Adult vaccination is an ongoing preventive health need, not just a childhood concern. This article explains how vaccines build immunity, what the adult schedule generally includes, and what the evidence shows about effectiveness and real-world uptake.

The relationship between alcohol consumption and health has been substantially revisited in recent research. This article examines the current evidence on alcohol and long-term health outcomes, including cancer risk, and how major health guidelines currently characterize that risk.

Cumulative ultraviolet radiation is the primary driver of skin cancer risk — and one of the most modifiable. This article covers what the evidence shows about UV damage, sunscreen use, sun-protective behaviors, and the vitamin D balance.

Oral health and systemic health are linked through biological pathways that research has increasingly documented. This article reviews the evidence connecting periodontal disease to systemic outcomes and what the research supports for preventive dental care.

Healthy aging means maintaining physical function, cognition, and quality of life — not just avoiding disease. This article covers what the research shows when lifestyle factors such as activity, sleep, nutrition, and social connection are studied together.

Health screenings aim to identify certain conditions or risk factors before symptoms appear. This article covers what major guidelines recommend across cardiovascular, metabolic, cancer, and infectious disease screening, and explains the factors that shape individual recommendations.
