Health: Lifestyle, Risk Factors, and Health

What causes non-communicable diseases, and why do they develop over time? In this episode of GCSE Science Simplified, we explore the causes of non-communicable diseases, including cardiovascular disease, cancer, liver disease, lung disease, obesity, and malnutrition.You’ll learn how multiple risk factors interact, why lifestyle choices such as diet, exercise, smoking, and alcohol consumption have a major impact on health, and how conditions like obesity are measured using Body Mass Index (BMI) and waist-to-hip ratio. The episode also explains how lifestyle factors affect health at local, national, and global levels.Ideal for GCSE Biology revision, this episode is relevant for Edexcel, AQA, and OCR GCSE Biology students, as well as anyone wanting to understand how everyday choices influence long-term health.Keywords:GCSE Biology, Non-Communicable Disease, Lifestyle Factors, Obesity, Malnutrition, BMI, Smoking and Health, Alcohol and Liver Disease, Cardiovascular Disease, Health and Disease, Biology Revision
