Patients with rhinitis have more serious dark circles under their eyes, mainly for the following reasons: First, patients with rhinitis have nasal congestion during sleep, resulting in patients only being able to breathe with their mouths open, and repeated symptoms related to breath-holding and waking up during nighttime sleep, which very much affects the quality of sleep of patients, and because of the particularly poor quality of sleep, they cannot sleep smoothly at night, resulting in patients easily developing dark circles under their eyes, and this is currently inducing rhinitis patients to develop This is the most common cause of dark circles under the eyes. Second, patients with rhinitis often have symptoms related to repeated sneezing, itchy nose, and swelling of the nasal mucosa, resulting in poor blood circulation in the nasal cavity, which also tends to induce poor blood circulation in the structures surrounding the nasal cavity. Commonly, there is poor blood drainage on the surface of the nasal cavity and around the eyes, including poor blood drainage in the arteries and veins. Long-term poor blood circulation can easily lead to the symptoms of dark circles under the eyes, especially in children who rub their eyes frequently and repeatedly. All in all, if a patient develops dark circles under the eyes due to rhinitis, active clinical treatment should be given.
