It is possible to sneeze with eyes open, as closing them is an autonomic reflex. Sneezing serves as a defense mechanism to expel pathogens from the airways. Various stimuli cause sneezing, including viruses, allergens, and chemicals like piperine and capsaicin. A reflex known as 'photosneezia' triggers sneezing in response to light. The reason for closing eyes during a sneeze remains unclear; however, it may serve to protect the eyes from germs. The sneezing process helps clear mucus and obstacles from the nose.
Dr Huston reassures that it is 'absolutely possible' to sneeze with your eyes open, as closing them is simply an autonomic reflex.
Sneezing expels air from the lungs to clear the nose of mucus and prevent harmful substances from entering the airway, acting as a defense mechanism.
Chemicals such as piperine and capsaicin can irritate the nerve endings in the nose's mucous membranes, leading to sneezing.
Dr Huston suggests that the reflex to close eyes when sneezing may protect them from germs.
