Why do you sneeze when you wake up?

Sneezing as soon as you go to sleep, which occurs frequently, needs to be considered as having an allergic reaction of the airways. Allergic rhinitis is a chronic respiratory disease that can be caused by allergic factors indoors, such as dust, dust mites, hair from pets, green plants, and the presence of mold in the air conditioner when blowing on it, which is inhaled into the airway through the airflow and causes a hyper-reactive state in the airway mucosa. There is congestion, edema, and material exudation, which can be accompanied by irritating symptoms such as sneezing, runny nose, and itching of the nasal cavity, which cause this performance to occur frequently.
