What is cumulative risk?

Cumulative risk refers to the overall increase in chances of negative outcomes that result from repeated exposure to risky behaviors or situations over a period of time. This concept emphasizes that individual risks can accumulate and lead to greater overall risk as one engages in or is exposed to more risky actions. For instance, if a teenager engages in reckless driving, substance abuse, or other dangerous activities repeatedly, the likelihood of adverse consequences—such as accidents, health issues, or legal troubles—grows significantly.

This understanding is crucial as it helps individuals recognize that even small, seemingly harmless risky actions can add up, potentially leading to serious problems. By identifying and mitigating cumulative risks, individuals can make more informed choices to improve their overall safety and well-being.
