We can change our body shape, slow signs of aging, and learn to control our heart rate. Yet we are often helpless when crying. But why do women cry easier than men?
Several studies conducted to determine the causes behind crying and how many types of tears as well as differences in how men and women when crying.
Women are biologically more often moved to tears than men. Under the microscope, cells tear glands women look different from men. In addition, the tear ducts of men greater than women, so that if a man and a woman crying, her tears rolling down her cheeks faster.
According to bestselling author, "The Female Brain" Dr. Brizendine, social conditions play a role in resisting the urge to cry. When we experience physical pain or sorrow because of emotional or frustrated, brain amygdala, which is part of the limbic system or "emotional brain," stimulating signal. If the stimulus is big enough, the energy can move from emotional areas in the frontal motor strip. That's when the breath can develop into sobs.
Boys are often calm down before they cry. "The boy continued to be taught not to cry: to shrink their faces, to divert themselves," said Dr Brizendine,
Studies show testosterone helps increase the threshold between emotional stimuli and spilling tears. "It helps put the brakes on," said Dr Brizendine.
Studying the tears and crying is a complex process. There are two kinds of tears. Irritant tears help wash the eye from dust, and dirt. Emotional tears were created and released in response to emotional stimuli and physical pain.
All tears contain proteins, salts and hormones, among other substances, but the emotional tears have a higher protein level, said William H. Frey II, a neuroscientist and biochemist at the Hospital in St. Paul, Minn., which conducted research into the composition of tears.
One of the hormones in tears is prolactin, which is the catalyst of lactation. Similarly, in helping to produce milk. Prolactin also helps in the production of tears. At the time women reach the age of 18 years, they have 50 percent and to 60 percent of prolactin, higher in their bloodstream than men. "We believe this is one reason that women cry more easily," says Frey.
Nonetheless, much remains unknown. Humans are the only species that crying emotional effect, making it difficult to study the internal mechanism of tear gland. It is also not easy to stimulate cry in environmental studies that have been controlled.
