It is said that God can be found in tears as they are an important source of healing for mankind. They are a symbol of emotional response for only people can weep.
No one can deny the importance of human tears, they are secreted by your lacrimals—tiny, sponge-like glands which rest above the eye against the eye socket. The average person blinks every two to ten seconds. With every blink, the eyelid carries this miracle fluid over your eye’s surface.
One of the most important functions of tears is to oil your eyeball and eyelid but they also prevent dehydration of your various mucous membranes—and anyone with the ‘dry eye’ problem knows how painful this can be. A severe lack of this lubrication produces a condition requiring medication or therapy to save the victim’s eyesight.
Another function of human tears is that they bathe your eyes in lysozyme, one of the most effective antibacterial and antiviral agents known. This agent inactivates 90 to 95 per cent of all bacteria in a mere five to 10 minutes.
Tears provide an aid to a person to deal with emotional problems. Eye disorders like familial dysautonomia cause less tears, but also have a very low ability to deal with stressful events. The simple act of crying also reduces the body’s manganese level, a mineral which affects mood and is found in up to 30 times greater concentration in tears than in blood serum. They also found that emotional tears contain 24 per cent higher albumin protein concentration than tears caused by eye irritants.
Tears are an extremely effective method of communication, and can elicit sympathy much faster than any other means. Tears can be brought on not only by strong emotions, but also by mechanical irritation of your eye, infections, or illness.
Human tears constantly bathe each of your corneas (the transparent ‘windows’ of the eyes). Tears are just one of many miracles which work so well that we take them for granted every day.
