Abstinence is a self-enforced restraint from indulging in bodily activities that are widely experienced as giving pleasure. Most frequently, the term refers to sexual abstinence, but it can also mean abstinence from alcohol, drugs, food, etc. Because the regimen is intended to be a conscious act, freely chosen to enhance life, abstinence is sometimes distinguished from the psychological mechanism of repression. The latter is an unconscious state, having unhealthy consequences.
