In the early 1980s, biochemist, Dr. William H. Frey, II at the St. Paul-Ramsey Medical Center discovered that emotional tears contain high levels of stress hormones and protein, leading him to theorize that crying functions as a biological waste removal system.
🗂️Key Findings of the Study:
📑Chemical Distinction: Frey’s research found that emotional tears (psychic tears ) are chemically different from reflex tears (such as those caused by onions). Emotional tears were found to contain roughly 24% more protein.
📑Stress Hormone Removal: Emotional tears were shown to carry higher concentrations of stress-related compounds, including:
🗒️ACTH (adrenocorticotropic hormone): A key indicator of stress.
🗒️Prolactin: A hormone associated with stress and milk production, found in much higher levels in women after puberty.
🗒️Leucine-enkephalin: A natural opioid peptide and painkillers produced by the body during stress.
📑Excretory Process Theory: Based on these findings, Frey proposed that crying is an exocrine process- similar to exhaling, sweating or urinating - designed to physically expel toxic biological byproducts that accumulate during emotional distress.
NEVER HOLD BACK YOUR TEARS. Doing so too often can actually make you quite sick. The process of releasing emotional tears was created in you to actually help you feel better. ❤️
