Sneezing is a common occurrence, but what about when we're asleep? Well, it turns out that it is possible to sneeze in your sleep, but only during certain stages of sleep. Sleep is divided into several stages, from light sleep (non-rapid eye movement or NREM sleep) to deep sleep (rapid-eye movement or REM sleep). Sneezing typically occurs during the earlier stages of sleep when it's easier to be affected by external stimuli, such as allergens. During REM sleep, many muscles in the body are temporarily paralysed, making it unlikely that a person can sneeze. So, if you've ever felt like you've sneezed in your sleep, it's probably because you were in a light sleep cycle and were already partially awake.

Sneezing during sleep is rare, and usually occurs during light sleep
Sneezing is a common occurrence, but it is less common to sneeze while sleeping. Sneezing is a reflex triggered by irritation of the nasal lining or, less commonly, the lining of the lungs. During sleep, the body cycles through two types of sleep: non-rapid eye movement (NREM) sleep and rapid eye movement (REM) sleep. NREM sleep consists of three stages that progress to deeper sleep in each sleep cycle. REM sleep usually begins about 90 minutes after sleep onset, and it is characterized by quick eye movements, increased brain activity, heart rate, and blood pressure. Dreaming also occurs during this stage.
While it is generally believed that a person cannot sneeze during REM sleep, sneezing may be possible during the early, light stages of the sleep cycle. During REM sleep, many muscles in the body are temporarily paralyzed, making it unlikely that a person can sneeze. In contrast, during the early stages of sleep, individuals are more vulnerable to external stimuli, such as allergens or loud noises that can trigger sneezing. It is important to note that sneezing during light sleep may require at least partial awakening, but there is limited research to confirm this.
The reason sneezing is thought to be unlikely during REM sleep is due to the paralysis of the reflex muscle contraction. This paralysis causes the relevant muscles involved in sneezing to become inactive. Additionally, during REM sleep, the brain responds less to nerve messages, further suppressing the sneeze reflex. While sneezing during sleep is rare, it is not a cause for concern and is no different from sneezing while awake.
If sneezing is interfering with your quality of sleep, there are some strategies you can employ. These include using air filters, changing furnace filters, and washing your bedding regularly in hot water to remove potential irritants, allergens, and dust mites. Establishing a bedtime routine and limiting exposure to pet hair can also help improve sleep hygiene and potentially reduce sneezing triggers.

Sneezing is unlikely during REM sleep, when muscles are paralysed
Sneezing is a reflex triggered by irritation of the nasal lining or, less commonly, the lining of the lungs. It is an involuntary action that can happen when your nose or throat is irritated. Sneezing is a common occurrence, but it is less common to sneeze in your sleep. While it is possible to sneeze in your sleep, it usually occurs during the earlier, lighter stages of sleep.
Sleep is divided into several stages, with the deepest stage being rapid eye movement (REM) sleep. During REM sleep, dreaming occurs, and the eyes move rapidly behind closed eyelids. Brain activity, heart rate, and blood pressure ramp up during this stage. The body also experiences muscle atonia, where muscles are temporarily paralysed or lose all their strength. This paralysis makes it unlikely that a person can sneeze during REM sleep.
During REM sleep, the nerves that help trigger a sneeze are at rest, and the body is less vulnerable to irritation. The neurotransmitters are shut down, so even if an allergen enters the nasal cavity, histamines are not released, and a sneeze is not triggered. This is supported by the fact that sneezing usually requires at least partial awakening, which does not occur during REM sleep.
While sneezing during REM sleep is unlikely, it is possible to sneeze during the earlier, lighter stages of sleep, such as non-rapid eye movement (NREM) sleep. During these stages, the body is more vulnerable to external stimuli, such as allergens or loud noises, which can trigger a sneeze. While it is possible to sneeze during NREM sleep, it typically leads to waking up to sneeze.

Sneezing is a reflex triggered by irritation of the nasal lining
The sneeze reflex involves the contraction of various muscles and muscle groups throughout the body, including the eyelids. The powerful nature of a sneeze is due to the involvement of multiple organs in the upper body, such as the face, throat, and chest muscles. Sneezing helps to expel mucus and other contaminants from the body, acting as a protective mechanism to keep the nasal cavity clean.
While sneezing is a common occurrence, it is less common to sneeze in your sleep. Sleep is divided into different stages, including non-rapid eye movement (NREM) sleep and rapid-eye movement (REM) sleep. Sneezing typically occurs during the earlier, lighter stages of sleep when individuals are more susceptible to external stimuli. During the deeper stages of REM sleep, many muscles in the body are temporarily paralysed, making it unlikely for a person to sneeze.
Although sneezing in your sleep may be unusual, it is generally not a cause for concern. However, if persistent or severe sneezing interferes with your quality of life, it is recommended to consult a healthcare professional to rule out any underlying medical conditions. Overall, sneezing is a natural reflex that helps maintain respiratory health by expelling irritants and contaminants from the body.

Sneezing during sleep is more common in children than adults
Sneezing is a reflex triggered by irritation of the nasal lining or, less commonly, the lining of the lungs. It is an extremely common occurrence, but it is less common to sneeze in your sleep. Sneezing in your sleep is no more cause for concern than it is during waking hours. However, it can be bothersome and interrupt your sleep.
Sneezing during sleep is believed to be more common in children than adults. This is because sneezing is a reflex that requires input from the senses and work from the muscles. During the REM stage of sleep, the body's muscles are temporarily paralysed, and the brain shuts down the body's reflex responses. Therefore, it is unlikely that a person can sneeze during REM sleep.
During the first three stages of sleep, the brain registers less and less input from the senses, and the muscles become more relaxed. Sneezing typically occurs during the earlier, lighter stages of sleep when the body is still vulnerable to external stimuli. If you are in a deep sleep, you are less vulnerable to irritation.
If you are concerned about sneezing during sleep, there are several steps you can take to reduce potential triggers. These include removing allergens from your bedroom, such as pollen and pet dander, and washing your bedding regularly.

Sneezing during sleep is not a cause for concern
Sneezing is an involuntary reflex that occurs when your nasal lining is irritated by allergens, viruses, or particles like dust. It is a natural response that helps clear your nasal passages of germs and irritants. While sneezing is quite common, sneezing in your sleep is less so.
During the early stages of sleep, it may be possible to sneeze without fully awakening. However, there is limited research on this topic, and no definitive evidence has been published to confirm whether sneezing can occur during light sleep without some level of awakening.
If you feel like you have sneezed in your sleep, it is more likely that you were in a light sleep cycle or were already starting to wake up naturally. The same biological processes that suppress sneezes while you are in deep sleep also prevent coughing. It is important to note that sneezing during sleep is not something that should interrupt your sleep.
If you are concerned about sneezing at night, there are several steps you can take to reduce potential triggers. Maintaining good sleep hygiene, such as regularly washing your bedding and limiting exposure to allergens, can help minimise irritants and improve your sleep quality.

Frequently asked questions
Sneezing while sleeping is usually a sign that you are in the early stage of sleep or are already starting to wake up naturally. Sneezing is a reflex triggered by irritation of the nasal lining or, less commonly, the lining of the lungs. This irritation is often caused by allergens, a virus, or small particles like dust.
During deep sleep, also known as REM sleep, your body enters a state of paralysis. This paralysis prevents your body from acting out dreams and ensures you reach deeper stages of sleep. Since the muscles are not actively functioning, it is impossible to sneeze.
If you are concerned about sneezing at night, you can take steps to reduce potential sneezing triggers. This includes regularly cleaning your bedding to remove potential irritants, allergens, or dust mites. You can also use air filters, especially in the area where you sleep, and limit your exposure to pet hair.
