Pepper water cannot be used to treat snoring. Snoring can be caused by nasal and oropharyngeal diseases, which need to be treated acutely for the diseases. There are many reasons that may cause snoring, and it is necessary to find the reasons and then carry out the relevant treatment. For example, Obstructive Sleep Apnea Hypoventilation Syndrome is a disease caused by stenosis of the oropharynx, nasal cavity and nasopharynx, or laryngopharyngeal and laryngeal cavity lesions. In addition, this disorder is also associated with obesity. Other diseases that may cause snoring are simple snoring and hypothyroidism. Pepper water for snoring belongs to folk remedies and has no scientific basis, and the effect of treating snoring is not clear. Patients can adjust the sleeping position, take side lying when sleeping, or can wear a breathing machine to improve the symptoms of snoring. It is recommended to find the specific cause under the guidance of the doctor and then carry out targeted treatment.
