Prevention to reduce ill health is crucial because it helps people live longer, healthier lives by avoiding diseases before they start, reduces the burden on healthcare systems, and saves costs associated with treating preventable conditions. This can be achieved through methods such as vaccinations to protect against infections, regular health screenings to detect issues early, and adopting healthy habits like balanced eating, physical activity, and avoiding harmful substances. Mental health can also be safeguarded through stress management and support services, while public health measures like clean air and safe water contribute to healthier communities overall.
