Hormones appear to be influenced by emotion and external behavior. For example, one's activity level may increase the production of a hormone, just as hormones often influence the way an individual feels. Hormones are found to impact behavior indirectly through emotional experiences. For example, an individual may feel a specific way as a result of hormone fluctuations but not behave or act out accordingly. The interaction between the emotion and environment play a large role on how hormonal influences are expressed behaviorally. Hormone production also appears to influence various behaviors.
