Stress, cortisol, and social hierarchy

Area of Science:

• Endocrinology
• Social Neuroscience
• Psychology

Background:

• Cortisol, a key stress hormone, plays a crucial role in the body's physiological response to challenges.
• Social status is a significant factor influencing human health and behavior.
• Understanding the interplay between cortisol, stress, and social status is vital for public health.

Purpose of the Study:

• To synthesize existing literature on the relationship between cortisol levels, stress, and social status.
• To elucidate how different aspects of social status impact cortisol secretion and stress responses.
• To explore the bidirectional influence of cortisol on social status and behavior.

Main Methods:

• Systematic literature review of studies investigating cortisol, stress, and social status.
• Analysis of findings across diverse social contexts and species.
• Integration of physiological and psychological perspectives on the cortisol-status dynamic.

Main Results:

• Cortisol is typically elevated in individuals experiencing chronic lack or potential loss of social status.
• Lower cortisol levels are associated with stable, high social status, particularly when it confers a sense of control.
• Cortisol's dual role as a stress indicator and behavioral modulator influences the status-related cortisol profile.

Conclusions:

• The cortisol-status relationship is complex and context-dependent, influenced by perceived stressors, control, and responsibilities.
• Stable high social status may be both a cause and consequence of lower cortisol levels.
• Individual interpretation of status, including associated stressors and control, critically shapes the cortisol response.
