When it comes to our explosive reactions, the sneeze stands out as one of nature's most potent and complex responses to an irritant.
In reality, a sneeze is often simply a physical response to something in your body that needs removing - be it pollen, dust or viruses like the common cold or flu. This reaction occurs when microscopic hairs in our nose called cilia detect something out of place, triggering a nerve signal that prompts us to expel whatever's bothering us.
This protective mechanism might seem violent but is indeed an essential part of our immune system - one seen in many mammalian species.
Some people, however, experience sneezes without any apparent reason - whether triggered by bright light or simply the act of plucking their eyebrow. In these instances, it appears that a sneeze can occur due to non-allergenic triggers and isn't strictly linked to pathogens or air pollution.
A question many ask is: what does a sneeze reveal about impending danger? The answer is complex - while some research suggests exposure to polluted areas may trigger symptoms, the full extent of this connection remains unclear.
In terms of risk posed by our own sneezes, scientists struggle to provide concrete data as these events are infrequent and involuntary - unlike talking, breathing or coughing where we can make someone do them.
The possibility exists for an infected person to spread illness via a sneeze. Common colds, flu, tuberculosis, measles, respiratory syncytial virus, glandular fever, adenovirus, and others can be transmitted through sneezes - so taking precautions like using tissues or covering your mouth with your arm is key.
Lastly, if you find yourself stuck in a situation where someone's sneeze poses a risk to you - such as being cooped up without an escape route - donning a mask might help prevent transmission of airborne pathogens.
