Dry, irritated eyes are one of the most common concerns we treat at Beverly Hills Optometry. While artificial tears, prescription medications, and advanced in-office therapies are often essential, many patients are surprised to learn that something as simple as breathing can meaningfully influence tear production.
Research continues to highlight the connection between the respiratory system, the nervous system, and the ocular surface. Let’s explore how nasal breathing exercises may help support dry eye relief.
Your eyes are supported by a sophisticated feedback network known as the lacrimal functional unit (LFU) — a system that connects the ocular surface, the lacrimal glands, the meibomian glands, and the sensory and motor nerves that regulate tear production1.
One important component of this system involves the trigeminal nerve, which provides sensory input from the face, ocular surface, and nasal passages to the brain2.
Research suggests that approximately one-third of baseline tear secretion is driven by sensory stimulation from normal nasal airflow. Here is how it is thought to work:
In other words, steady, unlabored breathing with consistent airflow through the nose provides continuous sensory input that helps drive tear production — accounting for roughly 34% of basal tear output3,4.
When breathing is shallow, irregular, predominantly through the mouth, or chronically restricted (as can happen with stress), this sensory stimulation may be reduced — potentially affecting tear stability.
Stress shifts the body into sympathetic (“fight or flight”) mode 5. This can:
Chronic mouth breathing or shallow chest breathing — common during stress — may also reduce the nasal airflow stimulation that helps support basal tearing.
By contrast, slow diaphragmatic breathing can promote:
These exercises are simple, evidence-informed, and easy to integrate into a busy lifestyle.
This encourages steady nasal airflow and parasympathetic engagement.
Longer exhalation supports vagal tone and autonomic regulation 5. This can potentially help calm inflammation-driven dry eye symptoms.
Every 20 minutes:
This combination supports tear redistribution and reduces evaporative dry eye.
Breathing exercises are a supportive strategy, but they are not a substitute for a comprehensive dry eye evaluation.
At Beverly Hills Optometry, we assess:
If you experience persistent dryness, burning, fluctuating vision, light sensitivity, or excessive tearing, a customized treatment plan may include targeted therapies to restore ocular surface balance.
If dry eye symptoms are affecting your comfort or productivity, schedule a consultation with Beverly Hills Optometry. We’re committed to providing advanced, personalized care, while recognizing that sometimes, better eye health starts with something as simple as a breath.
