Functional health is the state of overall well-being that emphasizes how effectively a person is able to carry out daily activities and maintain balance in both physical and mental health. It goes beyond the absence of disease, focusing instead on the body’s ability to function optimally by addressing the underlying causes of health concerns. Functional health considers factors such as nutrition, sleep, exercise, stress, and lifestyle choices, recognizing that each plays a vital role in long-term wellness. Rather than only treating symptoms, functional health promotes a holistic approach that supports resilience, independence, and quality of life.
