WHY DO I SNEEZE?

Sometimes dust, flakes of dead skin, pollution, microbes, or your booger buildup from a cold find their way into your nose's air passages. When mucous membranes in the lining of your nose detect these intruders, they send an urgent message to your brain: Unless a sneeze happens.

HOW DO I SNEEZE?

You don't have to do anything. Sneezing is a lightning-fast involuntary reaction in which your chest, stomach, throat, and face muscles work together to blast particles from your nasal passages. The whole process lasts less than three seconds, and it propels spit, boogers, chewed food, and other particles from your nose and mouth at nearly 100 miles per hour speed (161kph). Before you unleash a sneeze, your brain automatically signals your eyes to shut tight. You have no control over the process, and your blinkers stay firmly in place.

WHY DO I UPCHUCK WHEN I GET SICK?

If you catch the stomach flu (usually a virus in your guts), swallow food spoiled by bacteria, or overeat until your body rebels, your stomach will kick into reverse to eject whatever causing the trouble. Your guts churn, your head spins, and your throat begins to burn. Before you know it, blaaaagh! You've launched your lunch! Clammy skin, waves of uneasiness, and a queasy feeling known as nausea usually precede puking, giving you a heads up to hang your head over the toilet. Motion sickness (a condition brought on by winding roads, rocking boats, or back- to - again rides on the Tilt-a-Whirl) can lead to hurling.

WHY DOES THROW- UP BURN MY THROAT?

Your stomach contains powerful acids that help break down food, and some of this sour-tasting gastric juice gets pumped up and away when you puke. Although a wave of spit and mucus helps protect your throat and mouth when you vomit, you'll still feel the burn. Particularly forceful barfing sessions will pro0el puke into your sinuses and out your nose, producing an eye-watering sting. Nasty!

WHY DOES MY NOSE RUN WHEN I GET A COLD?

Your nasal membranes make moussaka- snot and this sticky substance serve as security against germs, dust, and pollen particle that would make breathing difficult if they reached your lungs. Moved along b tiny nostril hairs called Cilia, snot pummels, and pushes invading particles towards the exit_ your nostrils or dumps them down your throats. Your body produces nearly two gallons of mucus about 7.6 liters each week.

  You usually swallow all that snot without giving it a second thought. Catch a cold virus or come under an allergy attack, however, and the membranes pump up the volume. Your nose turns into a leaky snot faucet. You start coughing up the phlegm ( a type of mucus produced in your throats and lungs). A hacking cough and runny nose are your body's ways of flushing all the bad stuff.

WHY MEDICAL SCIENCE HASN'T FOUND A CURE FOR COMMON COLD?

You had to think curing a cause of the sniffles would be a cinch for scientists who invented artificial hearts and defeated lethal diseases like smallpox and polio. But eliminating the common cold is tricky because it's caused by more than 200 evolving viruses that all produce the same symptoms.

Thank you! Have a beautiful day.
