Part of the reason your doctor tells you to drink plenty of fluids during a cold or flu is to prevent dehydration, says Meltzer. Dehydration causes mucus to become very thick, which is what leads to feelings of congestion. You re not only clogged up but also your body has a limitation in its ability to clear this heavier form of mucus, with all the trapped bacteria and viruses within. It makes the victim of a cold or flu feel like he is loved and comforted, says Meltzer. In addition to helping you stay hydrated, he says, the steam moistens respiratory passages, helping make the mucus thinner and therefore more easily cleared.
Some people notice that diary products make their bodies produce more mucus.
If you re one of those people, stay away from cream-based soups, as well as products such as milk and ice cream while you re sick. Although medication can t hasten the end of your cold or flu, it can offer you relief from at least some of the symptoms. Decongestants can open nasal passages, and cough syrups can make it easier to rest or help loosen mucus to make coughs more productive. If you have a fever, aspirin or acetaminophen will help bring it down. These or ibuprofen can help relieve muscle aches.
