Labor refers to the period of involuntary contractions of the uterine muscles that occurs prior to giving birth.

In psychology, labor (also known as childbirth or parturition) refers to the process of giving birth. Labor is a complex physiological process that involves contractions of the uterus and other changes in the body that allow the baby to be born.

Labor is a significant event in the lives of many people and can have significant psychological implications. For example, the experience of labor and childbirth can be a significant source of stress and anxiety for some people, particularly for those who are experiencing it for the first time. At the same time, the experience of giving birth can also be a source of pride and accomplishment for many people, and can have a profound impact on their sense of identity and self-esteem.

In psychology, research on labor and childbirth may focus on issues such as pain management, coping strategies, and the psychological impact of childbirth on mothers and fathers. Psychologists may also work with individuals or couples to address any psychological concerns or issues related to labor and childbirth.
