Yesterday we mentioned that we have three types of tears. The first type is basal tears which lubricate the eye. The second is reflex tears which help to flush irritants from the eye. Each of those types has a different chemical composition. There is also a third unique type of tears. We call them PSYCHIC TEARS.
These tears are produced by intense emotional stress which can be pleasure, anger, suffering, mourning, or pain. Again, they have a different chemical composition from basal or reflex tears. These tears contain large amounts of protein-based hormones – prolactin, adrenocorticotropic hormone, and leu-enkephalin which is a natural painkiller.
The hypothalamus in the brain has a degree of control over the autonomic nervous system. In a complex process involving neurotransmitters and receptors, the lacrimal gland is stimulated to produce tears. Studies have shown that the shedding of psychic tears is a significant part of the emotional adjustment to stress. Ongoing studies are examining whether mental illness can be affected by the shedding of psychic tears.
We would never have thought that tears could be so complicated. We also find it interesting that tears have different connotations in the Bible. In Luke 7:38 a woman washes the feet of Jesus with her tears. Mark 9:24 tells of a father crying out with tears. Acts 20:19 and 31 show tears used in a different context. Revelation 7:17 and 21:4 speak of God wiping away ALL tears indicating a realization of all the services that tears provide.
A study of tears is a beautiful reminder of David’s statement of Psalms 139:14: “I will praise you, God, for I am fearfully and wonderfully made: marvelous are your works.” Tears show us just one more example of God’s design of our bodies to cope with life on Earth.
