Lifestyle Impact on Physiology

Meaning

Lifestyle Impact on Physiology is the comprehensive, cumulative effect of an individual’s daily behaviors—including diet, physical activity, sleep quality, and chronic stress exposure—on the integrated function of the body’s organ systems and biochemical pathways. This impact is a powerful determinant of healthspan and disease risk, often overshadowing genetic predispositions. In the hormonal context, lifestyle choices are recognized as the primary modulators of the Hypothalamic-Pituitary-Adrenal (HPA) axis, insulin sensitivity, and sex hormone balance.
