flare-ups.
