1. Quit smoking and alcohol addiction: smoke can damage the respiratory mucosa, reduce the sensitivity of the respiratory tract, causing aggravation of respiratory symptoms; alcohol can reduce the movement of the muscles around the upper respiratory tract, increasing the occurrence of sleep breathing disorders, heavy snoring, nocturnal breathing disorders and hypoxemia, especially drinking alcohol before bedtime. 2. For obese people, it is necessary to actively reduce weight and strengthen exercise. Fat deposits in the soft tissues of the upper airway, small lumen and fat infiltration in the muscular tissues of the upper airway in obese people can cause relaxation of the muscular tissue connection, leading to increased compliance of the upper airway, resulting in airway collapse and poor breathing. 3. Sedative and sleeping drugs are prohibited before bedtime, so as not to aggravate the inhibition of the central regulation of respiration. Sedatives can reduce the movement of the muscles around the upper airway, increasing the occurrence of sleep apnea. 4. Take the side sleep position, especially the right side sleep position is appropriate to avoid the tongue, soft palate, uvula relaxation back during sleep, aggravating the upper airway blockage.
