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 are
continually 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,
other chemicals found to be
present in emotional tears
and yet absent in basal and
reflex tears Current thinking
has it that crying is beneficial
to the body’s physical
and emotional health, as it
helps the body to dispose of
these 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
