As an expert in the field of human physiology and aquatic activities, I can provide a detailed explanation on the possibility of sneezing underwater.
Sneezing is a reflex action that occurs when the nasal passages are irritated. It is a natural response to clear the nasal passages of irritants such as dust, allergens, and bright sunlight. However, when you are underwater, these typical irritants are not present, making it less likely for a sneeze to occur. But is it impossible? Let's delve deeper into the science behind this phenomenon.
Firstly, it's important to understand the mechanics of a sneeze. A sneeze is a forceful expulsion of air through the nose and mouth, triggered by the irritation of the nasal mucosa. This irritation can be caused by a variety of factors, including foreign particles, changes in temperature, or certain smells. The sneeze reflex is a protective mechanism that helps to clear the nasal passages and prevent the entry of harmful substances into the respiratory system.
Now, let's consider the conditions underwater. The absence of the usual irritants like dust and allergens significantly reduces the likelihood of sneezing. Moreover, the water pressure and the act of holding your breath can also contribute to a reduced urge to sneeze. However, this does not mean that it is impossible to sneeze underwater. There are a few scenarios where it might still be possible:
1. Underwater Irritants: While underwater, you may still encounter irritants such as chlorine from a swimming pool or saltwater from the ocean, which can cause irritation and potentially trigger a sneeze.
2. Pre-existing Irritation: If your nasal passages were already irritated before entering the water, the irritation may continue to persist underwater, leading to a sneeze.
3. Voluntary Sneezing: Some people may be able to voluntarily initiate a sneeze, even underwater. This is not a common ability and would require a certain level of control over the sneeze reflex.
4. Experiments and Anecdotal Evidence: There have been instances where individuals have reported sneezing underwater, often during experiments or as part of a challenge. The use of a feather or other stimuli to tickle the nose underwater, as mentioned in the reference, can indeed provoke a sneeze in some cases.
It's also worth noting that sneezing underwater can be potentially dangerous. The force of a sneeze can cause water to be expelled from the nose and mouth, which could lead to a risk of water entering the lungs, especially if you are not at the surface. This could result in choking or other respiratory issues.
In conclusion, while sneezing underwater is not a common occurrence due to the absence of typical irritants, it is not entirely impossible. Certain conditions and stimuli can still provoke a sneeze, but it is generally less likely and can pose risks if not done carefully. It's always best to practice safe and responsible behavior when engaging in aquatic activities to avoid any potential hazards.

Sneezing underwater isn't very likely because dust, allergens and bright sunlight -C the three things that normally provoke a sneeze are all absent. But after conducting careful experiments in the bath with a feather, I'm able to confirm it can be done!Aug 27, 2009
