Following are the health benefits of tears:
1) Tears keep the eyes moist, preventing dryness and irritation. They remove dust, dirt and other particles from the eyes that have entered.
2) Tears contain a chemical called lysozyme. This enzyme with antimicrobial properties protects against infection. Tears also supply oxygen and nutrients to the cornea.
3) Crying helps release stress hormones such as cortisol, providing a sense of relief and peace.
4) Tears stimulate the release of chemicals such as oxytocin and endorphins, which can improve mood and reduce pain.
5) Emotionally triggered tears differ from reflex or basal types of tears because they contain a higher concentration of stress hormones and toxins. Crying can help the body eliminate these substances.
6) Tearing activates the parasympathetic nervous system, which can help the body relax and reduce the sensation of physical pain.
7) Tears also help maintain a clean and smooth surface of the eye which is essential for sharp vision. 8) Lysozyme and other proteins in tears provide a natural defense mechanism that reduces the risk of eye infections.
