I thought this was a good article, so I'm sharing it with you!
Oh -- This one is good, too!
Apparently, when you cry because of emotional stress, you really are crying out negative emotion. Pretty interesting...
From the article:
"Emotional tears were found to contain high levels of hormones and neurotransmitters associated with stress. They also led to lower blood pressure, pulse rate and more synchronised brain-wave patterns. Dr. Frey concluded that the purpose of emotional crying is to remove stress chemicals. He says the continued presence of these substances -- when you hold tears in -- would keep you in a needless state of tension. Your body would then be prone to the negative effects of anxiety, including weakened immunity, impaired memory and poor digestion."
So, what are you waiting for? Have a good cry!
