My nose keeps running nonstop indoors during winter and I am not sick at all. What is causing this?

Using humidifiers to add moisture back into the air can help alleviate this issue, keeping nasal passages from drying out and reducing the need for the body to produce excess mucus.

Vasomotor rhinitis is a condition characterized by a runny nose that is not caused by allergies or infections. Instead, it results from the overactivity of the nasal nerves, which can be triggered by environmental factors like changes in temperature or humidity. During winter, moving from the cold outdoors to warm indoors can stimulate these nerves, leading to increased mucus production.
