Have the flu and when breathing heat wheezing and crackle coughing up very little

Hello. Thank you for posting.

Humidifiers can help ease symptoms of a cold or another respiratory condition by putting moisture in the air. Most people who get influenza will recover in a week or two weeks, but some people will develop complications (such as pneumonia) as a result of the flu. Pneumonia, bronchitis, sinus and ear infections are examples of complications from flu. If you feel this cough is worsening see a doctor right away.
