Why do temple runners burp when they take the job?

Burning incense causes various substances in the air to stimulate the respiratory tract. At this time, people with chronic pharyngitis or sensitive throat are prone to dry cough and burp.

The direct cause of hiccups is the involuntary contraction (spasm) of diaphragm, which can be caused by many factors, and air is quickly inhaled into the lungs. The gap between the two vocal cords suddenly narrowed, making a strange sound.

For example, overeating, eating spicy and greasy food, drinking alcohol or cold air stimulation may all cause involuntary spasm of diaphragm. It is very common in clinic and life. Under normal circumstances, short-term hiccups with obvious inducement and alleviation factors are generally not a big problem and have a good prognosis.
