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

Certain structural abnormalities in the nasal passages, such as a deviated septum or nasal polyps, can exacerbate the symptoms of a runny nose in winter. These conditions can obstruct normal airflow and drainage, leading to congestion and increased mucus production.

If structural issues are suspected, consulting with an ENT specialist can provide more insight and potential treatment options to alleviate symptoms.

Some medications, particularly those used for managing blood pressure, anxiety, or hormonal changes, can cause side effects like a runny nose. In winter, these effects may be more pronounced due to the other environmental factors at play.
