Hallmarks of Health

Area of Science:

• Physiology
• Systems Biology
• Homeostasis

Background:

• Traditional definitions of health focus on the absence of pathology.
• A dynamic, organizational perspective offers a more comprehensive understanding of physiological well-being.

Purpose of the Study:

• To propose a new definition of health based on organizational and dynamic features.
• To identify the biological hallmarks that maintain physiological function.

Main Methods:

• Conceptual analysis of biological systems.
• Identification of key homeostatic and resilience mechanisms.

Main Results:

• Health is characterized by spatial compartmentalization, maintenance of homeostasis over time, and adequate responses to stress.
• Key features include barrier integrity, recycling and turnover, circuit integration, rhythmic oscillations, homeostatic resilience, hormetic regulation, and repair/regeneration.
• Disruption of these features leads to pathology.

Conclusions:

• Health is an active, dynamic process defined by the system's ability to maintain physiological integrity.
• Understanding these hallmarks provides a framework for assessing and promoting health.
