Types and Benefits of Human Tears
- Tears are classified into three types: basal, reflex, and emotional. Basal tears, produced by the lacrimal gland, keep the cornea moist with water, oil, and mucus, averaging five to ten ounces daily. Reflex tears are triggered by irritants like smoke or onions, causing the eyes to produce excess water that may spill onto the cheeks. Emotional tears, linked to intense feelings, contain stress hormones and natural painkillers, potentially serving as a way to display vulnerability or seek support from others.
- Crying, a natural response to intense emotions, involves the limbic system and hypothalamus activating the automatic nervous system, leading to increased heart rate, sweating, and tears. While the evolutionary purpose of crying remains unclear, it is believed to help release stress hormones, offering relief. Crying can be a way to express emotions, seek support, and potentially appear submissive or vulnerable, showcasing its normalcy and potential benefits for stress relief.
