Lifestyle intervention refers to a type of research that focuses on implementing changes in an individual's daily habits and behaviors to improve their overall health and well-being. This can include changes in diet, exercise, stress management, sleep habits, and social support systems. Lifestyle interventions often target prevention or management of chronic diseases such as obesity, diabetes, heart disease, and cancer. Researchers in this area may conduct studies to assess the effectiveness of various lifestyle programs, interventions, or strategies on improving health outcomes and quality of life. The goal of lifestyle intervention research is to empower individuals to make sustainable changes in their lifestyle that can lead to long-lasting health benefits.
