What makes us Sneeze? When we breathe in, the inhaled air can contain dust, chemicals and other irritants that can be harmful to the body, particularly to organs in the respiratory system like the lungs. While the tiny hairs inside the nostrils (cilia) trap many of these particles, some will often get through. To help you out, your body reacts to try and forcibly expel the offending particles via the sneeze reflex arc. There are a number of other reasons why we sneeze, including to clear the nasal passages when you have a cold, to expel allergens if you are allergic to something, and even bright sunlight can cause some people to sneeze. When a stimuli is detected by the nerve endings in the nose, impulses are sent to the brain, which initiates a chain of physiological events that enable the body to rid itself of the unwelcome item. Over‐the‐counter antihistamines such as chlorpheniramine and diphenhydramine block this process and can relieve the symptoms. They can also make you sleepy and dry out your eyes, nose, and mouth. For chlorpheniramine : o Adults and teenagers—4 milligrams (mg) every four to six hours as needed. o Children 6 to 12 years of age—2 mg three or four times a day as needed. o Children 4 to 6 years of age—Use and dose must be determined by your doctor. o Children and infants up to 4 years of age—Use is not recommended . For diphenhydramine : o Adults and teenagers—25 to 50 milligrams (mg) every four to six hours as needed.

What makes us Sneeze?
When we breathe in, the inhaled air can contain dust, chemicals and other irritants that can be
harmful to the body, particularly to organs in the respiratory system like the lungs. While the tiny
hairs inside the nostrils (cilia) trap many of these particles, some will often get through. To help you
out, your body reacts to try and forcibly expel the offending particles via the sneeze reflex arc.
There are a number of other reasons why we sneeze, including to clear the nasal passages when you
have a cold, to expel allergens if you are allergic to something, and even bright sunlight can cause
some people to sneeze.

initiates a chain of physiological events that enable the body to rid itself of the unwelcome item.

and can relieve the symptoms. They can also make you sleepy and dry out your eyes, nose, and
