Pharyngitis coughing at night especially strong, may be the secretion of the attachment of the posterior wall of the pharynx coupled with the vagus nerve excitation caused by the enhancement. 1. Secretions attached to the posterior pharyngeal wall: after suffering from acute and chronic pharyngitis, the pharyngeal mucosa is stimulated by inflammation, congestion, edema, hypertrophy, while the pharyngeal secretions will increase, and viscous, often attached to the posterior pharyngeal wall, stimulate the throat to produce discomfort, pharyngeal constriction, itchy; sleep at night due to the position of the reason, secretions are not easy to discharge, thus coughing symptoms. 2. Vagus nerve excitation: at night when you sleep, the vagus nerve excitability will increase, so that the smooth muscle contraction of the trachea, the narrowing of the lumen of the bronchial tubes, coupled with the pharyngeal secretion stimulation, so, pharyngitis patients cough at night is particularly strong. It is recommended that patients with pharyngitis, go to the hospital to find out the cause of the disease, and respect the doctor’s orders for treatment; usually prohibit the consumption of spicy and stimulating food in life, quit smoking and drinking, eat less sweets, in order to reduce the stimulation of the pharynx; a small amount of warm water before going to bed, which can alleviate the symptoms of coughing.
