These are REAL tears - Onion tears are different!

Let’s say you’re feeling sad. Dr. William Frey is a biochemist and author of Crying: The Mystery of Tears. In his research, he compared the tears of women who cried for emotional reasons, to those who cried when they were exposed to onions. He found that the emotional tears contained high-levels of hormones and neurotransmitters associated with stress - the onion tears didn’t. In other words, Frey says the purpose of emotional crying is to release stress from our bodies. Holding back tears leaves you prone to anxiety, weakens your immune system, and impairs your memory and your digestive tract. So, when you feel like a good cry, go ahead and let it out.
