Humidity
Influenza thrives and transfers easier in dry environments, so decrease your exposure by creating more humidity in your home. Temporarily adding a cool-mist humidifier in the bedroom may make a sick person more comfortable, especially in winter, when dry indoor heat can easily exacerbate symptoms. Increased humidity can reduce nasal inflammation, making it easier to breathe. Adding a few drops of eucalyptus oil might also stimulate breathing. (Remember, the water used in humidifiers needs to be changed daily to avoid fungi and molds. For the same effect without a humidifier, take a long shower or linger in a steamy bathroom
