When we cry, the production of tears increases significantly, and excess tears may accumulate in the eyes. These tears contain a mixture of water, mucus, oils, and antibodies, which serve to lubricate and protect the eyes. The burning sensation experienced when excess tears and mucus are present in the eyes can be attributed to a few factors:
Osmolarity: Tears have a specific balance of salts and other components to maintain their osmolarity (salt concentration). When there's an excessive amount of tears or mucus, the osmolarity may change, causing irritation and a burning sensation.
Inflammation: When we cry due to strong emotions or irritants, our eyes may become inflamed. Inflammation triggers a release of certain chemicals that can cause a stinging or burning sensation.
Acidity: Tears and mucus can sometimes be slightly acidic, especially during emotional crying. This slight acidity can cause irritation in the eyes.
Stress response: Crying, particularly during emotional moments, can lead to increased stress levels. Stress and emotions can impact the nervous system and lead to sensations of burning or discomfort.
Eye fatigue: Excessive crying can lead to eye fatigue and strain, which can further contribute to the burning sensation.
Increased sensitivity: When we cry, our eyes may become more sensitive to light, air, and other environmental factors, which can exacerbate the burning feeling.
It's important to note that excessive tearing or mucus production in the eyes may be a sign of an underlying issue, such as allergies, infections, or eye irritation. If the burning sensation persists or is accompanied by other concerning symptoms, it's advisable to consult an eye care professional for a proper evaluation and appropriate treatment.
