Almost everyone, adults and children alike, may have experienced an attack of eruption. When an attack of eruption occurs, it is often characterized by a short, frequent, rhythmic, and uncontrollable sound in the throat. At home, it may not feel like a retrograde, but if it is in a public place, especially a public place so quiet that even a pin can be heard on the ground, the amazing effect of retrograde can be imagined without me saying. If in the classroom, in the examination room or in a quiet meeting room, you can’t stop the retrograde, and keep “uh! Ugh! ……” what should I do? The way to get rid of erratic reflux is actually very simple and very effective. Inhale deeply and then hold your breath to do any of the following actions to get a significant effect in a quiet and non-intrusive state: exhale forcefully; or forcefully hook both fingers and pull each other forcefully; or sit on a stool and hug the desk or stool with both hands as hard as you want to break it. If it is convenient to run a few laps in the playground at the speed of 100 meters sprint or do pull-ups as fast as possible until a little can not go up or as fast as possible to trigger the arm strength or grip strength. Note that the above actions should be done after a deep inhalation and to hold your breath until you can’t hold it. The above methods are more effective when you are just starting to have an erratic reaction. In addition, you can also use distracting conversation method; pain or other discomfort stimulation method; or use paper or plastic bags outside the mouth and nose to do repeated breathing; or drink a large mouthful of water to swallow; or the middle knuckle of the index finger of both hands to press the middle of the upper eye orbit to do eye exercises, etc. are effective.
