6. Sneezing
Sneezing is one of the body’s natural reactions and defense mechanisms to fight any foreign objects, such as dust and pollen, that enter the body by involuntary pushing or expelling them out. Frequent sneezing is a common sign and symptom of upper respiratory tract infection due to the irritation of the breathing tracts and the presence of pathogens.
In most cases, sneezing does not result in any harm or pain except for uneasiness and discomfort. A patient who regularly sneezes should be aware of his or her surroundings as this simple act may cause the spread of viruses and bacteria.
