Have you ever wondered why as soon as you go to sleep, you don't sneeze anymore?
Well... the Naked Scientist, Dr Chris Smith might have the answer.
The simple fact [is] that when you are in bed at night, you are laying recumbent and you're breathing less. So perhaps your exposure is less.— Dr Chris Smith, The Naked Scientist
You may also if you have a partly blocked up nose because you are having rhinitis because of allergy, you may be mouth breathing which means you are less lightly to deposit the things into your nose and make yourself sneeze.— Dr Chris Smith, The Naked Scientist
And also when you are inside the house asleep, probably your exposure to the allergen may be reduced. If the allergen is something in the environment and is less in your house, then it may be a combination of all of those things.— Dr Chris Smith, The Naked Scientist
He added that in essence when you are sleeping you are breathing less, therefore all of these reactions are going to be less pronounced.
