Have you ever noticed your mouth becoming extremely dry when you're stressed or nervous? Whether it's during a live interview, public speaking, or any high-pressure situation, it can feel like all the moisture from your mouth has suddenly dried up. This isn't just in your head. In fact, there's a scientific explanation for it.
Speaking with the OnlyMyHealth team, Mehezabin Dordi, Clinical Psychologist, Sir HN Reliance Foundation Hospital, sheds light on the association.
Why Nervousness Causes Dry Mouth![]()
From dehydration to certain medications to various diseases like Sjogren's syndrome, HIV/AIDS, and diabetes, many factors can cause a dry mouth. However, nervousness or anxiety can also be a major cause of dry mouth.
"Nervousness triggers the body's "fight or flight" response, activating the autonomic nervous system, specifically the sympathetic branch. When this system is engaged, it reduces the production of saliva by inhibiting the salivary glands. This is because, during moments of stress or anxiety, the body prioritises survival mechanisms over non-essential functions like digestion, which includes salivation. The decrease in saliva leads to the sensation of dry mouth, also called xerostomia, which is a common symptom of anxiety," explains Dordi.

According to a 2016 study published in the Journal of Clinical and Diagnostic Research, anxiety patients (51%) had the highest prevalence of xerostomia, or dry mouth, followed by depression, bipolar disorder, and schizophrenia.
Dordi emphasises the importance of recognising the underlying cause of chronic dry mouth, as it can lead to various health problems.
He shares that saliva plays an essential role in oral health by helping to cleanse the mouth, neutralise acids, and prevent tooth decay. Therefore, a lack of saliva can result in an increased risk of cavities, gum disease, bad breath, and oral infections like thrush, the psychologist notes, adding that it can further complicate mouth activities like chewing or swallowing, which may affect digestion and nutritional intake.
