WHY DOES PEPPER MAKES US SNEEZE ?



Our noses are designed to repel anything that enters through it except air. This is a kind of defence mechanism. The three main defences are the fine nasal hairs in the nostrils, mucus and sneezes – reflex actions caused when nerve endings in the mucus membranes are irritated.

WHY ONION MAKES US CRY ?


Onions produce a chemical irritant known as syn-propanethial-S-oxide. It stimulates the eyes' lachrymal glands so they release tears. Scientists used to blame the enzyme allinase for the instability of substances in a cut onion. Recent studies from Japan, however, proved that lachrymatory-factor synthase, is the culprit (Imani et al, 2002). It is not the odor from the onion that makes us cry, but the gas that the onion releases when cut. It is an irritant to both our noses and to our eyes. Cutting an onion arouses a gas contained within the onion. When this upwardly mobile gas encounters the water produced by the tear ducts in our eyelids, we cry !
