Preventive health refers to measures taken to avoid diseases before they occur. Unlike reactive healthcare, which treats conditions after they manifest, preventive health is proactive. It involves regular check-ups, healthy eating, exercise, and screenings to detect potential issues early. In an age where chronic diseases like diabetes, heart disease, and cancer are widespread, preventive health isn’t just optional—it’s essential.
