The Physiology Of Crying, The Crying Of Newborns, The Crying Of Infants, The Crying Of ToddlersConclusion

Crying is a phenomenon that has puzzled people throughout the ages. People cry when they are sad, afraid, angry, in pain, or depressed, and yet people also cry when they are happy. Crying occurs in all emotions—it even contributes to the physiological well-being of an individual from birth to death. It is this versatility that makes crying so difficult to understand. Furthermore, tears are not always a function of emotion. Crying is a very important aspect of infant development that acts as a tool for communication.

No other study has given conclusive proof that other species cry. Crying is unique only to humans. Perhaps that is the reason for the complexity of this phenomenon. Complex beings bring forth complex issues that may prove impossible to sufficiently understand. Because of its versatility and unbiased relation to age, gender, and culture, crying will continue to puzzle people for years to come.
