A runny nose when you have a cold is not detoxification. A runny nose is mainly caused by bacterial or inflammatory infections that stimulate the mucous membrane of the nasal cavity and increase the exudation of secretions. However, in the process of sneezing and sniffling, patients with colds may excrete germs outside the body, and others may be infected through contact with droplets. Therefore, it is important to take good personal protection to avoid infection. Pay attention to rest when the runny nose, eat a light diet, eat more vitamin-rich vegetables and fruits, and ensure sufficient sleep on a daily basis to avoid staying up late. Prolonged runny nose is difficult to relieve, it is recommended to consult a doctor in a timely manner, and follow the doctor’s instructions for treatment.
