Health impact refers to the effect that various factors have on an individual's physical and mental well-being. These factors can include lifestyle choices, environmental conditions, and access to healthcare services. Understanding health impact helps identify risks and benefits associated with different behaviors and policies, ultimately guiding public health initiatives. Assessing health impact involves analyzing data to determine how specific actions or events influence health outcomes. For example, studies may evaluate the health impact of air pollution on respiratory diseases or the effects of exercise on mental health. This information is crucial for developing effective strategies to improve community health.
