Sneezing while sleeping is possible, but it’s relatively rare compared to sneezing while awake. When we sleep, our bodies typically enter different stages, including non-rapid eye movement (NREM) and rapid eye movement (REM) sleep. During REM sleep, when most of our dreaming occurs, our muscles, including those in the throat and nasal passages, are more relaxed.
However, sneezing is a reflex action triggered by irritants in the nasal passages or by other stimuli. It’s an involuntary response mediated by the nervous system. Even though our muscles are more relaxed during sleep, the reflex arc responsible for sneezing can still be triggered by these irritants.
Several factors might increase the likelihood of sneezing during sleep.
01. Allergens: If you’re allergic to something in your sleeping environment, such as dust mites, pet dander, or pollen, it could trigger sneezing even during sleep.
02. Irritants: Other irritants like smoke, strong odors, or particles in the air could also lead to sneezing.

03. Infections: If you’re suffering from a cold or respiratory infection, your nasal passages may be more sensitive, making sneezing during sleep more likely.
04. Position: Sleeping on your back may make it more likely for nasal secretions to accumulate in your nasal passages, potentially triggering a sneeze.
05. Dreaming: Some people report sneezing during particularly vivid dreams, although the mechanism behind this is not fully understood.
While sneezing during sleep is possible, it’s not a common occurrence for most people. The body’s natural tendency to reduce sensory responsiveness during sleep often dampens reflex actions like sneezing. However, for individuals with heightened sensitivity or specific conditions, it might still happen.
