Crying, or lachrymation, is the process of producing tears, which in human eyes are produced by glands under the eyelids People cry for a number of reasons: basal tears arecontinually produced to lubricate and clean the eyes, while reflex tears wash away irritants and foreign particles However,a third type of tears, emotional tears, are produced when a person cries.
When a person is hurt, physically or emotionally, the lachrymal glands sometimes constrict and produce emotional tears When a person is in an emotionally overwrought state,the body overreacts and produces a flood of hormones and other chemicals found to be present in emotional tears and yet absent in basal and reflex tears Current thinkinghas it that crying is beneficial to the body’s physical and emotion al health, as ithelps the body to dispose ofthese additional stress hormones and chemical toxins and is why people often feel better and calmer after a good cry Indeed,this view is now supported by scientific research Even the philosopher Aristotle believed that crying cleansed the mind of suppressed emotions.
Humans are the only animals to cry (although some suggest that gorillas and elephants might, too), largely—it is believed—due to their heightened sense of self-awareness.
