Some research shows that flu germs survive and spread more easily in dry air conditions. Therefore it is recommended to maintain indoor humidity levels during flu season. Using a humidifier can help achieve this.
Plus, inhaling moist air also eases nasal congestion and abates discomfort associated with a sore throat. One effective strategy is to take a hot shower inhaling steam or to use a steam vaporizer or a humidifier.
Steamy showers can ease moisturizing the nasal passages while also helping the individual to relax. When using a humidifier, make sure to keep it clean and free of mold and mildew growth. The damp air created by a humidifier can really be very helpful at night and help ease breathing.
