Keep the air moist
If you are constantly in an air-conditioned room, such as working in the office for a long number of hours, keep a humidifier at your desk. When dry air irritates your nose and throat, more mucus will be formed in an attempt to keep your nose and throat moist. Placing one in the bedroom can help you to achieve better sleep too by keeping your nose unblocked and prevent a sore throat.
