If you have a runny nose and sneezing after running, you usually have to consider the appearance of rhinitis. At this time, the first thing to do is to stop running, because running will lead to faster breathing, and after the breathing is accelerated, the breathing airflow in and out of the nasal cavity will be accelerated, which can stimulate the nasal cavity to constantly appear runny nose and sneezing. In addition, antihistamines should be given to relieve, for example, cetirizine hydrochloride or loratadine can be taken orally to relieve the symptoms of runny nose and sneezing. Patients should also pay attention to keeping warm and avoiding exposure to cold air, which is also a common cause of acute attacks of rhinitis, as well as taking rest and avoiding exposure to allergic substances, including pollen and dust.
