    How to Sneeze: Understanding the Science and Etiquette of Sneezing

    Sneezing is a natural reflex that helps our bodies expel irritants and keep our respiratory system healthy. However, it is important to sneeze properly to prevent the spread of germs and maintain good hygiene. In this article, we will explore the science behind sneezing, the etiquette of sneezing, and provide valuable insights on how to sneeze effectively.

    The Science Behind Sneezing

    Sneezing is a complex physiological process that involves multiple organs and systems in our body. When an irritant, such as dust or pollen, enters our nasal passages, it triggers a series of events that lead to a sneeze.

    The process begins with the activation of specialized nerve endings in the nasal lining, called the trigeminal nerve. These nerve endings detect the presence of irritants and send signals to the brainstem, specifically the sneeze center, located in the medulla oblongata.

    Once the sneeze center receives the signal, it initiates a reflex response that involves the contraction of various muscles. The diaphragm, intercostal muscles, and abdominal muscles all work together to create a forceful expulsion of air from the lungs. This forceful expulsion helps to clear the irritant from the nasal passages.

    It is worth noting that sneezing is not only triggered by irritants but can also be a response to other stimuli, such as bright lights or sudden temperature changes. This phenomenon, known as the photic sneeze reflex or ACHOO syndrome (Autosomal Dominant Compelling Helio-Ophthalmic Outburst), affects approximately 18-35% of the population.

    The Etiquette of Sneezing

    While sneezing is a natural bodily function, it is essential to practice proper etiquette to prevent the spread of germs and maintain good hygiene. Here are some guidelines to follow when sneezing:

    • Cover your mouth and nose: When you feel a sneeze coming on, use a tissue or the crook of your elbow to cover your mouth and nose. This helps to contain the droplets released during a sneeze and prevents them from spreading to others.
    • Avoid using your hands: It is best to avoid sneezing into your hands, as this can easily transfer germs to surfaces or other people through touch. If you do sneeze into your hands, make sure to wash them thoroughly with soap and water or use hand sanitizer.
    • Dispose of tissues properly: If you use a tissue to cover your sneeze, dispose of it immediately in a trash bin. Leaving used tissues lying around can contribute to the spread of germs.
    • Wash your hands: After sneezing, it is crucial to wash your hands thoroughly with soap and water for at least 20 seconds. This helps to eliminate any germs that may have been transferred to your hands during the sneeze.
    • Use hand sanitizer: If soap and water are not readily available, use an alcohol-based hand sanitizer with at least 60% alcohol content. Apply enough sanitizer to cover all surfaces of your hands and rub them together until dry.

    How to Sneeze Effectively

    While sneezing is a reflex that we cannot control, there are ways to sneeze more effectively and minimize the risk of spreading germs. Here are some tips:

    • Look away from others: If you feel a sneeze coming on, try to turn your head away from people around you. This helps to reduce the chances of droplets reaching others.
    • Keep a distance: Whenever possible, maintain a distance of at least six feet from others when sneezing. This is especially important in crowded places or during times of illness outbreaks.
    • Use disposable tissues: Keep a pack of disposable tissues with you at all times. These can be used to cover your sneeze and then easily disposed of afterward.
    • Avoid touching your face: Touching your face, especially your eyes, nose, and mouth, can increase the risk of transferring germs. Try to avoid touching your face before and after sneezing.
    • Practice good respiratory hygiene: In addition to sneezing properly, it is important to practice good respiratory hygiene in general. This includes coughing or sneezing into your elbow, using tissues when necessary, and washing your hands regularly.


    Q: Can holding in a sneeze be harmful?

    A: Holding in a sneeze can potentially be harmful. When you hold in a sneeze, the pressure that builds up in your respiratory system can cause damage to your eardrums, blood vessels, or even lead to a rupture in rare cases. It is best to let the sneeze out naturally or sneeze into a tissue or your elbow.

    Q: How far can droplets from a sneeze travel?

    A: Droplets from a sneeze can travel at high speeds and reach a distance of up to six feet. This is why it is important to maintain a safe distance from others when sneezing, especially in crowded places.

    Q: Can allergies cause more frequent sneezing?

    A: Yes, allergies can cause more frequent sneezing. When you have allergies, your immune system overreacts to harmless substances, such as pollen or pet dander, triggering sneezing as a way to expel the irritants from your body.

    Q: Why do some people sneeze multiple times in a row?

    A: Sneezing multiple times in a row, known as a sneezing fit, can be caused by various factors. It could be due to a particularly strong irritant, such as pepper or dust, or it could be a result of hypersensitivity in the nasal lining. Sneezing fits are generally harmless and subside on their own.

    Q: Can sneezing spread diseases?

    A: Yes, sneezing can spread diseases. When you sneeze, droplets containing viruses or bacteria are expelled into the air. If these droplets are inhaled by others or land on surfaces that are touched by others, it can lead to the transmission of diseases, such as the common cold or flu.


    Sneezing is a natural reflex that helps our bodies expel irritants and maintain respiratory health. By understanding the science behind sneezing and practicing proper etiquette, we can prevent the spread of germs and promote good hygiene. Remember to cover your mouth and nose when sneezing, dispose of tissues properly
