Tears not only serve as an emotional response but also play a significant role in maintaining eye health and overall well-being. Here are some surprising health benefits of tears:
- Tears keep the eyes moist, preventing dryness and irritation. They expel dust, dirt, and other particles that may have entered the eyes.
- Tears contain a chemical called lysozyme, which has antimicrobial properties that help protect against infections. Tears also provide oxygen and nutrients to the corneal surface of the eye.
- Crying helps release stress hormones like cortisol, providing a sense of relief and calm.
- Tears trigger the release of chemicals like oxytocin and endorphins, which can improve mood and reduce pain.
- Emotionally triggered tears differ from basal tears, as they contain higher levels of stress-related hormones and toxins. Crying helps the body eliminate these substances.
- Crying activates the parasympathetic nervous system, helping the body relax and reduce physical pain.
- Tears help maintain a clean and smooth eye surface, which is essential for sharp vision.
- Lysozyme and other proteins in tears provide natural defense mechanisms, reducing the risk of eye infections.
