why do we sneeze with a cold

In most cases, symptoms of the common cold are not cause for concern and can be treated with fluids and rest. But colds are not to be taken lightly in infants, older adults, and those with chronic health conditions. A common cold can even be fatal to the most vulnerable members of society if it turns into a serious chest infection like bronchiolitis, caused by the respiratory syncytial virus (RSV). With the common cold, you are not likely to experience a high fever or be sidelined by fatigue. These are symptoms commonly associated with the flu. So, see your doctor if you have:
fever of 100. 4бF or higher a fever with sweating, chills, or a cough that produces mucus is 6 weeks or older and has a fever of 101. 4бF or higher has a blue or gray tint to their skin, especially around the lips, nose, and fingernails Ah-choo!

You feel a sneeze coming on, and you're helpless to stop it. That's because sneezing is a reflex. "When your nose gets irritated, your body automatically tries to clear your airways," says Todd Rambasek, MD, an allergist and immunologist with ENT & Allergy Health Services of Cleveland. The result is a sneeze. That split-second occurence is actually the final act of a precise chain of events. When the lining of your nose gets irritated в from the common cold, pollen, smoke, mucous, or pepper, for example в your body goes into reaction mode: Your chest muscles compress your lungs. The compression sends a blast of air upwards. The opening between your throat and mouth wants no part of it and slams shut. The powerful air, traveling 100 miles an hour, is forced out through your nose in the form of a sneeze. "For the most part, you can't control it.

Sneezes happen," says Mitchell H. Grayson, MD, a professor in the division of allergy and clinical immunology at the Medical College of Wisconsin in Milwaukee. When you sneeze, you reflexively close your eyes as part of the process. Urban legend says you can't open your eyes, even if you want. In fact, "it's very hard to do, but there's nothing saying you can't keep your eyes open when you sneeze," says Dr. Grayson. The Sneeze: To Each His Own Why do some people sneeze only once, while others can't seem to stop after two or three, or even four or five sneezes? "It's related to the level of irritation of the nose," Dr. Rambasek explains. You'll keep sneezing until what's irritating the lining of your nose в the mucosa в is cleared out. "Some people have bouts of sneezing," Grayson adds. "It's a neurologic reflex, and it depends on the person.

Some people may have 10 to 20 sneezes in a row. " Why do some people sneeze loudly and others softly? "To some extent, people can control the volume," Rambasek says. "It's like burping. Some people burp loudly and others are able to keep it soft. " Sneeze Causes A number of things can trigger a sneeze. Some of the more common sneeze causes are: to substances such as pet dander, or ragweed Irritants such as dust, strong odors, powder, or pepper Viruses that cause the common and often Some people find that when they step into bright light, it triggers a sneeze. This is known as a photic sneeze reflex and is believed to be a genetic trait. About one in four, and perhaps as many as one in three, people have this reaction. No one knows why, but it could be because the optic nerve crosses near the nerve responsible for the sneeze reflex, Grayson says. "Some of that signal may jump over. " A change in temperature is one of the most common reasons people sneeze. "Change in temperature is a classic irritant в going from hot to cold or cold to hot," explains Rambasek. "A lot of people sneeze when they go into a walk-in refrigerator or turn the air conditioning on in their car. " Take Care When You Sneeze When you sneeze, you release irritants back into the air.

Mom was right: You should with a tissue when you sneeze to prevent the spread of viruses and other germs that can cause the common cold and other illnesses. Or turn your head and sneeze into your shoulder if a tissue isn't handy. If you use your hands to cover your nose, be sure to wash them right after.
